CD20

Next Day 2-8°C

CD20 is a 33-37 kD transmembrane-spanning phosphoprotein that facilitates optimal B-cell immune response against T-independent antigens. It can exist in a complex with MHC class I, MHC class II, CD53, CD81, and CD82. However, CD20 can also form homo-oligomers. It has been suggested that homo-oligomerization of CD20 forms calcium ion channels in the plasma membrane of B cells. CD20 can be useful in diagnosing B-cell lymphomas and leukemias, and is the target of mAbs in the treatment of all B cell lymphomas, leukemias, and B cell-mediated autoimmune diseases. Interestingly, studies show a link between the immune system's B cells and diabetes mellitus in which anti-CD20 antibodies rendered the T cell antibodies dysfunctional and, hence, unable to cause insulin desensitivity by a B cell antibody-modulated autoimmune response.

This monoclonal antibody is aseptically packaged and formulated in 0.01 M phosphate buffered saline (150 mM NaCl) PBS pH 7.2 - 7.4 with no carrier protein, potassium, calcium or preservatives added. Due to inherent biochemical properties of antibodies, certain products may be prone to precipitation over time. Precipitation may be removed by aseptic centrifugation and/or filtration.

CD20 is present on human pre B lymphocytes and on B lymphocytes, except on plasma cells, and is expressed in tandem with surface IgM. It is also expressed in some follicular dendritic cells and at low levels on a T cell subset.
