Patent ID: 8470562

Claim:
A method of making a primary cell derived biologic, including the steps of: (a) removing contaminating cells from mononuclear cells (MNCs) by loading leukocytes onto lymphocyte separation medium (LSM), and washing and centrifuging the medium with an automated cell processing and washing system; (b) storing the MNCs overnight in a closed sterile bag system; (c) stimulating the MNCs with a mitogen and ciprofloxacin in a disposable cell culture system to produce cytokines; (d) removing the mitogen from the mononuclear cells by filtering; (e) incubating the filtered MNCs in a culture medium; (f) producing a clarified supernatant by filtering the MNCs from the culture medium; (g) producing a chromatographed supernatant by removing DNA from the clarified supernatant by anion exchange chromatography; and (h) removing viruses from the chromatographed supernatant by filtering with dual 15 nanometer filters in series, thereby producing a primary cell derived biologic, wherein the primary cell derived biologic comprises IL-1β, IL-2, and IFN-γ.
