- Description
| Specificity Profile | More Information |
 | The specificity of CD20 Monoclonal Antibody (CSB0019) was tested on the Membrane Proteome Array™ and shown to be specific for human CD20. The Membrane Proteome Array™ contains 6,000 different human membrane proteins, each expressed in unfixed human cells to ensure native conformation and post-translational modifications. The Membrane Proteome Array™ represents the industry standard for determining the binding specificity of antibodies and other protein ligands. |
| Application | Conditions | Recommended Concentration |
| Flow Cytometry, Extracellular | Live, Unpermeabilized | 1 µg/ml |
 | HEK-293F cells transiently transfected with human CD20 were stained with CD20 Monoclonal Antibody (CSB0019) (green) or isotype control antibody (gray), followed by AlexaFluor 647-conjugated anti-Mouse IgG secondary antibody. HEK-293F cells transiently transfected with an empty control vector were also stained with CD20 Monoclonal Antibody (CSB0019) (blue). | |

 | (A) JS-1 cells transiently transfected with human CD20 were stained with CD20 Monoclonal Antibody (CSB0019) followed by AlexaFluor 647 anti-Mouse IgG secondary antibody (red) and DAPI (blue). (B) JS-1 cells transiently transfected with an empty control vector stained with CD20 Monoclonal Antibody. (C) Isotype control: JS-1 cells transfected with human CD20 and stained with control MAb. | |

CD20 is a B-lymphocyte membrane protein that is part of the membrane-spanning 4A gene family. CD20 is involved in regulating calcium influx, which is important for the development and differentiation of B-cells into plasma cells. (NCBI Gene: 931, UniProtKB/Swiss-Prot: P11836). Other names: MS4A1, Bp35, FMC7, B1, LEU-16, CVID5, S7
