 Exhibit 10.10 

CELL BIOSCIENCES, INC. 

AMENDED AND RESTATED EXECUTIVE EMPLOYMENT AGREEMENT 

for 
 Tim Harkness

 This Amended and Restated Executive Employment Agreement (the “Agreement”), made between Cell Biosciences, Inc. (the
“Company”) and Tim Harkness (the “Executive”) (collectively, the “Parties”), amends, restates and supersedes in its entirety the employment offer letter agreement between the Company and Executive
that was effective as of June 12, 2008 (the “Original Agreement”). This Agreement is effective as of February 3, 2011. 

WHEREAS, Executive is currently employed by the Company as its President and Chief Executive Officer,
pursuant to the Original Agreement; and 
 WHEREAS, Company desires to continue to employ Executive as
its President and Chief Executive Officer, and Executive is willing to continue such employment by Company, on the amended and restated terms and conditions set forth in this Agreement. 

NOW, THEREFORE, in consideration of the mutual promises and covenants contained herein and
for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereto agree as follows: 

1. Employment by the Company. 

1.1 Position. Executive shall serve as the Company’s President and Chief Executive Officer. During the term of Executive’s
employment with the Company, Executive will devote Executive’s best efforts and substantially all of Executive’s business time and attention to the business of the Company, except for approved vacation periods and reasonable periods of
illness or other incapacities permitted by the Company’s general employment policies. 
 1.2 Duties and Location. Executive
shall perform such duties as are required by the Company’s Board of Directors (“Board”), to whom Executive will report. Executive will serve as a member of the Board until the earlier of the severance of Executive’s
employment for any reason, or Executive’s death. Executive’s primary office location shall be the Company’s Santa Clara, California office. 

1.3 Policies and Procedures. The employment relationship between the Parties shall be governed by the general employment policies and
practices of the Company, except that when the terms of this Agreement differ from or are in conflict with the Company’s general employment policies or practices, this Agreement shall control. 







 2. Compensation. 

2.1 Salary. For services to be rendered hereunder, Executive shall receive a base salary at the rate of four hundred thousand
($400,000) per year (the “Base Salary”), payable in accordance with customary Company payroll procedures in effect for other executive employees and subject to standard payroll deductions and withholdings. Executive’s Base
Salary shall be subject to review and adjustment on an annual basis, subject to the terms set forth herein. Executive shall not receive any additional compensation for Executive’s service as a member of the Board. 

2.2 Bonus. Executive will be eligible to earn an annual cash bonus targeted at sixty percent (60%) of Executive’s Base Salary
(the “Annual Bonus”), which, if earned, will be paid by the end of the first quarter of the following calendar year. Executive will be eligible to receive the Annual Bonus based upon the Company meeting and/or exceeding specified
corporate sales goals (the “Sales Goals”) and Executive’s achievement of Chief Executive Officer-specific goals (the “CEO Goals”). The Sales Goals and CEO Goals will be mutually agreed upon by Executive and the
Board. The Sales Goals and CEO Goals will be established no later than March 15 for each calendar year. Except as otherwise provided in Section 7 hereof, Executive must remain an active employee through the last day of the applicable
fiscal year to be eligible to receive the Annual Bonus. 
 3. Standard Company Benefits. Executive shall be entitled to participate
in all employee benefit programs for which Executive is eligible under the terms and conditions of the benefit plans that may be in effect from time to time and provided by the Company to its employees. The Company reserves the right to cancel or
change the benefit plans or programs it offers to its employees at any time. If Executive elects to continue any current COBRA health insurance coverage rather than participate in the Company’s group health insurance plans, the Company will
reimburse Executive for Executive’s monthly health insurance premiums (for Executive, Executive’s spouse and any covered dependents) up to the maximum dollar amount the Company would contribute to Executive’s health insurance coverage
if Executive elected to participate in the Company’s group plan. 
 4. Vacation. Executive will enjoy four (4) weeks of
paid time off each year, the use and accrual of which will be governed in accordance with Company policy. 
 5. Expenses. The Company
will reimburse reasonable business-related expenses incurred by Executive in accordance with applicable Company policies, including but not limited to cellular phone/PDA expenses. 

  
 2. 








 6. Equity. 

6.1 Option Grants. Subject to the Compensation Committee of the Company’s Board (the “Compensation Committee”) and
the Board’s annual review and approval, Executive may be eligible to receive stock options to purchase shares of Common Stock, as determined by the Compensation Committee and the Board, in their sole discretion. 

6.2 Acceleration.  

(i) Single Trigger Benefits. In the event a Change of Control (as defined below) occurs at any time during Executive’s
employment, the vesting of any unvested shares or options then held by Executive shall be accelerated by six (6) months. 
 (ii)
Double Trigger Benefits. If, within one (1) month before and thirty-six (36) months after a Change of Control, Executive’s employment is terminated by the Company without Cause (as defined below) or Executive resigns for Good
Reason (as defined below) (each a “Change of Control Termination”), one hundred percent (100%) of all shares or stock options which are not vested at the time of Executive’s termination will accelerate and become fully
vested. 
 7. Termination of Employment; Severance. 

7.1 At-Will Employment. Executive’s employment relationship is at-will. Either Executive or the Company may terminate the
employment relationship at any time, with or without Cause or advance notice. 
 7.2 Termination Without Cause; Resignation for Good
Reason. If, at any time other than during the period commencing one (1) month prior to the effective date of a Change of Control and ending thirty-six (36) months following the effective date of the Change of Control, the Company
terminates the Executive’s employment without Cause, or Executive resigns for Good Reason, and such termination constitutes a Separation from Service (as defined below), the Company shall provide the Executive with the following severance
benefits: 
 (i) A cash severance benefit in an amount equal to the sum of (i) twelve (12) months of the Executive’s
Base Salary, (ii) the prior year’s Annual Bonus amount actually earned by the Executive (if not yet paid), (iii) one hundred percent (100%) of the Executive’s Target Bonus (as defined below) for the year in which the
termination occurs, and (iv) a pro rata portion of the Executive’s Target Bonus based on the number of months worked during the year in which the termination occurs, subject to withholdings and deductions, which aggregate amount shall be
paid in a lump sum on the first regular payroll date following the effective date of the Executive’s release of claims; provided, however, the payment shall be made no later than March 15 of the year following the year of
termination; and 
 (ii) Provided that the Executive is eligible to continue coverage under a health, dental, or vision plan
sponsored by the Company under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) at the time of the Executive’s 

  
 3. 








 
termination and timely elects such continuation of coverage under COBRA, the Company will pay COBRA premiums on behalf of the Executive and his eligible dependents following the Executive’s
termination of employment (but in no event longer that the date on which the Executive or his eligible dependents cease to be eligible for COBRA). Notwithstanding the previous sentence, if the Company determines in its sole discretion that it cannot
provide the foregoing COBRA benefit without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), the Company shall in lieu thereof provide to the Executive a taxable monthly
payment in an amount equal to the monthly COBRA premium that the Executive would be required to pay to continue the Executive’s group health coverage in effect on the date of the Executive’s termination (which amount shall be based on the
premium for the first month of COBRA coverage), which payments shall be made regardless of whether the Executive elects COBRA continuation coverage and shall end on the earlier of (x) the date upon which the Executive obtains other employment
or (y) the last day of the twelfth (12th) calendar month following the Executive’s termination date. Upon the conclusion of such period of insurance premium payments made by the
Company, the Executive will be responsible for the entire payment of premiums required under COBRA for the duration of the COBRA period. No provision of this Agreement will affect the continuation coverage rules under COBRA, except that the
Company’s payment of any applicable insurance premiums will be credited as payment by the Executive for purposes of the Executive’s payment required under COBRA. Therefore, the period during which the Executive may elect to continue the
Company’s health, dental, or vision plan coverage at his own expense under COBRA, the length of time during which COBRA coverage will be made available to the Executive, and all other rights and obligations of the Executive under COBRA (except
the obligation to pay insurance premiums that the Company pays in accordance with the foregoing) will be applied in the same manner that such rules would apply in the absence of this Agreement. For purposes of this Section 7.2(ii),
(i) references to COBRA shall be deemed to refer also to analogous provisions of state law and (ii) any applicable insurance premiums that are paid by the Company shall not include any amounts payable by the Executive under an Internal
Revenue Code Section 125 health care reimbursement plan, which amounts, if any, are the sole responsibility of the Executive. 

(iii) Extension of the period of time for the Executive to exercise each of his then vested and outstanding Company stock options
until the earlier of (i) twelve (12) months after his termination date and (ii) the expiration date of each option as set forth in the applicable stock option agreement issued by the Company to the Executive; and 

(iv) Retention of the laptop computer, cellular phone and PDA provided to the Executive by the Company during his employment, provided
that the aggregate value of this Company property (as determined by the Company) is less than $3,000. 
 7.3 Termination without Cause or
Resignation for Good Reason Following a Change of Control. If the Company terminates the Executive’s employment without Cause, or the Executive resigns for Good Reason, in either case, at any time during the period commencing one
(1) month prior to the effective date of a Change of Control and ending thirty-six (36) months following the effective date of the Change of Control, and provided such termination constitutes a Separation from Service, then the Company
shall provide the Executive with the severance benefits described in Sections 7.2(i)-(iv) above. 

  
 4. 








 8. Section 409A. It is intended that all of the severance benefits and other payments
payable under this Agreement satisfy, to the greatest extent possible, the exemptions from the application of Code Section 409A provided under Treasury Regulations 1.409A-1(b)(4), 1.409A-1(b)(5) and 1.409A-1(b)(9), and this Agreement will be construed to the greatest extent possible as consistent with those provisions, and to the extent no so exempt,
this Agreement (and any definitions hereunder) will be construed in a manner that complies with Section 409A. For purposes of Code Section 409A (including, without limitation, for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii)), Executive’s right to receive any installment payments under this Agreement (whether severance payments, reimbursements or otherwise) shall be treated as a right to receive a
series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment. Notwithstanding any provision to the contrary in this Agreement, if Executive is deemed by the Company
at the time of Executive’s Separation from Service (as defined below) to be a “specified employee” for purposes of Code Section 409A(a)(2)(B)(i), and if any of the payments upon Separation from Service set forth herein and/or
under any other agreement with the Company are deemed to be “deferred compensation”, then to the extent delayed commencement of any portion of such payments is required in order to avoid a prohibited distribution under Code
Section 409A(a)(2)(B)(i) and the related adverse taxation under Section 409A, such payments shall not be provided to Executive prior to the earliest of (i) the expiration of the six-month period measured from the date of
Executive’s Separation from Service with the Company, (ii) the date of Executive’s death or (iii) such earlier date as permitted under Section 409A without the imposition of adverse taxation. Upon the first business day
following the expiration of such applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this paragraph shall be paid in a lump sum to Executive, and any remaining payments due shall be paid as otherwise provided
herein or in the applicable agreement. No interest shall be due on any amounts so deferred. 
 9. Release of Claims. Payment
and receipt of the severance benefits and/or accelerated vesting benefits provided for herein will be conditioned on Executive’s execution of a standard form of release in the form provided by the Company, within the time provided therein, and
such release must become effective in accordance with its terms, but in all cases the release must become effective within sixty (60) days following the date Executive’s “separation from service” (as defined under Treasury
Regulation Section 1.409A-1(h)). Such release shall include confirmation of Executive’s obligations under any confidentiality and/or proprietary information agreement. 

10. Definitions.  

(i) Cause. For purposes of this Agreement, “Cause” shall mean (i) Executive’s repeated unexplained or
unjustified absence from the Company or gross negligence, willful misconduct, or repeated, willful and flagrant insubordination in the performance of Executive’s duties to the Company as directed by the Board, which remains uncured more than
thirty (30) days following written notice from the Board of its belief that there is Cause for Executive’s termination under this clause (i); (ii) a material and willful commission of any federal or state felony; (iii) commission
of any act of fraud 

  
 5. 








 
that is related to Executive’s personal gain with respect to the Company; or (iv) conviction of a felony or a crime involving moral turpitude causing material harm to the standing and
reputation of the Company, or any willful violation of a Federal or State law that significantly reduces the credibility of the Company, or affects the Company in a materially financial way. No act or failure to act by Executive shall be deemed
“willful” if done or omitted to be done by Executive in good faith and with the reasonable belief that Executive’s act or omission was in the best interest of the Company or consistent with the Company’s policies or the directive
of the Board. 
 (ii) Change of Control. For purposes of this Agreement, “Change of Control” shall have the meaning
given to the term “Change in Control” as set forth in the Company’s 2003 Stock Option/Stock Issuance Plan in effect on the date hereof and as amended and/or restated from time to time. Notwithstanding the foregoing, if the Company or
a successor hereto subsequently determines that any benefits or other payments payable under this Agreement constitute deferred compensation under Section 409A, a “Change of Control” shall be limited to a transaction satisfying the
requirements of Treasury Regulation Sections 1.409A-3(c)(1) (regarding alternative payment schedules) and 1.409A-3(i)(5) (defining a change in control event, without regard to the alternative definitions thereunder). 

(iii) Good Reason. For purposes of this Agreement, “Good Reason” shall mean Executive’s
resignation of employment because any of the following occurs without Executive’s consent which remains uncured more than thirty (30) days following written notice from Executive to the Board specifying the basis for Executive’s
belief that Executive has Good Reason to resign: (i) the material diminution of Executive’s duties and responsibilities (such as the loss of oversight responsibility for research and development, marketing or sales components of the
Company’s operations, or Executive’s removal from or failure to be elected (or re-elected) to the Board prior to a Change of Control); (ii) the material reduction of Executive’s Base Salary or Annual Bonus potential, excluding
only reductions of 10% or less (cumulatively) that are made prior to a Change of Control in connection with an across-the-board reduction of all executive officers’ annual base salaries or bonus potential by a percentage at least equal to the
percentage by which Executive’s Base Salary or Annual Bonus potential is reduced; or (iii) the transfer of Executive’s principal place of business for the Company more than 40 miles from the Company’s current Santa Clara,
California location. If Executive resigns for Good Reason because of a material reduction in Executive’s Base Salary or Annual Bonus potential, Executive’s severance pay will be calculated using Executive’s Base Salary and Annual
Bonus percentage in effect immediately before such reduction. 
 (iv) Separation from Service. For purposes of this Agreement,
“Separation from Service” shall mean “separation from service” as defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternative definition thereunder. 

(v) Target Bonus. For purposes of this Agreement, “Target Bonus” shall be equal to the greater of
(i) Executive’s actual Annual Bonus amount paid for the prior calendar year, or (ii) the Annual Bonus percentage as provided in Section 2.2, or as most recently approved by the Board.
