Description

CD20, also known as MS4A1, is an activated-glycosylated phosphoprotein expressed on the surface of all B-cells beginning at the pro-B phase (CD45R+, CD117+) and progressively increasing in concentration until maturity. It is mapped to 11q12.2. This gene encodes a member of the membrane-spanning 4A gene family. The function of CD20 is to enable optimal B-cell immune response, specifically against T-independent antigens. It is suspected that CD20 acts as a calcium channel in the cell membrane. What�s more, this protein may be involved in the regulation of B-cell activation and proliferation.

Application Notes

Optimal dilution of the CD20 antibody should be determined by the researcher.

Immunogen

A human recombinant partial protein (amino acids M1-P297) was used as the immunogen for the CD20 antibody.

Storage

After reconstitution, the CD20 antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
