Anti-A190 antibodies enable researchers to detect and measure the A190 antigen in biological samples. This target is a reported synonym of the POLR1A gene, which encodes RNA polymerase I subunit A. The human version of A190 has a canonical amino acid length of 1720 residues and a protein mass of 194.8 kilodaltons. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. Other names for this target antigen include AFDCIN and RPA1. Indicated applications for A190 antibodies listed below include ELISA, Western Blot, Immunocytochemistry, Immunoprecipitation, and Immunohistochemistry.
