WebWithout hypoxanthine + thymidine: for use with dhfr selection system; Multiple formulas to optimize your protein-free applictions including adherent and suspension cells, with high proliferation rates and high protein yield; Directly convert cultures from adherent with serum to suspension without serum; Applications Recombinant protein expression WebDihydrofolate Reductase (DHFR) Dihydrofolate reductase is an enzyme that converts dihydrofolate to tetrahydrofolate and is involved in purines and thymidylate synthesis. It is encoded by the human DHFR gene. Antifolate drugs, methotrexate (MTX) and trimetrexate, can tightly bind to DHFR and inhibit DNA synthesis and cell proliferation.
