These OCT3/4 ELISA kits are immunodetection tools for measuring the levels of OCT3/4 in biological samples. OCT3/4 is an alias of the human POU5F1 gene, which encodes the protein, POU class 5 homeobox 1. Notably, OCT3/4 is known to play a role in the morphogenesis of anatomical structure and the regulation of transcription, among other functions. The POU5F1 protein is 360 amino acid residues in length and 38.6 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is localized to the nucleus and cytoplasm of the cell. In terms of tissue specificity, it is reported to be expressed in developing brain. This protein is known to be ubiquitinated, sumoylated and phosphorylated. Other names for this target antigen include 45202, OTF-3, and OTF3.
