These thyrotrophic embryonic factor ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. thyrotrophic embryonic factor is an alias of the human TEF gene, which encodes the protein, TEF transcription factor, PAR bZIP family member. Notably, thyrotrophic embryonic factor is known to play a role in the regulation of transcription, among other functions. The TEF protein is 303 amino acid residues in length and 33.2 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus of the cell. Other names for this target antigen include thyrotroph embryonic factor, TEF, PAR bZIP transcription factor, and thyrotrophic embryonic factor.
