Listed are ELISA Kits for the detection of PU.1, an alias name of Spi-1 proto-oncogene. The human protein, encoded by the gene SPI1, is 270 amino acid residues long and has a mass of 31,083 daltons. However, there are up to 2 reported isoforms. It is a member of the ETS family. This protein is reported to have a nuclear cellular localization. For this target protein, ELISA kits with the following species reactivities are available: human, mouse, rat, bovine, chicken, primate, guinea pig, fish, and other mammalian. This target may also be known as: transcription factor PU.1, 31 kDa transforming protein, hematopoietic transcription factor PU.1, spleen focus forming virus (SFFV) proviral integration oncogene spi1, PU.1, SFPI1, and SPI-1.
