생화학적/생리학적 작용

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.

성분

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.

주의사항

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.

물리적 형태

Lyophilized from a 0.2 μm filtered solution in PBS, pH 7.4 with 50 μg BSA per 1 μg as a carrier protein.

제조 메모

It should be reconstituted by adding sterile PBS containing 0.1% HAS or BSA to a concentration greater than 10 μg/mL.

분석 메모

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.

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

Seasonal and especially pandemic influenza predispose patients to secondary bacterial pneumonias, which are a major cause of deaths and morbidity. Staphylococcus aureus is a particularly common and deadly form of post-influenza pneumonia, and increasing staphylococcal drug resistance makes the development

Colonic enterocytes, like many epithelial cells in vivo, are polarized with functionally distinct apical and basolateral membrane domains. The aims of this study were to characterize the endogenous epidermal growth factor (EGF)-like ligands expressed in two polarizing colon cancer cell

The CCND1 gene, which is frequently overexpressed in cancers, encodes the regulatory subunit of a holoenzyme that phosphorylates the retinoblastoma protein. Although it is known that cyclin D1 regulates estrogen receptor (ER)α transactivation using heterologous reporter systems, the in vivo
