Anti-SR-AII antibodies enable researchers to detect and measure the SR-AII antigen in biological samples. This target is a reported synonym of the MSR1 gene, which encodes macrophage scavenger receptor 1. This protein is known to function in cholesterol metabolism and homeostasis and cellular localization, among other biological roles. The human version of SR-AII has a canonical amino acid length of 451 residues and a protein mass of 49.8 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the membrane of cells and notably expressed in the spleen, placenta, lung, and bone marrow. Other names for this target antigen include CD204, CD204, and SCARA1. Flow Cytometry is the most common application for the SR-AII antibodies listed below. Western Blot and Immunohistochemistry are also common applications.
