Anti-VIRG antibodies enable researchers to detect and measure the VIRG antigen in biological samples. This target is a reported synonym of the VIPR1 gene, which encodes vasoactive intestinal peptide receptor 1. This protein is known to function in receptor-mediated signaling pathways and GPCR signaling pathways, among other biological roles. The human version of VIRG has a canonical amino acid length of 457 residues and a protein mass of 51.5 kilodaltons, although 5 isoforms have been identified. It is reported to be localized in the cell membrane of cells and widely expressed in many tissue types. Other names for this target antigen include HVR1, II, and PACAP-R-2. Western Blot is a widely used application for the VIRG antibodies listed below. In addition, ELISA is also a common application.
