Application

Methotrexate hydrate has been used:
  • as a dihydrofolate (DHFR) inhibitor in sphere forming assay culture
  • as a component of dulbecco′ modified Eagle′s medium (DMEM) for selection of transfected cells
  • in viability and co-culture assays

Potent inhibitor of dihydrofolate reductase and agent for antitumor studies. Use to inhibit dihydrofolate reductase in DHFR-based protein expression systems. Also effective in treatment of pyrimethamine-resistant Plasmodium vivax malaria parasites.
Potent inhibitor of dihydrofolate reductase and agent for antitumor studies. Use to inhibit dihydrofolate reductase in DHFR-based protein expression systems. Also shows immunosuppressive effects in, e.g., rheumatoid arthritis.
