Fusionsproteiner, hvor ballastandelen består af peptider af interleukin 2, fremgangsmåde til deres fremstilling, deres anvendelse, genstruktur, der koder for et sådant fusionsprotein, vektor indeholdende en sådan genstruktur, og E. coli-celle indeholdende en sådan vektor.

摘要

Suitable as "ballast portion" for fusion proteins is a part of the amino-acid sequence of interleukin-2 (IL-2) which comprises considerably less than 100 amino acids. It is advantageous to start from a synthetic IL-2 gene which is divided by unique cleavage sites into six segments of which up to three can be linked in any desired sequence by the building block principle. Specific constructions allowing the solubility of the fusion protein to be varied are possible.
