Application:
Aminopterin (CAS: 54-62-6) is a folic acid antagonist. Its actively transported into cells by thefolate transporter. In the cell, its converted to a high molecular weight polyglutamate metabolite by folylpolyglutamate synthase, that, in turn, binds to dihydrofolate reductase and inhibits its activity. Suitable for cell culture. Antineoplastic, antirheumatic, folic acid antagonist.Sufficient Capacity: Sufficient facilities and technicians
OEM Package: Custom package and label available
