products type :
ELISA Kit
products full name :
Human 25 Hydroxy Vitamin D ELISA Kit
products short name :
25 Hydroxy Vitamin D
products gene name :
25OHVD
specificity :
This assay has high sensitivity and excellent specificity for detection of 25OHVD. No significant cross-reactivity or interference between 25OHVD and analogues was observed. NOTE: cross-reactivity detection between 25OHVD and all the analogues, therefore, cross reaction may still exist in some cases.
storage stability :
Store all reagents at 2-8 degree C.

Intended Uses: This 25OHVD ELISA kit is a 1.5 hour solid-phase ELISA designed for the quantitative determination of Human 25OHVD. This ELISA kit for research use only, not for therapeutic or diagnostic applications!
products description :
Principle of the assay: 25OHVD ELISA kit applies the quantitative sandwich enzyme immunoassay technique. The microtiter plate has been pre-coated with a monoclonal antibody specific for 25OHVD. Standards or samples are then added to the microtiter plate wells and 25OHVD if present, will bind to the antibody pre-coated wells. In order to quantitatively determine the amount of 25OHVD present in the sample, a standardized preparation of horseradish peroxidase (HRP)-conjugated polyclonal antibody, specific for 25OHVD are added to each well to "sandwich" the 25OHVD immobilized on the plate. The microtiter plate undergoes incubation, and then the wells are thoroughly washed to remove all unbound components. Next, substrate solutions are added to each well. The enzyme (HRP) and substrate are allowed to react over a short incubation period. Only those wells that contain 25OHVD and enzyme-conjugated antibody will exhibit a change in color. The enzyme-substrate reaction is terminated by addition of a sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450 nm. A standard curve is plotted relating the intensity of the color (O.D.) to the concentration of standards. The 25OHVD concentration in each sample is interpolated from this standard curve.
