Precision
The precision is expressed by the coefficient of variation CV of the measured value of the sample. CV (%) = SD/mean×100
Intra-batch difference: Take the same batch of kits for quantitative detection of low, medium, and high value fixed value samples. Each sample is measured 20 times continuously, and the average value and SD value of samples of different concentrations are calculated.
Inter-batch difference: select 3 different batches of kits to quantitatively determine the low, medium, and high-value fixed value samples. Use the same kit for each sample to repeat the measurement 10 times, and calculate the average value and SD of samples with different concentrations. value.
Intra-run difference: CV<4.7%
Difference between batches: CV<7.8%
Recovery rate
The target protein of known concentration was added to 5 different samples, and the recovery experiment was performed to obtain the recovery range and average recovery rate.

Specificity
This kit recognizes natural and recombinant Goat substance P (SP) , and has no obvious cross-reactivity with other similar substances. Due to the limitation of technology and sample source, it is impossible to complete the cross-reaction test of all related or similar substances. Therefore, this kit may have cross-reaction with other untested substances.
Stability
It has been determined that the kit must be stored at the recommended temperature within the validity period, and the activity reduction rate is less than 5%. In order to reduce the influence of external factors on the detection value before and after the destruction of the kit, the environmental conditions of the laboratory should be kept as consistent as possible, especially the temperature, humidity and incubation conditions in the laboratory. Secondly, the operation by the same experimenter can reduce human error.

ELISA can be used to detect both antigens and antibodies. Samples to be tested usually include serum, plasma, cell supernatant, tissue homogenate, etc. Here are three necessary reagents in this assay method: 1. Antigen or antibody on solid phase, ie "immunosorbent"
2. Enzyme-labeled antibodies or antibodies, i.e. "conjugates";
3. Enzyme reaction substrate.
According to the source of the reagent, the nature of the sample, and the relevant conditions of the detection, a variety of detection methods
with different purposes can be designed.

Strict R&D and verification system to ensure product performance 1.carefully screened pairings In the double-antibody sandwich method, capture antibodies and detection
antibodies must pass strict screening, and then carry out scientific
concentration adjustment.
2. reliable specificity
By carefully selecting antibody pairs and optimizing buffers, matrix
effects are eliminated and only target analytes are recognized.
3. a variety of experimental principles
The double-antibody sandwich method, indirect method, and competition
method are designed to meet the detection of proxies with different
molecular weights.
4.The sample type has been verified
It can detect various samples such as serum, plasma,
culture supernatant, tissue, etc.
5. Good stability
6. Strict verification tests, including but not limited to the following
a.Intra-panel and inter-panel accuracyb.Authenticated samples, such as serum, plasma, cell supernatant and other natural sample analysis c.Blood component interference experiment d.Linear e.Recovery rate f.Reagents and components are stable These verification processes are reviewed by professional quality assurance personnel to ensure that the test results meet the guidelines and conform to the established technical specifications.

| ELISA stands for Enzyme-Linked,Immunosorbent Assay, also often referred to as Enzyme Immunoassay (EIA). ELISA, like other types of immunoassays, relies on antibodies and utilizes highly specific antibody-antigen interactions to detect the target antigen. ELISA is a classic experiment in immunology. Due to its high sensitivity, strong specificity and good repeatability, it has developed rapidly since it came out in the 1970s and is now widely used in many fields ,such as immune diagnosis, detection and biology. ELISA principle (see the picture on the right) |

Antigen-antibody immobilization
Known antigen/antibody binds to the bottom of the microtiter plate and maintains its immunological activity
Enzyme marking
Label antigen/antibody and maintain its immunocompetence and enzymatic activity
Substrate coloration
The substrate is catalyzed by the enzyme into a colored product, and the amount of the product is directly related to the amount of the substance to be tested in the sample, which can be
qualitatively or quantitatively analyzed according to the depth of the color Signal amplification
Due to the high catalytic efficiency of the enzyme, the results of the immune reaction are indirectly amplified, so that the assay method can achieve high sensitivity
