Biochem/physiol Actions
Also known as keratinocyte autocrine factor (KAF); expression of amphiregulin mRNA has been found in numerous carcinoma cell lines and epithelial cells of several human tissues including colon, stomach, breast, ovary, and kidney.
Components
Human amphiregulin is produced by a DNA sequence that encodes a 98 amino acid residue form of mature human amphiregulin. This corresponds to amino acid residues 101-198 in E. coli. Amphiregulin is a glycoprotein produced in response to treatment of the cell line MCF-7, a human breast carcinoma cell line, with PMA, a protein kinase C activator and potent tumor promoter.
Caution
This product should be stored at -20°C. After preparation, the product can be stored at 2-8°C for one month, or frozen in aliquots at -20°C or -70°C for more extended storage.
Physical form
Lyophilized from a 0.2 μm filtered solution in PBS, pH 7.4 with 50 μg BSA per 1 μg as a carrier protein.
Preparation Note
It should be reconstituted by adding sterile PBS containing 0.1% HAS or BSA to a concentration greater than 10 μg/mL.
Analysis Note
Measured in a cell proliferation assay using Balb/3T3 mouse embryonic fibroblast cells. Marquardt, H. et al. (1984) Science 223:1079. The ED50 for this effect is typically 5-15 ng/mL.
