293 cells｜Suspension culture｜Chemically defined & Serum-free medium

　HE200 medium is a chemically defined medium / serum-free medium optimized for the high production of recombinant proteins in human embryonic kidney (HEK) 293 cells, such as Expi293F, 293-F, HEK293, or 293T cells. The medium contains no proteins, hydrolysates, or components of animal and plant composition. All components have a known chemical structure.

HE200 medium has the advantages of lot-to-lot consistency and the ease of downstream purification after expression of recombinant proteins. The medium supports small- and large-scale protein expression in stably or transiently transfected 293 cells.

Protocol

・HE200 medium protocol

Figure 1) Growth assay of Expi293F cells in HE200 medium.
