Characterization of human interferon-gamma and human interleukin-2 from recombinant mammalian cell lines and peripheral blood lymphocytes.


Journal Article

Human interleukin-2 (IL-2) and human interferon-gamma (IF-gamma) isolated from transfected heterologous cell lines were structurally compared with their natural counterparts isolated from peripheral blood lymphocytes (PBL). Several forms of IL-2 and IFN-gamma that were primarily due to differential glycosylation were produced by all cell types studied. Comparable molecular weights and sugar compositions were found for variants of natural and mammalian-derived recombinant IL-2, and variants of natural and mammalian-derived recombinant IFN-gamma. Furthermore, the specific biological activities of the natural and mammalian-derived recombinant lymphokines were similar and comparable to the specific activity of the Escherichia coli-derived recombinant proteins.
