Anti-E1AF antibodies enable researchers to detect and measure the E1AF antigen in biological samples. This target is a reported synonym of the ETV4 gene, which encodes ETS variant transcription factor 4. This protein is known to function in keratinocyte differentiation and the regulation of transcription, among other biological roles. The human version of E1AF has a canonical amino acid length of 484 residues and a protein mass of 53.9 kilodaltons, although 3 isoforms have been identified. It is reported to be localized in the nucleus of cells and widely expressed in many tissue types. E1AF is a member of the ETS protein family. Immunohistochemistry is the most common application for the E1AF antibodies listed below. ELISA and Western Blot are also common applications.
