Product Description

Intended use

This ELISA kit can be applied to the in vitro quantitative determination of  PTD concentrations in serum, plasma and other biological fluids.

Test principle

This ELISA kit uses Competitive-ELISA as the method. The microtiter plate provided in this kit has been pre-coated with PTD. During the reaction,  PTD in the sample or standard competes with a fixed amount of PTD on the solid phase supporter for sites on the Biotinylated Detection Ab specific to  PTD. Excess conjugate and unbound sample or standard are washed from the plate, and Avidin conjugated to Horseradish Peroxidase (HRP) are added to each microplate well and incubated. Then a TMB substrate solution is added to each well. The enzyme-substrate reaction is terminated by adding Stop Solution and the color change is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The concentration of  PTD in the samples is then determined by comparing the OD of the samples to the standard curve.

Specificity

This kit recognizes PTD in samples. No significant cross-reactivity or interference was observed.

Linearity

Samples were spiked with high concentrations of Human ACTH and diluted with Reference Standard & Sample Diluent to produce samples with values within the range of the assay.
