Anti-SSP411 antibodies enable researchers to detect and measure the SSP411 antigen in biological samples. This target is a reported synonym of the SPATA20 gene, which encodes spermatogenesis associated 20. This protein is known to function in carbohydrate metabolism and homeostasis and cell differentiation, among other biological roles. The human version of SSP411 has a canonical amino acid length of 786 residues and a protein mass of 87.9 kilodaltons, although 4 isoforms have been identified. It is reported to be a secreted protein that is notably expressed in many tissues, such as the colon, testis, and adrenal gland.
