Anti-XPLN antibodies enable researchers to detect and measure the XPLN antigen in biological samples. This target is a reported synonym of the ARHGEF3 gene, which encodes Rho guanine nucleotide exchange factor 3. This protein is known to function in GPCR signaling pathways, among other biological roles. The human version of XPLN has a canonical amino acid length of 526 residues and a protein mass of 59.8 kilodaltons, although 4 isoforms have been identified. It is reported to be localized in the cytoplasm of cells. Other names for this target antigen include GEF3 and STA3. Indicated applications for XPLN antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
