Scientific Data Images for Human Bcl-w Antibody
Detection of Human Bcl-w by Western Blot.
Western blot shows lysates of WS-1 human fetal skin fibroblast cell line and CTLL-2 mouse cytotoxic T cell line. The PVDF membrane was probed with 1 µg/mL Human Bcl-w Monoclonal Antibody (Catalog # MAB824) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). For additional reference, Recombinant Human Bcl-w Minus C-Terminus (Catalog # 824-BW) (1 ng) was included. A specific band for Bcl-w was detected at approximately 18 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 9with 25 mM Tris and 0.15 M NaCl.Applications for Human Bcl-w Antibody

Background: Bcl-w
Bcl-w 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.
