Anti-Bad (Bcl2 Antagonist of Cell Death)

Members in the Bcl-2 family are critical regulators of apoptosis by either inhibiting or promoting cell death (reviewed in 1 and 2). Bcl-2 homology 3 (BH3) domain containing pro-apoptotic proteins, such as Bax, Bid, and Bik, form a growing subclass of the Bcl-2 family. Another such protein is the Bcl-2-antagonist of cell death (Bad). Bad regulates apoptosis by forming heterodimers with anti-apoptotic proteins Bcl-2 and Bcl-xL, thereby preventing them from binding with Bax (3). Bad activity is regulated by its phosphorylation, it is inactivated by kinases such as Akt and MAP kinase and thus promotes cell survival (4), whereas JNK-induced phosphorylation promotes the apoptotic role of Bad (5). Applications: Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Western Blot: 0.5-1ug/ml, Immunohistochemistry: 2ug/ml, Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, add sterile glycerol (40-50%), aliquot and store at -20°C. Aliquots are stable for at least 12 months at -20°C. 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.
