Anti-Slac-2a antibodies enable researchers to detect and measure the Slac-2a antigen in biological samples. This target is a reported synonym of the MLPH gene, which encodes melanophilin. This protein is known to function in intracellular protein transport, among other biological roles. The human version of Slac-2a has a canonical amino acid length of 600 residues and a protein mass of 65.9 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and widely expressed in many tissue types.
