Anti-CD20, N-Terminal [1439] Antibody

This rabbit polyclonal antibody [1439] was generated against a synthetic peptide corresponding to residues 25-41 (SGPKPLFRRMSSLVGPT) of human CD20 conjugated to ovalbumin, and is specific for the intracellular N-terminal region of human CD20.


  • Reacts with intracellular N-terminal residues 25-41 of human CD20
  • Valuable for both pre-clinical and clinical research applications
  • Suitable for Western Blot 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.

Western Blot of CD20 N and C-terminus

Western blots of human Ramos B-cells lysates probed with rabbit anti-CD20N (targeting the N-terminal residues 25-41) and rabbit anti-CD20C (targeting the C-terminal residues 231-245), pre-incubated with immunizing peptide (lanes 2 and 5), irrelevant peptide (lanes 3 and 6) or no peptide (lanes 1 and 4).
