Anti-OCT4-PG1 antibodies enable researchers to detect and measure the OCT4-PG1 antigen in biological samples. This target is a reported synonym of the POU5F1B gene, which encodes POU class 5 homeobox 1B. This protein is known to function in the regulation of transcription, among other biological roles. The human version of OCT4-PG1 has a canonical amino acid length of 359 residues and a protein mass of 38.6 kilodaltons. It is reported to be localized in the nucleus of cells. This target antigen may also be known as OCT4-PG1.
