cGMP(Cyclic GMP) ELISA Kit

cGMP(Cyclic GMP) ELISA Kit
cGMP(Cyclic GMP) ELISA Kit
Product Code : E-EL-0083
Brand Name : Cyclic GMP
Product Description

Intended use

This ELISA kit can be applied to the in vitro quantitative determination of  cGMP 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 cGMP. During the reaction,  cGMP in the sample or standard competes with a fixed amount of cGMP on the solid phase supporter for sites on the Biotinylated Detection Ab specific to  cGMP. 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  cGMP in the samples is then determined by comparing the OD of the samples to the standard curve.

Specificity

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

Typical data

For convenience in result calculation, absorbance can be used as ordinate and standard concentrations as abscissa. The standard curve provided in the manual is only for reference, and experimenters should draw the standard curve based on data of themselves.
