Anti-GAS antibodies enable researchers to detect and measure the GAS antigen in biological samples. This target is a reported synonym of the GAST gene, which encodes gastrin. This protein is known to function in GPCR signaling pathways, among other biological roles. The human version of GAS has a canonical amino acid length of 101 residues and a protein mass of 11.4 kilodaltons. It is reported to be a secreted protein that is notably expressed in the stomach. GAS is a member of the Gastrin/cholecystokinin protein family. Indicated applications for GAS antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
