General description

Dipeptidyl-peptidase 4 (DPP4; CD26; adenosine deaminase complexing protein-2) is a membrane glycoprotein with serine exopeptidase activity that cleaves X-proline dipeptides from the N-terminus of polypeptides. Inhibitors of DPP4 inhibit the degradation of glucose-dependent insulinotropic polypeptide and glucagon-like peptide-1 by DPP4 and have emerged as oral anti-diabetic agents.

Features and Benefits

Compatible with high-throughput handling systems.

Suitability

Suitable for the screening of inhibitors of DPP4.

Principle

The DPP4 Inhibitor Screening Kit is a simple assay suitable for high-throughput screening of potential DPP4 inhibitors. DPP4 activity is measured by cleaving the substrate to yield a fluorescent product (λex = 360/λem = 460 nm), proportional to the enzymatic activity present. The effectiveness of the test inhibitors may be compared with the DPP4 inhibitor (sitagliptin) provided as a control.

Two key enzymes like α-glucosidase and dipeptidyl peptidase-4 (DPP4) play an important role in the development of Type 2 diabetes (T2D), and inhibiting them is a common treatment strategy for T2D. In this study, an ultrafiltration- centrifugation approach was developed

Gamma-cyclodextrin (γCD) is a cyclic oligosaccharide consisting of eight α-(1,4)-linked glucopyranose subunits, which is often used in the food and pharmaceutical industries. However, little is known regarding the metabolic activity of "empty" γCD per se. Therefore, in the present study

Questions

1–2 of 2 Questions  

  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
