生化/生理作用
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.
组分
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.
注意
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.
外形
Lyophilized from a 0.2 μm filtered solution in PBS, pH 7.4 with 50 μg BSA per 1 μg as a carrier protein.
制备说明
It should be reconstituted by adding sterile PBS containing 0.1% HAS or BSA to a concentration greater than 10 μg/mL.
分析说明
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.

Long recognized to be potent suppressors of immune responses, Foxp3(+)CD4(+) regulatory T (Treg) cells are being rediscovered as regulators of nonimmunological processes. We describe a phenotypically and functionally distinct population of Treg cells that rapidly accumulated in the acutely injured

IL-9 fate reporter mice established type 2 innate lymphoid cells (ILC2s) as major producers of this cytokine in vivo. Here we focus on the role of IL-9 and ILC2s during the lung stage of infection with Nippostrongylus brasiliensis, which results

Little is known about the expression and regulation of epiregulin (EREG) and amphiregulin (AREG) in ovarian follicles of large monoovulatory animal species. To characterize the gonadotropin-dependent regulation of EREG and AREG mRNAs in equine follicles prior to ovulation, extracts were
