Anti-GRP49 antibodies enable researchers to detect and measure the GRP49 antigen in biological samples. This target is a reported synonym of the LGR5 gene, which encodes leucine rich repeat containing G protein-coupled receptor 5. This protein is known to function in GPCR signaling pathways and hair follicle development, among other biological roles. The human version of GRP49 has a canonical amino acid length of 907 residues and a protein mass of 100 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the Golgi and cell membrane of cells and notably expressed in many tissues, such as the bronchus and fallopian tube. Other names for this target antigen include FEX, FEX, and GPR49. Western Blot is a widely used application for the GRP49 antibodies listed below. In addition, ELISA is also a common application.
