摘要: An interleukin-2 preparation suitable for pharmaceutical purposes, consisting essentially of disialilated glycosylated interleukin-2, monosialilated glycosylated interleukin-2, or a mixture thereof, and substantially free of organic solvents, is isolated from recombinant CHO cells transformed with a vector containing a DNA sequence coding for a natural precursor of human interleukin-2, and is purified by a multi-step process.
