The recombinant protein is widely used in many fields of scientific research, diagnosis, treatment, food, etc., especially monoclonal antibodies (mAbs) are the fastest growing class of recombinant proteins in biotherapeutics in recent years. However, the problems of obtaining recombinant proteins with biological activities and increasing protein yields still plague the researchers from time to time.

GenCefe's protein production team is composed of technical experts with years of experience in protein expression and purification. With stable production capacity and in-house R&D capabilities, we can provide one-stop solutions from codon optimization,  gene synthesis , to protein expression and purification. GenCefe is committed to providing high-quality recombinant proteins to researchers around the world.

In addition to providing protein expression and purification services with four conventional expression systems of  bacterial ,  yeast ,  insect cell , and  mammalian cell , we have also developed a patented  cell free expression  technology, which is suitable for the production of difficult proteins such as toxic proteins and membrane proteins.
