Anti-ERT antibodies enable researchers to detect and measure the ERT antigen in biological samples. This target is a reported synonym of the ELF3 gene, which encodes E74 like ETS transcription factor 3. This protein is known to function in cell differentiation and extracellular matrix organization, among other biological roles. The human version of ERT has a canonical amino acid length of 371 residues and a protein mass of 41.5 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 bronchus and endometrium. Other names for this target antigen include EPR-1 and ESE-1. These ERT antibodies are widely used in Western Blot experiments, among other applications.
