Anti-Gpa1 antibodies enable researchers to detect and measure the Gpa1 antigen in biological samples. This target is a reported synonym of the CGA gene, which encodes glycoprotein hormones, alpha polypeptide. This protein is known to function in GPCR signaling pathways and the regulation of cell migration, among other biological roles. The human version of Gpa1 has a canonical amino acid length of 116 residues and a protein mass of 13.1 kilodaltons. It is reported to be a secreted protein that is notably expressed in the pituitary gland and placenta. Other names for this target antigen include CG-ALPHA and FSHA. ELISA is a widely used application for the Gpa1 antibodies listed below. In addition, Western Blot is also a common application.
