Species enclosed in parentheses are predicted to react based on 100% sequence homology. Species cross-reactivity is determined by Western blot.
Specificity / Sensitivity
Bik Antibody detects endogenous levels of Bik protein. It does not cross-react with other Bcl-2 family members.
Source / Purification
Polyclonal antibodies are produced by immunizing rabbits with a synthetic peptide (KLH-coupled) corresponding to residues in the amino-terminus of Bik. Antibodies are purified by protein A and peptide affinity chromatography.
Western Blotting
Western blot analysis of extracts from HeLa, K562, HT-29 and HepG2 cells, using Bik Antibody.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human colon carcinoma, using Bik Antibody.
IHC-P (paraffin)
Immunohistochemical analysis of paraffin-embedded human lung carcinoma, showing cytoplasmic localization, using Bik Antibody.
Background
Bik/Nbk (Bcl-2-interacting killer/natural born killer) is a potent pro-apoptotic protein belonging to a group of Bcl-2 family members that includes Bad, Bid, Bim, Hrk, and Noxa, containing a BH3 domain but lacking other conserved domains, BH1 or BH2 (1,2). Functionally, Bik is able to bind to and antagonize anti-apoptotic Bcl-2 family members including Bcl-2, Bcl-xL, and viral homologs E1B-19K and EBV-BHFR1. The BH3 domain of Bik is essential for its apoptotic activity and interaction with survival proteins (3). Phosphorylation of Bik is correlated with an increase in its pro-apoptotic activity (4).
