This kit is used to qualitatively detect novel coronavirus neutralizing antibodies in human serum, plasma, and whole blood samples.
Corona Beer is a novel coronavirus that is a long type. com Coronavirus. It can cause viral pneumonia, with the main clinical manifestations being fever, fatigue, and dry cough. A small number of patients also have symptoms such as nasal congestion, runny nose, sore throat, and diarrhea. Critical illness usually develops dyspnea and/or hypoxemia after one week and rapidly progresses to acute respiratory distress syndrome, septic shock, refractory metabolic acidosis, and coagulation dysfunction.
Infection or vaccination in the novel coronavirus of 2019 triggers an immune response and the production of antibodies in the blood. Secreted antibodies prevent viral infection. After infection, they will remain in the body's circulatory system for months to years, where they will quickly and firmly bind to the pathogen to prevent the virus from replicating. These antibodies are called neutralizing antibodies. Neutralizing antibody tests can determine whether a person is capable of preventing a viral infection.
Immunochromatography is used in the kit. The inspection card includes quality control line C, detection line T and reference line r. Detection of capillary samples (serum/plasma and whole blood) up-diffusion loading, binding and S-RBD manufacturing plates combined with immobilized ACE2 for NC membrane protein detection and signallocation line signaling. If a neutralizing antibody is present in the sample, it will bind to the labeled S-RBD antigen when it flows through the labeled S-RBD antigen. Neutralizing antibodies prevent S-RBD from binding to ACE2, resulting in a decrease in signal values that are inversely correlated with neutralizing antibody content. When the neutralizing antibody concentration is high enough, the T-rays are colorless. Whether the reference lines R and QC C are colored for the T line. Use quality control line c
If there is no color display on the C line, the test is invalid and the sample must be retested.
The kit consists of a test card and a sample buffer.
Test card: it is composed of aluminum foil bag, desiccant, test strip, plastic card. The test strip consists of absorbent paper, nitrocellulose film, specimen pad, bond pad and rubber sheet. The T line (detection line) of the nitrifying membrane covers the ACE2 protein, the C line (QC line) covers the Ab on the QC line, the R line (reference line) covers the reference Ab, and the pad contains the label 2019 nCoV Ab.
Sample buffers: phosphate, sodium azide, etc.
The storage temperature is 2 °C ~ 30 °C, and the validity period is 12 months.
The aluminum foil bag is valid for 1 hour.
Production batch number: See label for details.
Expiration date: See label for details.
1. Serum, plasma or whole blood samples are collected.
2. The precipitates and suspended solids in the sample will affect the experimental results and should be removed by centrifugation.
3. Anticoagulation: heparin anticoagulation, EDTA anticoagulation, sodium citrate anticoagulant effect is not obvious.
4. Blood collection should be carried out by a professional. Serum/serum/plasma tests are recommended. In urgent or exceptional circumstances, a patient's whole blood sample can also be used for rapid testing.
5. The storage time of serum and plasma samples at room temperature shall not exceed 8 hours.
It can be stored at 2-8 °C for 5 days and below -20 °C for 6 months, but repeated freeze-thaw should be avoided. Whole blood samples should not be frozen and should be stored at 2 °C to 8 °C for no more than 48 hours.
Read the operating instructions carefully before testing. All reagents should be returned to room temperature prior to testing, and testing should be performed at room temperature.
1. Remove the test card from the box and use it within 1 hour.
2. Add 20 L of sample (serum, plasma, or whole blood) to the filled well of the test card, add 2 drops (~60 L) of sample buffer, and then start timing.
3. React at room temperature for 10-15 min and then read the results. Invalid after 20 minutes.
Test Card Description:
1. Invalid result: The quality control line (c line) is invalid and needs to be retested.
2. Negative result: The appearance color of the detection line (T line) is higher than or equal to the reference line (R line), the quality control line (C line) and the reference line (R line).
3. Positive results: The red band can not see the test line (t line) or red band, the test line (t line) is lower than the reference line (R line), the quality control (c) line and the reference line (R line) are colored.
This kit is for qualitative analysis and is intended for in vitro diagnostics only.
2. Make sure to add an appropriate amount of sample for testing. Too much or too little sample size can lead to inaccurate results.
3. Hemolysis, blood lipids, jaundice, sample contamination, etc. may affect the test results and should be avoided as much as possible.
4. The test results of this reagent are for clinical reference only and shall not be used as the sole basis for clinical diagnosis and treatment. All clinical and laboratory results are combined to make a final diagnosis of the disease.
1. This product is only used for in vitro diagnostics.
2. This product is a disposable product and cannot be recycled.
3. Carefully read the instructions before operation, and carry out experimental operations in strict accordance with the reagent instructions.
4. Avoid experiments under harsh environmental conditions (including 84 disinfectants, sodium hypochlorite, acid, alkali, acetaldehyde and other high concentration corrosive gases, dust, etc.). Laboratory disinfection should be performed after the end of the experiment.
5. All samples and reagents used should be considered potentially infectious substances and disposed of in accordance with local regulations.
6. Reagents should be used within the validity period indicated on the outer packaging. The test card should be removed from the aluminum foil bag as soon as possible after removal to prevent moisture.
