Anti-Gb5 antibodies enable researchers to detect and measure the Gb5 antigen in biological samples. This target is a reported synonym of the GNB5 gene, which encodes G protein subunit beta 5. This protein is known to function in GPCR signaling pathways, among other biological roles. The human version of Gb5 has a canonical amino acid length of 395 residues and a protein mass of 43.6 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the membrane of cells. Other names for this target antigen include HG2E and IDDCA. Indicated applications for Gb5 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
