Anti-CVID5 antibodies are protein reagents that detect specific antigens. The CVID5 antigen is another term for the human protein membrane spanning 4-domains A1, encoded by the MS4A1 gene. The protein is known to function in B cell differentiation and receptor-mediated signaling pathways, among other biological roles. Canonically, it has an amino acid length of 297 residues and a mass of 33.1 kilodaltons. Its subcellular localization is in the cell membrane and it is noted to be expressed on B-cells. The CVID5 protein is a member of the MS4A protein family. Other alias names for CVID5 include B1, Bp35, and CD20. Indicated applications for CVID5 antibodies listed below include ELISA, Flow Cytometry, Western Blot, Immunocytochemistry, Immunofluorescence, Immunoprecipitation, and Immunohistochemistry.
