Anti-CD79B Antibody

The Antibodies.com polyclonal antibody to CD79B (also known as Ig-beta or B29) is raised in rabbit and supplied as an unconjugated liquid reagent at 100 µl per vial. CD79B is a transmembrane signaling subunit of the B-cell receptor (BCR) complex, expressed throughout B-lineage development from the pro-B cell stage through mature B cells and frequently retained in B-cell-derived neoplasms. This reagent has been validated for western blot, immunohistochemistry, and immunofluorescence workflows, with reactivity confirmed against human, mouse, and rat samples. The polyclonal format provides recognition of multiple epitopes on the target, supporting detection across a range of expression levels in lymphoid tissue sections and prepared cell samples. Researchers commonly apply the antibody to characterize B-cell populations, profile lymphoma biopsy material, and study BCR signaling components in immunology research, where the unconjugated format allows flexible pairing with secondary reagents of the investigator's choice.
