Optimizing the Expression and Solubilization of an E. coli-Produced Leukemia Inhibitory Factor for Anti-LIF Antibody Production and Use Thereof for Contraception in Mice.

Abstract excerpt

Leukemia inhibitory factor (LIF) is an essential cytokine for blastocyst implantation. This study evaluated the effect of LIF inhibition on the blockage of embryo implantation. A truncated mouse LIF (tmLIF) was designed and expressed in E. coli. The protein expression was optimized using different culture media and inducers. To block pregnancy, the mice were immunized by the purified protein via maternal...
