Anti-SMP30 antibodies enable researchers to detect and measure the SMP30 antigen in biological samples. This target is a reported synonym of the RGN gene, which encodes regucalcin. This protein is known to function in pathways of aging and the regulation of intracellular calcium, among other biological roles. The human version of SMP30 has a canonical amino acid length of 299 residues and a protein mass of 33.3 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and notably expressed in the pancreas, liver, duodenum, and adrenal gland. Other names for this target antigen include GNL, GNL, and HEL-S-41. Indicated applications for SMP30 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
