Preparation and Storage
Background: Amphiregulin
Amphiregulin (AR) is an EGF family growth factor that is released as a soluble protein following proteolytic cleavage of its transmembrane precursor. Amphiregulin is expressed by numerous carcinoma cell lines and epithelial cells of the colon, stomach, breast, ovary and kidney. It acts through ErbB family of receptor to stimulate the proliferation of keratinocytes, mammary epithelial cells, fibroblasts, astrocytes and glial cells. Amphiregulin can also inhibit the growth of certain tumor cells.
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 50 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 cold Conjugate to each well. Cover with a new plate sealer, and incubate at 2-8 °C for 2 hours on the benchtop.
- 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.

FAQs
-
Assay Diluent RD1-14 contains visible precipitate. Is this acceptable to use?
A small amount of precipitate is expected and acceptable in Assay Diluent RD1-14. Variability has been observed between vials and diluent lots. It may not fully resolubilize but this will not impact assay performance. It is not recommended to filter the precipitate.
