Listed are ELISA Kits for the detection of trans-acting transcription factor 8, an alias name of Sp8 transcription factor. The human protein, encoded by the gene SP8, is 490 amino acid residues long and has a mass of 48,674 daltons. However, there are up to 4 reported isoforms. It is a member of the Sp1 C2H2-type zinc-finger protein family. This protein is reported to have a nuclear cellular localization. This target may also be known as: transcription factor Sp8, and specificity protein 8.
