Warn:
The stop solution contains dilute sulfuric acid, please do not touch it directly.
Assay Type:
Direct competitive
ELISA Kit Principle:
The ELISA kit uses direct competition ELISA to quantitatively detect 25-OH Vitamin D. The antigen in the sample to be tested will compete with 25-OH Vit D-peroxidase conjugate present for vitamin D binding protein (VDBP, Gc-globulin). After incubation and washing at a suitable temperature and a certain period of time, then TMD is added for the color reaction and the result is measured at 450 nm. The intensity of the color in the microplate is negatively correlated with the concentration of the analyte.
Cross Activity:
This ELISA kit specifically detects 25-OH Vitamin D and almost has no cross-reactivity to other compounds of similar structure.
Storage:
The ELISA kit should be stored at 2-8°C and should be performed at room temperature when used.
Notice:
In order to reduce the influence of various variables on the experimental results during the experiment, you must strictly control the experimental conditions, and the entire experimental operation process should be completed by the same person.
Precautions before Use:
Prepare the conjugate, substrate, buffer and stop solution. And before the test analysis, the reagents in the ELISA kit and the sample to be tested need to be incubated to room temperature.
Detection Method:
Colorimetric
Shipping Condition:
Ice packs
