Bad (Bcl2 Antagonist of Cell Death)
Description:
Bad is a 22kD protein that activates apoptosis. It exhibits sequence homology to Bcl-2, a protein that prevents apoptosis, within its BH1 and BH2 domains (1). Bad heterodimerizes with Bcl-Xl and Bcl-2 and reverses the apoptosis suppression effect by Bcl-Xl but not Bcl-2. Bad is phosphorylated by Raf-1, a serine-threonine kinase that is targeted to the mitochondrial membranes by Bcl-2 (2). In the presence of survival factor IL-3, Bad is phosphorylated on two serine residues within its 14-3-3 consensus binding sites. Phosphorylated Bad is then sequestered in the cytosol by binding to 14-3-3 and unable to heterodimerize with Bcl-Xl on mitochondrial membranes to promote apoptosis (3).

Applications:
Suitable for use in Western Blot and Immunohistochemistry. Other applications not tested.

Recommended Dilutions:
Western Blot (ECL): 1ug/ml
Immunohistochemistry: 1:50
Optimal dilutions to be determined by the researcher.

Positive Control:
Rat Brain Tissue Extract

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
