Anti-FEG-1 antibodies enable researchers to detect and measure the FEG-1 antigen in biological samples. This target is a reported synonym of the GPER1 gene, which encodes G protein-coupled estrogen receptor 1. This protein is known to function in GPCR signaling pathways and the cell cycle, among other biological roles. The human version of FEG-1 has a canonical amino acid length of 375 residues and a protein mass of 42.2 kilodaltons. It is reported to be widely expressed in many tissue types. Other names for this target antigen include CEPR, CMKRL2, and DRY12. Indicated applications for FEG-1 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
