Detection of Human Bcl‑2 Minus C-Terminus by Western Blot. Western blot shows lysates of KG‑1 human acute myelogenous leukemia cell line. PVDF membrane was probed with 0.1-0.5 µg/mL of Mouse Anti-Human Bcl‑2 Minus C-Terminus Monoclonal Antibody (Catalog # MAB827) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for Bcl‑2 Minus C-Terminus at approximately 24 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.
Detection of Human Bcl‑2 by Simple WesternTM. Simple Western lane view shows lysates of MCF‑7 human breast cancer cell line, loaded at 0.5 mg/mL. A specific band was detected for Bcl‑2 at approximately 24 kDa (as indicated) using 5 µg/mL of Mouse Anti-Human Bcl‑2 Minus C-Terminus Monoclonal Antibody (Catalog # MAB827). This experiment was conducted under reducing conditions and using the 12-230 kDa separation system.

Bcl-2 is a member of a family of proteins that regulates outer mitochondrial membrane permeability (1, 2). Bcl-2 is an anti-apoptotic member that prevents release of cytochrome c from the mitochondria intermembrane space into the cytosol. Bcl-2 is present on the outer mitochondrial membrane and is also found on other membranes in some cell types. Natural Bcl-2 contains a carboxyl-terminal mitochondria targeting sequence. Recombinant Bcl-2, missing the mitochondrial targeting sequence, maintains its ability to neutralize pro-apoptotic Bcl-2 family members. Neutralization by Bcl-2 appears to be through binding the BH3 region of pro-apoptotic Bcl-2 family members. This activity does not require the mitochondrial targeting sequence.
