Abstract
Methods are provided for improved production of hIL-3 either in glycosylated form from mammalian and yeast cells or in unglycosylated form from prokaryotes. Recombinantly produced human IL-3 is purified in a series of steps, initially employing hydrophobic interaction, followed by ion exchange chromatography and gel filtration.
