Abstract

Abstract Translated from German Mit Hilfe einer synthetischen DNA-Sequenz kann in einem gentechnologischen Verfahren Human-Interleukin-2 gewonnen werden. Das Gen wird vorteilhaft in Form mehrerer Fragmente synthetisiert, die enzymatisch zu größeren Teilsequenzen ligiert werden, weiche in Hybridplasmide eingebaut und in Wirtsorganismen amplifiziert werden. Nach Reisolierung der Teilsequenzen werden diese zum Gesamtgen vereinigt, in ein Hybridplasmid eingebaut und dieses in einem Wirtsorganismus zur Expression gebracht. With the help of a synthetic DNA sequence, human interleukin-2 can be obtained in a genetic engineering process. The gene is advantageously synthesized in the form of several fragments which are ligated enzymatically to larger partial sequences which are incorporated into hybrid plasmids and amplified in host organisms. After isolating the partial sequences, they are combined to form the entire gene, incorporated into a hybrid plasmid and expressed in a host organism.
