特徴

• The Melatonin (MT) BioAssay™ ELISA Kit is a quantitative competitive assay for the detection of MT  in human serum, plasma and other biological fluids. Cell lysates and tissue homogenates, though not tested, may potentially be used as samples.
• Detection Range:7.813-500pg/ml
• Sensitivity:<4.688pg/ml
• Assay Principle:The microtiter plate provided in this kit has been pre-coated with MT. MT in the standard or sample competes with a fixed amount of plate-coated MT for antibody binding sites on the Antibody-Biotin reagent. Excess conjugate and unbound sample or standard are washed from the plate, after which Streptavidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. TMB substrate is then added to each well. The enzyme-substrate reaction is terminated by the addition of a sulfuric acid solution and the resulting color is measured spectrophotometrically at 450nm. The concentration of MT in the samples is determined by an inverse correlation between MT in the sample and the assay signal intensity.
