Anti-Keratin 19 Antibody

Manufactured by Antibodies.com, this affinity-purified rabbit polyclonal reagent is raised against a synthesized peptide derived from human Keratin 19 (KRT19, also known as CK19) and is intended for the qualitative detection of endogenous total Keratin 19 protein in research samples. The antibody is supplied at 50 µL per vial as an unconjugated Rabbit IgG at a working concentration of 1.0 mg/mL, formulated in phosphate-buffered saline (without Mg²⁺ and Ca²⁺) at pH 7.4 with 150 mM NaCl, 0.02% sodium azide, and 50% glycerol as a cryoprotectant. Recommended applications include Western blotting (WB) and immunohistochemistry (IHC), with reactivity validated against human, mouse, and rat specimens. For routine handling, the antibody is shipped on cold packs at 4 °C and should be aliquoted upon arrival and stored long-term at −20 °C, with repeated freeze/thaw cycles avoided to preserve performance. Purified by affinity chromatography against the epitope-specific immunogen, this lot is offered for research use only and is not intended for diagnostic or therapeutic applications.
