Anti-BLK Antibody

A rabbit polyclonal IgG reagent from Antibodies.com targets BLK (B Lymphocyte Kinase), a Src-family non-receptor tyrosine kinase that contributes to B-cell receptor signaling and lymphoid development. The antibody is supplied as 200 µl of unconjugated antiserum, validated for Western Blot across Human, Mouse, and Rat sample types. BLK migrates at an apparent molecular weight of approximately 58 kDa, so standard SDS-PAGE gels followed by transfer to nitrocellulose or PVDF are well matched for resolving the target band. The polyclonal format presents multiple epitopes, which can help when probing full-length BLK or tracking endogenous expression under variable experimental conditions. Because the reagent is unconjugated, laboratories can pair it with HRP, biotin, or fluorophore-labelled secondary antibodies depending on the chosen detection chemistry. For storage, aliquot the antibody on arrival, refrigerate to preserve binding activity, and limit freeze-thaw cycles, which can otherwise reduce performance over time. Intended for research use only.
