The Hieff Trans™ UltraProFect-HEK293 Transfection Reagent Kit is a specialized transient transfection kit tailor-made for protein expression in HEK293 cells. Compatible with various 293 cell lines (including Expi293™, 293F, and HEK293), this all-in-one kit integrates the transfection reagent, culture medium, and feed supplement. It enables large-scale production of antigens, cytokines, antibodies, and complex recombinant proteins without the need for additional optimization. Features High Expression Yield Protein yield is 50% higher than leading brands. Comprehensive Optimization A fully integrated system (transfection reagent, medium, and feed) that requires no additional optimization. Scalability Designed specifically for suspension systems to facilitate seamless large-scale production. Broad Applicability Ideal for the expression of recombinant proteins, including antigens and antibodies.
