Purity
> 95% by SDS-PAGE
Activity
Specific activity is 1.5-2.5 units/mL and was obtained by measuring the oxidation of NADPH in absorbance at 340 nm during reaction. One unit will convert 1.0 umole of 7,8 dihydrofolate and beta-NADPH to 5,6,7,8-tetrahydrofolate and beta-NADP per minute at
Quality Control Testing
Loading 3 ug protein in 15% SDS-PAGE
Storage Buffer
In 20 mM Tris-HCl buffer, 0.1 M NaCl, pH 8.0 (2 mM DTT, 30% glycerol).
Storage Instruction
Store at 2°C to 8°C for 1 week. For long term storage, aliquot and store at -20°C to -80°C.
Aliquot to avoid repeated freezing and thawing. -

HyperlinkGene Summary
Dihydrofolate reductase converts dihydrofolate into tetrahydrofolate, a methyl group shuttle required for the de novo synthesis of purines, thymidylic acid, and certain amino acids. While the functional dihydrofolate reductase gene has been mapped to chromosome 5, multiple intronless processed pseudogenes or dihydrofolate reductase-like genes have been identified on separate chromosomes. Dihydrofolate reductase deficiency has been linked to megaloblastic anemia. [provided by RefSeq
