Anti-ARP9 antibodies enable researchers to detect and measure the ARP9 antigen in biological samples. This target is a reported synonym of the APOBEC3G gene, which encodes apolipoprotein B mRNA editing enzyme catalytic subunit 3G. This protein is known to function in innate immune responses, among other biological roles. The human version of ARP9 has a canonical amino acid length of 384 residues and a protein mass of 46.4 kilodaltons, although 2 isoforms have been identified. It is reported to be localized in the nucleus and cytoplasm of cells and notably expressed in many tissues, such as the fallopian tube, urinary bladder, and appendix. ARP9 is a member of the Cytidine and deoxycytidylate deaminase protein family. Western Blot is the most common application for the ARP9 antibodies listed below. ELISA and Immunohistochemistry are also common applications.
