Background
The trefoil factor (TFF) family contains three secreted, protease-resistant polypeptides that help to maintain gastrointestinal system integrity. Family members are 7-12 kDa in size, and contain a 3-disulfide bond generated trefoil structure that resembles a meadow clover. TFF1, 2 and 3 are produced in different areas of the digestive tract, and promote restitution, or the resealing of superficial wounds after injury.

What is the difference between the Quantikine and Duoset ELISA kits?
Our Quantikine kits are fully optimized and validated for the sample types listed on the product specific webpage and datasheet, as this can vary between kits. Each kit is supplied ready to use with one pre-coated 96-well plate, a detection antibody directly conjugated to HRP, and all other necessary reagents. These kits are ideal for researchers who want the convenience of a ready to use and optimized ELISA product. Some of these kits are also available prepackaged in larger 6 and 50 plate sizes.Our DuoSet Kits, in contrast, are ELISA development kits containing the capture and detection antibody, the mass-value calibrated standard, and streptavidin-HRP to prepare approximately 5 or 15 plates. Ancillary reagents will need to be used/purchased, and for most kits, we will recommend one of our Ancillary Reagent Kits, which contain the reagents we use ourselves in-house. DuoSet kits are validated only for cell culture supernatant samples and therefore require further development and validation for accurate measurement in more complex samples such as serum and plasma. Our DuoSet Kits offer an economical, flexible alternative for the experienced ELISA user.
