The LEU-16 ELISA kits listed below are analytical tools for measuring concentrations of LEU-16 in various samples. LEU-16 is an alternative name for the human MS4A1 gene, which encodes the protein, membrane spanning 4-domains A1. It has been mentioned that LEU-16 plays a role in B cell differentiation and receptor-mediated signaling pathways, among other functions. Structurally, the MS4A1 protein is 297 amino acid residues in length and 33.1 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the cell membrane of the cell. In terms of tissue specificity, it is noted to be expressed on B-cells. This protein is known to be phosphorylated. Other names for this target antigen include B1, Bp35, and CD20. Click on the following ELISA kits for more detailed information, including target reactivity and assay sensitivity.
