      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% bromophenol 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 HeLa 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 ml SDS Sample Buffer per well 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 ml onto SDS-PAGE gel (10 cm x 10 cm).
      8. Electrotransfer to nitrocellulose membrane.

      As controls, we recommend using 20 ml of HeLa cell extracts.

      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.

      DescriptionProtein A and immunoaffinity purified rabbit polyclonal antibody. Recognizes the ~36-38 kDa IκBα protein.
      BackgroundThe NF-κB/Rel transcription factors are present in the cytosol in an inactive state, complexed with the inhibitory IκB proteins. Activation occurs via phosphorylation of IκB-α at Ser32/36, resulting in the release and nuclear translocation of active NF-κB. IκB-α phosphorylation and resulting Rel-dependent transcription are activated by a highly diverse group of extracellular signals, including inflammatory cytokines, growth factors and chemokines. Phosphorylation of Ser32 and Ser36 has been shown to stimulate conjugation with ubiquitin followed by proteasome-mediated degradation of IκB, resulting in the release of active NF-κB.
