Description

Application

Aminopterin concentrate supplement for hybridoma cell culture applications.

Biochem/physiol Actions

Folic acid antagonist that binds to dihydrofolate reductase and inhibits its activity.

Folic acid antagonist. Aminopterin is actively transported into cells by the folate transporter. In the cell, it is converted to a high molecular weight polyglutamate metabolite by folylpolyglutamate synthase that, in turn, binds to dihydrofolate reductase and inhibits its activity. Aminopterin-polyglutamate is degraded intracellularly by γ-glutamyl hydrolase.

Preparation Note

Reconstitute contents of vial with 10 mL sterile cell culture medium. Stock solution is sufficient to prepare 500 mL medium. Final working concentration: 0.4 μM aminopterin.

Other Notes

More potent, but more toxic, than methotrexate.
