The Hieff Trans™ UltraProFect-CHO Transfection Reagent Kit is a highly efficient kit specifically designed for protein expression in CHO cells. It combines the powerful capability of rapid, ultra-high-yield transient protein production in suspension culture with the outstanding advantages of the Chinese Hamster Ovary (CHO) cell expression system. Built on high-density CHO cell culture, this kit features a transfection reagent meticulously engineered for high-density CHO suspension cultures, along with proprietary enhancers and culture medium additives, creating a synergistic effect that significantly boosts protein expression. This kit delivers highly efficient protein expression across a wide range of CHO cell lines (including ExpiCHO™, CHO-S, and CHO-K1). It performs exceptionally well in the production of complex proteins, such as full-length monoclonal antibodies, nanobodies, and bispecific antibodies. By markedly improving both expression efficiency and yield, it effectively meets the protein production demands of diverse applications. Features High Transfection Efficiency Advanced targeted delivery ensures high DNA uptake and protein yield in CHO cells. Broad Versatility Works with ExpiCHO, CHO-S, and CHO-K1 cells for full-length, nanobody, and bispecific antibodies. Scales linearly from shake flasks to bioreactors. Cost-Effective Delivers performance comparable to leading brands at low price. Specifications Cat.No. 40828ES80 Size 1000 mL Components Components No. Name 40828ES80 Component Cat.
