Although the amino acid sequence of MDM2 predicts a protein with a molecular mass of approximately 54 kDa, MDM2 protein migrates on SDS/PAGE with an apparent mobility of 90 kDa.



Immunoblotting Protocol

MDM2 (Ab-1) can be used to detect MDM2 by Western blot of proteins previously separated by SDS/PAGE and electrophoretically transferred onto nitrocellulose membranes. The proteins are reacted with the monoclonal antibody and visualized using an HRP conjugated goat anti-mouse antibody with chemiluminescent detection.



Materials

Equipment:

? Electrophoresis apparatus

? Electroblotting apparatus

? Rocker platform



Solutions and Reagents

? Anti-MDM2 (Ab-1) Mouse mAb (IF2) Cat. No. OP46 or OP46T

? HRP conjugated goat anti-mouse IgG heavy and light chains (e.g. Cat. No. 401215)

? Chemiluminescence detection system

? ELB Buffer (include a cocktail of proetease inhibitors, such as 0.5 ?g/ml leupeptin, 1 ?g/ml pepstatin, 1 mM EDTA and 0.2 mM PMSF): 50 mM Hepes pH 7.0, 250 mM NaCl, 0.5 mM EDTA, 0.1% Nonidet P-40 Alternative

? SDS-PAGE (7% acrylamide)

? Phosphate buffered saline (PBS) pH 7.4; 1 Liter: 0.2 g KCl, 0.2 g KH₂PO₄, 8 g NaCl, 1.15 g Na₂HPO₄

? PBS/0.1% Tween^?-20 detergent (PBST)

? 3% Non-fat Dry Milk in PBST



Procedure

1. Lyse cells in ELB Buffer. (Alternatively, cells can be lysed in RIPA Buffer or directly into 1x Laemmli Sample Buffer).

2. Electrophorese 50-100 ?g lysate using a 7% acrylamide gel.

3. Transfer the protein samples from the polyacrylamide gel onto a nitrocellulose membrane using an electroblotting apparatus.

4. Block the membrane for 1 h in PBST containing 3% non-fat dry milk at room temperature with rocking. Use about 1 ml per cm²of membrane.

5. Incubate the membrane with 1 ?g/ml Anti-MDM2 (Ab-1) Mouse mAb (IF2) in 3% non-fat dry milk/ PBST for 1 h at room temperature with rocking.

6. Wash the membrane 3 times, 15 min each, in PBST at room temperature with rocking.

7. Incubate the membrane with HRP conjugated goat anti-mouse IgG heavy and light chain antibody, diluted according to the supplier’s instructions, in 3% non-fat dry milk/ PBST at room temperature for 1 h.

8. Wash the membrane 4 times, 15 min each, in PBST at room temperature with rocking.

9. Develop the membrane using chemiluminescent detection reagents according to manufacturer instructions.

10. Expose the membrane to film for ten minutes. Adjust subsequent exposure times as needed.
