Description

Fluorescein methotrexate is useful for studying antimetabolite resistance and spontaneous gene amplification.

Fluorescent probe for visualization of biochemical networks in living cells. It is used for studying antimetabolite resistance and spontaneous gene amplification. The quantitative binding of fluorescein methotrexate to dihydrofolate reductase (DHFR) enables researchers to isolate cells based on DHFR expression.
