Anti-CD44 Antibody

Manufactured by Antibodies.com, this affinity-purified polyclonal reagent is raised in rabbit against the CD44 antigen and is supplied as a 50 µl aliquot at a working concentration of 1 mg/mL. The immunogen is a synthetic peptide derived from human CD44 surrounding the non-phosphorylation site at serine706, and the antibody has been affinity-chromatography purified from rabbit antiserum using the epitope-specific immunogen to selectively enrich specific immunoglobulin. The product is unconjugated and formulated as a liquid in PBS containing 50% glycerol, 0.5% BSA, and 0.02% sodium azide, and it is intended for research use only — not for diagnostic or therapeutic applications. Recommended storage is at 4 °C for short-term handling, with aliquoting upon delivery and longer-term storage at –20 °C while avoiding repeated freeze/thaw cycles to preserve antibody integrity. Validated applications include Western blot (WB) and enzyme-linked immunosorbent assay (ELISA), and the antibody detects endogenous levels of CD44 protein across human, mouse, and rat samples, giving it broad cross-species utility for comparative studies. Its polyclonal nature provides multi-epitope recognition of the CD44 target, which can improve signal robustness in Western blotting of cell lysates and in ELISA-based quantification, and the unconjugated format offers flexibility for downstream labeling with HRP, fluorophores, or biotin depending on the experimental design. This reagent is dispatched by AFMS from St. Louis, Missouri, with a typical lead time of 6–9 business days.
