The ELISA kits listed below target DPP4, the symbol for the human gene, dipeptidyl peptidase 4, and a member of the Peptidase S9B family, DPPIV subfamily. The protein has an enzyme classification of dipeptidyl-peptidase IV. The protein encoded by DPP4 has a predicted amino acid length of 766, a mass of 88.3 kDa, and a membrane and secreted subcellular localization. Glycosylation has been reported. DPP4 may also be known by the following names: dipeptidylpeptidase 4, adenosine deaminase complexing protein 2, T-cell activation antigen CD26, DPP IV, and ADCP-2, and ADCP2. Orthologs of the gene, including human, mouse, rat, bovine, chicken, primate, guinea pig, plant, and other mammalian are available targets of several ELISA kits.
