Detection principle

The kit uses a two-antibody two-step sandwich enzyme-linked immunosorbent assay (ELISA). Add standard and sample to be tested to pre-coated

Immunoglobulin AFc segment receptor I (FcαRI/CD89)

The transparent enzyme label is coated in the plate, and after incubation for a sufficient period of time, the unbound component is washed to remove the enzyme-labeled working solution, and after incubation for a sufficient period of time, the unbound component is washed and removed. Substrate A and B were sequentially added, and the substrate (TMB) was converted to a blue product under the catalysis of horseradish peroxidase (HRP), which turned yellow under the action of acid, and the color depth was in the sample.

Immunoglobulin AFc segment receptor I (FcαRI/CD89)

The concentration is positively correlated, the OD value is measured at a wavelength of 450 nm, and the sample is calculated according to the OD value of the standard and the sample.

2,

The specimens should be extracted as soon as possible after collection, and the extraction should be carried out according to the relevant literature. The experiment should be carried out as soon as possible after extraction. If it cannot be tested immediately,

Precautions】

1. The experiment is carried out in strict accordance with the operation of the manual. The determination of the experimental results must be based on the reading of the microplate reader.

2,

If the enzyme label is not used up after being opened, it should be immediately placed in a sealed bag and desiccant.

3,

4. Keep in mind that the sample has been diluted 5 times and the calculated result is multiplied by 5 to determine the actual concentration of the sample.

5, the kit quantitative

More than this

The range is calculated from the extension of the standard curve. If it is not used as an accurate quantitative result, please dilute it with a special dilution solution to determine the accurate result (

0.1-200ng/ml

Within the range), multiplying by the total dilution factor is the final concentration of the sample.

6. If the color is too light, the substrate incubation time can be extended appropriately.

7,

8. The kit is used during the shelf life. The reagents of different batches must not be mixed.

9. Substrate B is sensitive to light and avoids prolonged exposure to light.
