5-Methyltetrahydrofolaat ELISA Kit

Intra-assay Precision (Precision within an assay) : 3 samples with low, middle and high level 5-Methyltetrahydrofolate (5-Me-THF) were tested 20 times on one plate, respectively. Inter-assay Precision (Precision between assays) : 3 samples with low, middle and high level 5-Methyltetrahydrofolate (5-Me-THF) were tested on 3 different plates, 8 replicates in each plate. CV (%) = SD/meanX100 Intra-Assay: CV<10% Inter-Assay: CV<12%

All Species

5-Methyltetrahydrofolate is a methylated derivate of tetrahydrofolate. It is generated by methylenetetrahydrofolate reductase from 5,10-methylenetetrahydrofolate and used to recycle homocysteine back to methionine by 5-methyltetrahydrofolate-homocysteine methyltransferases (also called methionine synthases) .

ELISA Kit

Enzyme-linked Immunosorbent assay-Competitive

Colorimetric

This assay employs the competitive inhibition enzyme immunoassay technique. A monoclonal antibody specific to 5-Me-THF has been pre-coated onto a microplate. A competitive inhibition reaction is launched between biotin labeled 5-Me-THF analogues and unlabeled antigen (Standards or samples) with the pre-coated antibody. After incubation the unbound conjugate is washed off. Next, avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. The amount of bound HRP conjugate is reverse proportional to the concentration of 5-Me-THF in the sample. After addition of the substrate solution, the intensity of color developed is reverse proportional to the concentration of 5-Me-THF in the sample.
