Abstract
A process for purifying IGF-I from variants of IGF-I is provided. In this process a mixture containing IGF-I and its variants is loaded onto a reversed-phase liquid chromatography column and the IGF-I is eluted from the column with a buffer at a pH of about 6-8. The buffer contains an alcoholic or polar aprotic solvent at a concentration of about 20-30% (v/v). This process can be preceded by a hydrophobic-interaction chromatography step.
