Product details:
Dipeptidyl peptidase IV (DPP4) Activity Assay Kit (Fluorometric) (ab204722) is an assay where DPP4 cleaves a substrate to release a quenched fluorescent group, AMC (7-Amino-4-Methyl Coumarin), which can be easily detected at Ex/Em = 360/460 nm. This assay is rapid, simple, sensitive, and reliable, as well as, suitable for high throughput activity screening of DPP4. This kit detects DPP4 activity as low as 3 uU per well.
DPP4 assay protocol summary:
- add samples and standards to wells
- add reaction mix
- analyze with microplate reader for 30 min in kinetic mode
Other Notes
This product was previously called K779 Biovision DPP4 Activity Fluorometric Assay Kit. Biovision was acquired by Abcam in 2021.
Dipeptidyl peptidase-4 (DPP4), also known as adenosine deaminase complexing protein 2 or CD26 (cluster of differentiation 26) is a protein that, in humans, is encoded by the DPP4 gene. The substrates of CD26/DPP4 are proline (or alanine) containing peptides and include growth factors, chemokines, neuropeptides, and vasoactive peptides. DPP4 plays a major role in glucose metabolism. It is responsible for the degradation of incretins such as GLP-1 and hence its inhibition by drugs such as Sitagliptin have been used for treatment of diabetes mellitus type 2. DPP4 also appears to work as a suppressor in the development of cancer and tumors.
The standard is affinity purified.

Dipeptidyl peptidase 4 also known as DPP4 or CD26 functions as a serine exopeptidase. This enzyme is involved in cleaving dipeptides from the N-terminus of polypeptides. DPP4 with a mass of approximately 110 kDa is expressed in various tissues such as the liver intestines kidney and lymphocytes. It exists in both a membrane-bound form and a soluble form in blood plasma.
Biological function summary
DPP4 plays a significant role in glucose metabolism and immune function. The enzyme interacts with members of the immune system and regulates proteins such as chemokines growth factors and neuropeptides. DPP4 acts independently and is not known to be part of a larger complex. It modulates biological processes by inactivating peptide hormones and signaling molecules which impacts glucose homeostasis and immune responses.
Pathways
DPP4 impacts the incretin signaling pathway and the immune response pathway. Incretin hormones like glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are substrates of DPP4 and play important roles in glucose metabolism. DPP4 also interacts with proteins such as adenosine deaminase (ADA) which impacts T-cell function and immune regulation. The regulation of these pathways by DPP4 influences metabolic and immune health.
DPP4 involvement is relevant in type 2 diabetes and immunological disorders. In type 2 diabetes DPP4 inhibitors modulate the incretin hormones improving glycemic control. Proteins like GLP-1 are affected by DPP4 activity connecting it to diabetes management. In autoimmune diseases altered DPP4 expression can impact immune cell functions influencing conditions such as rheumatoid arthritis. Through its effects on ADA and associated pathways DPP4 can influence both metabolic and immune-related disorders.
