The antibody was affinity-purified from rabbit antiserum by affinity-chromatography using epitope-specific immunogen and the purity is > 95% (by SDS-PAGE).
Breast tumor kinase (Brk) is a non-receptor protein tyrosine kinase expressed in over 60% of breast carcinoma tissue samples and breast tumor cell lines. Brk is 80% identity to Sik (Src-related intestinal kinase) and exhibits the features of a novel non-receptor tyrosine kinase, including amino terminal SH3 and SH2 domains. Low levels of Brk transcripts have been identified in some human breast tumor cell lines but not in normal breast tissue.
