85-4643-58　［取扱停止］5-Me-THF (5-methyltetrahydrofolate) BioAssay™ ELISA Kit (Human) 96Tests　369690

特徴

• Sample Type:Serum, plasma and other biological fluids.
• Intended Use:Competitive ELISA, Coated with Antigen
• Sensitivity:<0.234ng/ml
• Range:0.319-25ng/ml
• Specificity:Human
• Test Principle:This BioAssay™ ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with 5-Me-THF. During the reaction, 5-Me-THF in the sample or standard competes with a fixed amount of 5-Me-THF on the solid phase supporter for sites on the Biotinylated Detection Antibody specific to 5-Me-THF. Excess conjugate and unbound sample or standard are washed from the plate, and HRP-Streptavidin (SABC) is added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by the addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm. The concentration of 5-Me-THF in the samples is then determined by comparing the O.D. of the samples to the standard curve.
