Anti-FAK (Ab-843) Antibody

Offered through the Antibodies.com catalogue, this affinity-purified reagent is raised in rabbit and targets focal adhesion kinase (FAK) at the Ab-843 epitope, detecting endogenous levels of the total FAK protein in human samples. The polyclonal antibody is supplied as an unconjugated IgG preparation at a concentration of 1.0 mg/mL, packaged in a 50 µL volume, and is validated for Western blotting (WB) and immunohistochemistry (IHC) workflows. The immunogen is a synthetic peptide derived from an internal region of human FAK, and the antibody has been purified from rabbit antiserum by affinity chromatography using the epitope-specific immunogen to maximise specificity. The formulation is a phosphate buffered saline solution (without Mg²⁺ and Ca²⁺) at pH 7.4, containing 150 mM NaCl, 0.02% sodium azide as a preservative and 50% glycerol as a cryoprotectant. For routine handling the product is shipped at 4 °C; upon receipt it should be aliquoted and stored at −20 °C, with repeated freeze/thaw cycles avoided to preserve activity. Intended for research use only and not for diagnostic or therapeutic applications, this reagent provides a reliable tool for characterising FAK expression and signalling in human cellular and tissue-based studies.
