Anti-ATOPY antibodies enable researchers to detect and measure the ATOPY antigen in biological samples. This target is a reported synonym of the MS4A2 gene, which encodes membrane spanning 4-domains A2. This protein is known to function in receptor-mediated signaling pathways and immune response pathways, among other biological roles. The human version of ATOPY has a canonical amino acid length of 244 residues and a protein mass of 26.5 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the tonsil, skin, and bone marrow. Other names for this target antigen include APY and FCER1B. Indicated applications for ATOPY antibodies listed below include ELISA, Flow Cytometry, Western Blot, and Immunohistochemistry.
