Recombinant Human B-lymphocyte antigen CD20 (MS4A1) - VLPs (Active) | CBS-MP015007HU | Cusabio.
CUSABIO's product CSB-MP015007HU is a recombinant human B-lymphocyte antigen CD20-VLP (virus-like particle). It is produced by the expression of the DNA fragment corresponding to 1-297aa of the human CD20 protein in HEK293 cells. This full-length CD20 protein is fused with a 10xHis-tag at the C-terminus. It has been validated to be active. In the functional ELISA, this recombinant CD20 protein can bind to the anti-CD20 antibody. The EC50 is 3.243-7.085 ng/mL. As a VLP, this recombinant CD20 antigen is highly immunogenic and can induce an immune response similar to a natural infection but fail to replicate in the body. It can be used in cancer studies. And it is available now.
The CD20 antigen is a hydrophobic transmembrane protein expressed during B cell differentiation from the pro-B cell phase until the plasma cell stadium. It is therefore a marker for B cells. It is co-expressed on B cells with CD19. CD20 plays an essential role in the regulation of B-cell development and differentiation, B-cell receptor (BCR) signaling, and cell cycle initiation.
