Anti-RAP74 antibodies enable researchers to detect and measure the RAP74 antigen in biological samples. This target is a reported synonym of the GTF2F1 gene, which encodes general transcription factor IIF subunit 1. This protein is known to function in transcription by RNA polymerase II, among other biological roles. The human version of RAP74 has a canonical amino acid length of 517 residues and a protein mass of 58.2 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 BTF4 and TF2F1. Western Blot is the most common application for the RAP74 antibodies listed below. ELISA, Immunofluorescence, and Immunohistochemistry are also common applications.
