背景介绍 EPO is predominantly synthesized and secreted by tubular and juxtatubular capillary endothelial and interstitial cells of the kidney. Approximately 10-15% of the total amount of Epo comes from extrarenal sources and is predominantly produced by hepatocytes and Kupffer cells of the liver. Approximately 40% of the molecular mass of Epo is due to its glycosylation. Glycosylation is an important factor determining the pharmacokinetic behavior of Epo in vivo. Non- glycosylated Epo has an extremely short biological half life. It still binds to its receptor and may even have a higher specific activity in vitro. 产品介绍 Recombinant EPO-a is a glycosylated disulfide-linked homodimeric protein consisting of 166 amino acid residues, and migrates as an approximately 35 kDa protein under reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human EPO mature chain was expressed in Chinese Hamster Ovary (CHO) cells.
