Anti-CSN1S1 Antibody

This rabbit polyclonal IgG reagent from Antibodies.com was raised against casein alpha-s1 (CSN1S1), a phosphorylated secretory protein that constitutes a major fraction of the casein micelle in murine milk. Supplied as 50 µL of unconjugated antiserum, the antibody is validated for Western blot detection of endogenous CSN1S1 in mouse mammary tissue, milk whey fractions, and cultured mammary epithelial cell lysates. Investigators studying lactation biology, milk protein expression, and dairy science benefit from the polyclonal format, which provides multi-epitope coverage across the mature casein alpha-s1 chain. The unconjugated presentation allows flexible pairing with HRP, biotin, or fluorophore-conjugated secondary reagents chosen to suit specific chemiluminescence or imaging workflows. Aliquot upon receipt to limit freeze-thaw cycles and preserve antibody activity across repeated blotting experiments.
