Anti-Collybistin antibodies enable researchers to detect and measure the Collybistin antigen in biological samples. This target is a reported synonym of the ARHGEF9 gene, which encodes Cdc42 guanine nucleotide exchange factor 9. This protein is known to function in GPCR signaling pathways, among other biological roles. The human version of Collybistin has a canonical amino acid length of 516 residues and a protein mass of 61 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the cytoplasm of cells and notably expressed in many tissues, such as the bronchus, thyroid gland, and adrenal gland. This target antigen may also be known as DEE8. Indicated applications for Collybistin antibodies listed below include ELISA, Western Blot, Immunofluorescence, and Immunohistochemistry.
