BACKGROUND PRODUCT MS4A (membrane-spanning 4-domain family, subfamily A) is a large family Each vial contains 200 µg IgG in 1.0 ml of PBS with < 0.1% sodium azide of proteins that includes at least 26 members in mouse and humans. Flanked and 0.1% gelatin. by amino- and carboxyl- cytoplasmic regions, MS4A family members contain Blocking peptide available for competition studies, sc-109328 P, (100 µg four highly conserved transmembrane domains. CD20, the most well-known peptide in 0.5 ml PBS containing < 0.1% sodium azide and 0.2% BSA). MS4A family member, is a B-cell-specific molecule that functions as a calci - um-permeable cation channel and is known to accelerate the G to G pro - 0 1 APPLICATIONS gression induced by IGF-1.
