This rabbit polyclonal antibody [1440] was generated against a synthetic peptide corresponding to residues 231-245 (SAEEKKEQTIEIKEE) of human CD20 fused to ovalbumin, and is specific for human CD20 (intracellular C-terminal region). Highlights: Reacts with intracellular residues 231-245 of human CD20Valuable for both pre-clinical and clinical research applicationsSuitable for Western Blot and Immunoprecipitation applications CD20, or B-lymphocyte antigen CD20, is a cell-surface protein expressed in most immune cells arising from the B-cell lineage and plays a role in cellular activation and proliferation. Importantly, CD20 is a recognized biomarker for a number of human disorders, including several autoimmune diseases and B-cell malignancies.
