Page 2The descriptions of the following protocols are examples. Each user should determine the appropriate condition.

SDS-PAGE & Western blotting1) Mix the sample with equal volume of Laemmli’s sample buffer, then sonicate briefly (up to 10 sec.).
2) Boil the sample for 3 min. and centrifuge. Load 5 L (25 g) of the sample per lane in a 1-mm-thick SDS-polyacrylamide gel(12.5% acrylamide) for electrophoresis.
3) Blot the protein to a polyvinylidene difluoride (PVDF) membrane at 1 mA/cm2 for 1 hr. in a semi-dry transfer system(Transfer Buffer [25 mM Tris, 190 mM glycine, 20% methanol]). See the manufacturer's manual for precise transferprocedure.
4) To reduce nonspecific binding, soak the membrane in 10% skimmed milk (in PBS, pH 7.2) overnight at 4°C.
5) Incubate the membrane with primary antibody diluted with 1% skimmed milk (in PBS, pH 7.2) as suggested in theAPPLICATIONS for 1 hr. at room temperature. (The concentration of antibody will depend on the conditions.)
6) Wash the membrane with PBS-T [0.05% Tween-20 in PBS] (5 min. x 3).
7) Incubate the membrane with 1:10,000 of Anti-IgG (H+L chain) (Mouse) pAb-HRP (MBL; code no. 330) diluted with 1%
skimmed milk (in PBS, pH 7.2) for 1 hr. at room temperature.
8) Wash the membrane with PBS-T (5 min. x 3).
9) Wipe excess buffer on the membrane, and then incubate it with appropriate chemiluminescence reagent for 1 min.. Remove
extra reagent from the membrane by dabbing with paper towel, and seal it in plastic wrap.
10) Expose to an X-ray film in a dark room for 5 min. Develop the film as usual. The condition for exposure and development
may vary.

Immunohistochemistry for formalin fixed paraffin-embedded section1) Deparaffinize tissue sections in Xylene 3 times for 3 min. each.
2) Immerse the slides with Ethanol 3 times for 3 min. each, then wash the slides in PBS 3 times for 3 min. each.
3) Remove the slides from PBS and heat-treat with 10 mM Citrate buffer (pH 6.2) for 40 min. at 97°C using microwave oven.
4) Let the slide cool down until at room temperature in the Citrate buffer.
5) Remove the slides from the Citrate buffer and inactivate endogenous peroxidase with 3% H2O2 in Methanol for 10 min.
6) Wash the slides with PBST [0.25% Tween-20 in PBS] 3 times for 5 min. each.
7) Incubate the sections with 2.5% normal horse serum (Vectastain Universal Elite ABC Kit, Vector Laboratories; code no.
PK-7200) for 30 min. at room temperature to block non-specific staining. Do not wash.
8) Incubate the sections with primary antibody diluted with DAKO REAL Antibody diluent (Dako; code no. S2022) assuggested in the APPLICATIONS overnight at room temperature. (The concentration of antibody will depend on theconditions.)
9) Wash the slides 3 times in PBST for 5 min. each.
10) Incubate the sections with Biotinylated anti-mouse/rabbit IgG (Vectastain Universal Elite ABC Kit) for 30 min. at roomtemperature.
11) Wash the slides 3 times in PBST for 5 min. each.
12) Incubate the sections with ABC reagent (Vectastain Universal Elite ABC Kit). Incubate for 30 min. at room temperature.
13) Wash the slides 3 times in PBST for 5 min. each.
14) Visualize by reacting for 8 min. with Histofine Simplestain DAB Solution (Nichirei Biosciences; code no. 415171). *DAB isa suspect carcinogen and must be handled with care. Always wear gloves.
15) Wash the slides twice in PBS for 5 min. each.
16) Counterstain in hematoxylin for 5 min., wash the slides 3 times in water for 5 min. each, and then immerse the slides in PBS
for 5 min.
17) Dehydrate by immersing in Ethanol 3 times for 5 min. each, followed by immersing in Xylene 3 times for 3 min. each. Now
ready for mounting.
