Recommended Protocol for Immunoblotting



Solutions and Reagents

•Transfer Buffer: 25 mM Tris base, 0.2 M glycine, 20% methanol, pH 8.5.

•SDS Sample Buffer: 62.5 mM Tris-HCl, pH 6.8, 2% SDS, 10% glycerol, 50 mM DTT, 0.1% bromphenol blue.

•10X TBS (Tris-buffered saline): To prepare 1 liter, 24.2 g Tris base, 80 g NaCl, adjust pH to 7.6 with HCl. Dilute 1:10 for use.

•Blocking Buffer: 1X TBS, 0.1% Tween^®-20 detergent with 5% non-fat dry milk.

•Primary Antibody Dilution Buffer: 1X TBS, 0.1% Tween-20 detergent with 5% BSA

•Wash Buffer (TBST): 1X TBS, 0.1% Tween-20 detergent



Blotting Membrane

Nitrocellulose or PVDF membranes may be used.



Protein Blotting

A general protocol for sample preparation using 2x10⁶ 293 cells per well in a 6-well plate is as follows:



1. Aspirate media. Treat cells by adding fresh media containing regulator for desired time.

2. Aspirate media from cultures; wash cells with PBS; aspirate.

3. Lyse cells by adding 100 µl of SDS Sample Buffer and immediately scrape the cells off the plate and transfer the extract to a microfuge tube. Keep on ice.

4. Sonicate for 2 s to shear DNA and reduce sample viscosity.

5. Heat sample to 95-100°C for 5 min. Cool on ice.

6. Microcentrifuge for 5 min.

7. Load 20 µl onto SDS-PAGE gel (10 cm x 10 cm).

8. Electrotransfer to nitrocellulose membrane.



As controls, we recommend using 20 µl lysate from UV treated HEK293 cell.



Membrane Blocking, Gel and Antibody Incubations

1. After transfer, wash membrane with 25 ml TBS for 5 min at room temperature.

2. Incubate membrane in 25 ml Blocking Buffer for 1-3 h at room temperature or overnight at 4°C.

3. Wash 3 times for 5 min each with 15 ml TBST.

4. Incubate membrane and primary antibody (at the appropriate dilution) in 10 ml Primary Antibody Dilution Buffer with gentle agitation overnight at 4°C.

5. Wash 3 times for 5 min each with 15 ml TBST.

6. Incubate membrane with conjugated secondary antibody at the appropriate dilution in 10 ml Blocking Buffer with gentle agitation for 1 h at room temperature.

7. Wash membrane as in step 5.
