Abstract

original image

A new route to EPO: Nonglycosylated human erythropoietin (EPO) was prepared using a convergent chemical ligation synthetic strategy. The synthetic [Lysine24, 38, 83] EPO analogue, which was purified by HPLC and has the correct molecular weight (see picture), shows well-defined covalent structure, is correctly folded, and is biologically active in a factor-dependent cell line assay.
