dihydrofolate reductase; Dihydrofolate reductase; dihydrofolate reductase; dihydrofolate reductase
products gene name :
DHFR
other gene names :
Dhfr; Dhfr; AA607882; AI662710; AW555094; 8430436I03Rik
uniprot entry name :
DYR_MOUSE
specificity :
This assay has high sensitivity and excellent specificity for detection of DHFR. No significant cross-reactivity or interference between DHFR and analogues was observed. NOTE: Limited by current skills and knowledge, it is impossible for us to complete the cross-reactivity detection between DHFR and all the analogues, therefore, cross reaction may still exist in some cases.
storage stability :
Store all reagents at 2-8 degree C.
other info1 :
Samples: Serum, plasma, Cell Culture Supernatants, body fluid and tissue homogenate. Assay Type: Competitive. Sensitivity: 0.1 ng/mL.
other info2 :
Intended Uses: This DHFR ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human DHFR. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
products description :
Principle of the assay: DHFR ELISA kit applies the competitive enzyme immunoassay technique utilizing a monoclonal anti-DHFR antibody and an DHFR-HRP conjugate. The assay sample and buffer are incubated together with DHFR-HRP conjugate in pre-coated plate for one hour. After the incubation period, the wells are decanted and washed five times. The wells are then incubated with a substrate for HRP enzyme. The product of the enzyme-substrate reaction forms a blue colored complex. Finally, a stop solution is added to stop the reaction, which will then turn the solution yellow. The intensity of color is measured spectrophotometrically at 450nm in a microplate reader. The intensity of the color is inversely proportional to the DHFR concentration since DHFR from samples and DHFR-HRP conjugate compete for the anti-DHFR antibody binding site. Since the number of sites is limited, as more sites are occupied by DHFR from the sample, fewer sites are left to bind DHFR-HRP conjugate. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The DHFR concentration in each sample is interpolated from this standard curve.

uniprot summary :
DHFR: Key enzyme in folate metabolism. Contributes to the de novo mitochondrial thymidylate biosynthesis pathway. Catalyzes an essential reaction for de novo glycine and purine synthesis, and for DNA precursor synthesis. Binds its own mRNA and that of DHFRL1. Defects in DHFR are the cause of megaloblastic anemia due to dihydrofolate reductase deficiency (DHFRD). DHFRD is an inborn error of metabolism, characterized by megaloblastic anemia and/or pancytopenia, severe cerebral folate deficiency, and cerebral tetrahydrobiopterin deficiency. Clinical features include variable neurologic symptoms, ranging from severe developmental delay and generalized seizures in infancy, to childhood absence epilepsy with learning difficulties, to lack of symptoms. Belongs to the dihydrofolate reductase family. Protein type: EC 1.5.1.3; Cofactor and Vitamin Metabolism - one carbon pool by folate; Cofactor and Vitamin Metabolism - folate biosynthesis; Oxidoreductase. Molecular Function: mRNA binding; dihydrofolic acid binding; RNA binding; dihydrofolate reductase activity; drug binding; oxidoreductase activity; NADP binding. Biological Process: tetrahydrofolate metabolic process; tetrahydrofolate biosynthetic process; nucleotide biosynthetic process; dihydrofolate metabolic process; response to methotrexate; one-carbon compound metabolic process; glycine biosynthetic process
