Detection of Human BAK by Western Blot. Western blot shows lysates of Jurkat human acute T cell leukemia cell line, 293T human embryonic kidney epithelial cell line, and Daudi human Burkitt's lymphoma cell line. PVDF membrane was probed with 1 µg/mL of Mouse Anti-Human BAK Monoclonal Antibody (Catalog # MAB8161) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (Catalog # HAF007). A specific band was detected for BAK at approximately 23 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 2.
BAK in Jurkat Human Cell Line. BAK was detected in immersion fixed Jurkat human acute T cell leukemia cell line using Mouse Anti-Human BAK Monoclonal Antibody (Catalog # MAB8161) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to cytoplasm.

BAK (Bcl-2 homologous antagonist/killer; also know as BAK1 and Bcl-2-like protein 7) is a 25‑30 kDa member of the BCL-2 family of proteins. It is widely expressed and participates in the apoptotic cycle. BAK is an outer mitochondrial membrane protein that is inactive as a Zn-dependent homodimer. Upon activation by p53 or tBID, BAK oligomerizes, creating a pore in the mitochondrial membrane and allowing for cytochrome C release. Human BAK contains three Bcl-2 homology domains (aa 74‑88, 117‑136 and 169‑184), a Zn-binding region (aa 160‑166) and a C-terminal transmembrane segment (aa 188‑205). Amino acids 67‑94 mediate oligomerization of BAK. There are two potential isoform variants; one shows an alternate start site at Met 96, while a second shows a deletion of aa 46‑66. Over amino acids 20‑124, human BAK shares 76% aa identity with mouse BAK.
