애플리케이션

The kit is used for the detection of DHFR activity and screening of DHFR inhibitors. The assay is based on the ability of DHFR to catalyze the reversible NADPH-dependent reduction of dihydrofolic acid to tetrahydrofolic acid. The reaction progress is followed by monitoring the decrease in absorbance at 340 nm.
Dihydrofolic acid+NADPH+H+ ↔ Tetrahydrofolic acid+NADP+

생화학적/생리학적 작용

DHFR (dihydrofolate reductase) is an enzyme that catalyzes a reaction essential for the biosynthesis of nucleotidic bases of DNA. Blocking the enzyme causes cell death as a result of DNA synthesis inhibition. DHFR is an excellent target for anti-tumor drugs.

특징 및 장점

  • Quick and simple method.
  • The kit contains all the reagents required for a colorimetric assay of DHFR activity in cell lysates, tissue homogenates, or column fractions of purified enzyme.
  • The kit includes a purified enzyme for use as a positive control and screening of DHFR inhibitors.
  • The kit includes methotrexate (MTX), a prokaryotic and eukaryotic DHFR specific inhibitor, which exhibits anti-tumor activities.
  • The kit was tested on A431, NIH-3T3, and CHO cell lines, rat liver, kidney, brain, and skeletal muscle tissue extracts, and recombinant DHFR.

This work reports a detailed characterization of the antimicrobial profile of two trimethoprim-like molecules (compounds 1a and 1b) identified in previous studies. Both molecules displayed remarkable antimicrobial activity, particularly when combined with sulfamethoxazole. In disk diffusion assays on Petri dishes

Folic Acid Metabolism: A Role in Cancer's Cause and Cure

This article reviews some of our newest and most innovative technologies and their specific applications toward cancer research. It describes how complex the disease of cancer is, and how difficult it is to identify one topic that is completely unrelated to any other.

Folic Acid Metabolism in Cancer

This issue of Biofiles reviews some of our newest and most innovative technologies and their specific applications toward cancer research. In preparing this issue of Biofiles, one is reminded how complex the disease of cancer is, and how difficult it is to identify one topic that is completely unrelated to any other.
