Anti-Fos Antibody

Manufactured by Antibodies.com, this affinity-purified polyclonal reagent was raised in rabbit against a synthetic peptide derived from human Fos, enabling sensitive detection of endogenous levels of the total Fos protein. The unconjugated antibody is supplied as a 50 µl aliquot at 1.0 mg/mL, formulated in phosphate buffered saline (pH 7.4, without Mg²⁺ and Ca²⁺) containing 150 mM NaCl, 0.02% sodium azide, and 50% glycerol, and was purified from rabbit antiserum by affinity chromatography using the epitope-specific immunogen. Validated for Western blot (WB) and immunohistochemistry (IHC), it cross-reacts with Human, Mouse, and Rat samples, making it a versatile tool for studies of immediate-early gene expression across standard laboratory models. The reagent is of the IgG isotype and is shipped at 4 °C; upon arrival it should be aliquoted and stored at −20 °C, with repeated freeze/thaw cycles avoided to preserve binding activity. Researchers seeking a robust rabbit-host primary antibody for Fos detection in western and tissue-staining workflows will appreciate the combination of broad species reactivity, defined formulation, and convenient storage profile offered by this Antibodies.com product.
