Activity

Measured by its ability to inhibit Caspase-8-cleaved BID-mediated release of cytochrome c from isolated mouse liver mitochondria using the Rat/Mouse Cytochrome c Quantikine ELISA (Catalog # MCTC0) to quantify cytochrome c.
The typical EC50 is between 50 and 250 nM in the presence of 54 nM Recombinant Human BID Caspase-8-cleaved (Catalog # 882-B8).
Optimal dilutions should be determined by each laboratory for each application.

Background: Bcl-w

Bcl-w (also known as Bcl-2 like protein 2, BCL2L2) is a member of the Bcl-2 family of proteins that regulates outer mitochondrial membrane permeability (1, 2). Bcl-w is an anti-apoptotic member that prevents release of cytochrome c from the mitochondria intermembrane space into the cytosol. Bcl-w is required for normal sperm maturation (3, 4, 5). Natural Bcl-w contains a carboxyl-terminal mitochondria targeting sequence. Recombinant Bcl-w missing the mitochondrial targeting sequence maintains its ability to neutralize pro-apoptotic Bcl-2 family members. Neutralization by Bcl-w appears to be through binding the BH3 region of pro-apoptotic Bcl-2 family members. This activity does not require the mitochondrial targeting sequence.
