This HT-free formulation (without hypoxanthine and thymidine) has been specifically designed for applications involving DHFR-based selection and amplification systems, particularly with CHO-DG44 cell lines. The absence of HT allows efficient selective pressure during clone selection and maintenance while supporting strong productivity and stable culture performance. Suitable for fed-batch production processes, ForCHO® Medium without HT can be used together with ForCHO® Feed Alpha and Feed Beta to achieve high recombinant protein yields in demanding biomanufacturing applications.
This product corresponds to the medium previously marketed as First CHOice®.
• No change in formulation
• No change in raw materials
