Anti-CD19 Antibody

Manufactured by Antibodies.com as a primary antibody reagent, this rabbit polyclonal reagent is raised against CD19, a B-cell surface marker widely used to identify and characterize the B-lymphocyte lineage in research samples. The immunogen corresponds to a synthesized peptide derived from the internal region of human CD19, and the resulting antiserum is affinity-purified by epitope-specific affinity chromatography, yielding an unconjugated preparation that detects endogenous levels of CD19 protein. The antibody is supplied as 50 µl of liquid formulated in PBS containing 50% glycerol, 0.5% BSA, and 0.02% sodium azide at a concentration of 1 mg/ml, and it is validated for Western blot (WB) and ELISA applications on human samples. As a polyclonal reagent produced in rabbit and supplied without a fluorophore or enzyme label, it offers flexibility for downstream detection chemistries, while long-term stability is supported by storage at –20 °C for up to one year. Researchers investigating B-cell biology, lymphoma markers, or immunophenotyping workflows can rely on this Antibodies.com product for consistent detection of CD19 across the listed assay formats.
