Preparation and Storage
Background: TFF3
TFF3 (Trefoil Factor 3), also known as ITF and P1.B, is a peptide that plays an important role in epithelial regeneration and wound healing. It can form disulfide-linked dimers or associate into disulfide-linked complexes with the intestinal mucous proteins FCGBP and MUC-2. TFF3 is expressed by epithelial goblet cells in the respiratory tract, biliary and breast ducts, small and large intestine, and cardia of the stomach as well as by chondrocytes during bone development. TFF3 is upregulated in response to gastrointestinal epithelial disruptions and promotes epithelial wound healing. It enhances tumor cell invasion and metastasis by supporting hypoxia-induced VEGF upregulation.
Assay Procedure
Refer to the product- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 100 µL of Assay Diluent to each well.
- Add 50 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
- Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
- Add 200 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
- Aspirate and wash 4 times.
- Add 200 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
- Add 50 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
