DN feed series

DN feed 1+DN feed B

DN feed 1 is animal-free, protein-free, chemical-defined (CD) high-performance feed media, can be used for fed-batch culture of therapeutic protein product-producing Chinese hamster ovary (CHO) cells, through R&D to commercial manufacturing. DN feed 1 needs to be combined use with DN feed B, added to culture simultaneously.

DN feed 2+DN feed B2

DN feed 2 is animal-free, protein-free, chemical-defined (CD) high-performance feed media, can be used for fed-batch culture of therapeutic protein product-producing Chinese hamster ovary (CHO) cells, through R&D to commercial manufacturing. DN feed 2 needs to be combined use with DN feed B2, added to culture simultaneously.

How to use

We recommend to start adding feed media during middle-late stage of cell exponential growth stages, usually on day 3 when cell density reaches 2.0~3.0×10⁶ cells/mL, followed by add every other day with 3%±0.3%. Users can optimize the feed strategy based on the cell lines.

DNFeed Series can be used for cell lines using GS and dhfr screening systems, including CHO-K1, CHO-S, DG44, CHOZN and CHOK1SV.
