Description générale

Dipeptidyl peptidase-4 (DPP4), also known as CD26 and adenosine deaminase complexing protein 2, is a serine exopeptidase that cleaves X-Proline and X-Alanine residues from the N-termini of polypeptides.[1] DPP4 is a transmembrane glycoprotein whose activity regulates the bioactivity of multiple peptides such as growth factors, chemokines, and neuropeptides. DPP4 plays a major role in glucose metabolism via the regulation of glucagon-like peptide-1 and inhibitors of DPP4 are commonly used for the treatment of type 2 diabetes. DPP4 also plays an important role in immune regulation and may play a role in tumor suppression. Deletion of the DPP4 gene affects carbohydrate metabolism which in turn leads to mental retardation and hypotonia. Abnormal expression of the protein is observed during liver regeneration, cirrhosis and liver tumorigenesis.[2][3]

Application

DPP4 Activity Assay Kit has been used to determine the activity of dipeptidyl peptidase-4 (DPP4) in homogenates.[4][5]

Caractéristiques et avantages

Compatible with high-throughput handling systems.

Adéquation

Suitable for the measurement of dipeptidyl peptidase-4 (DPP4) in a variety of samples including tissue, cells and serum

Principe

The DPP4 Activity Assay kit provides a simple and direct procedure for measuring DPP4 activity in a variety of samples. In this assay, DPP4 cleaves a non-fluorescent substrate, H-Gly-Pro-AMC, to release a fluorescent product, 7-Amino-4-Methyl Coumarin (AMC) (λex = 360/λem = 460 nm). One unit of DPP4 is the amount of enzyme that will hydrolyze the DPP4 substrate to yield 1.0 μmole of AMC per minute at 37 °C.

Platelet-derived growth factor-B (PDGF-B) is a main factor to promote adipose tissue angiogenesis, which is responsible for the tissue expansion in obesity. In this process, PDGF-B induces the dissociation of pericytes from blood vessels; however, its regulatory mechanism remains unclear.

    1 answer

    1. The positive control in this kit is a recombinant human DPP4.

      Helpful?

  2. Hi, I purchased DPP4 Kit (MAK088) for testing pulse flour samples. The DPP4 assay buffer is limited in amount for hydrating pulse flour samples. Could I use 0.1M, pH8 Tris-HCl buffer instead? and what is the major component of your DPP4 assay buffer?

    1 answer

    1. The assay buffer supplied in Kit MAK088 is optimized for the reactions they are designed for. It is recommended to use the buffers in the kit. The components within the buffer are considered confidential and cannot be disclosed.

      Helpful?
