Anti-C19orf59 antibodies enable researchers to detect and measure the C19orf59 antigen in biological samples. This target is a reported synonym of the MCEMP1 gene, which encodes mast cell expressed membrane protein 1. The human version of C19orf59 has a canonical amino acid length of 187 residues and a protein mass of 21.2 kilodaltons. It is reported to be localized in the membrane of cells and notably expressed in the spleen, lung, and bone marrow.
