The kit is used for qualitative detection of novel coronavirus (2019-nCoV) neutralizing antibody in human serum, plasma and whole blood samples.
Novel coronavirus (2019-nCoV) is a new coronavirus belonging to β genus. It can cause viral pneumonia, with fever, fatigue and dry cough as the main clinical manifestations, and a few patients with nasal congestion, runny nose, sore throat and diarrhea. In severe cases, dyspnea and/or hypoxemia occurred one week later. In severe cases, acute respiratory distress syndrome, septic shock, metabolic acidosis which is difficult to correct, bleeding and coagulation dysfunction, etc.
Novel coronavirus has several structural proteins, including spikes (S), envelopes (E), membranes (M) and nucleocapsids (N). The spike protein contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor angiotensin converting enzyme 2(ACE2). It is found that the RBD of 2019-nCoV spike protein interacts strongly with human ACE2 receptor, which leads to endocytosis of host cells in lung and virus replication.
After 2019-nCoV infection or vaccination, it will trigger an immune response and produce antibodies in the blood. Secreted antibodies can prevent virus infection, they will exist in the infected human circulatory system for several months to several years, and they will quickly and firmly combine with pathogens, thus preventing virus replication. These antibodies are called neutralizing antibodies. The detection of neutralizing antibody can judge whether people have the ability to prevent virus infection.
The kit consists of a detection card and a sample buffer solution.
Test card: It consists of aluminum foil bag, desiccant, test paper strip and plastic card. The test strip consists of absorbent paper, nitrocellulose membrane, sample pad, bonding pad and rubber plate. T line (detection line) of nitrocellulose membrane is coated with ACE2 protein, C line (quality control line) is coated with quality control line antibody, R line (control line) is coated with control antibody, and the binding pad contains 2019-nCOV antigen labeled by marker.
Sample buffer: phosphate, sodium azide, etc.
Keep it at 2℃ ~ 30℃ for 12 months.
The validity period of the aluminum foil bag is 1h after unpacking.
Batch number of products: see label for details.
Expiry date of products: see label for details.
1. Collect serum, plasma or whole blood samples.
2. Sediments and suspended solids in the samples may affect the experimental results and should be removed by centrifugation.
3. Anticoagulants: The use of heparin, EDTA and sodium citrate anticoagulants has no significant effect.
4. Blood collection should be carried out by professional medical personnel. It is recommended to give priority to serum/plasma detection. In emergency or special circumstances, whole blood samples of patients can also be used for rapid detection.
5. Serum and plasma samples should not be stored at room temperature for more than 8 hours, and can be stored for 5 days at 2℃ ~ 8℃, and for 6 months below -20℃, but avoid repeated freezing and thawing. Whole blood samples shall not be frozen and stored at 2℃ ~ 8℃ for no more than 48 hours.
Read the instruction manual carefully before testing. Please restore all reagents to room temperature before testing, and the testing should be carried out at room temperature.
1. Take out the test card from the packaged reagent bag and use it within 1 hour.
2. Drop 20μL sample (serum, plasma or whole blood) into the sample adding hole of the test card, then drop 2 drops (about 60μL) of sample buffer, and start timing.
3. Read the results when reacting for 10 ~ 15 minutes at room temperature. The reading result is invalid after 20 minutes.
Figure for judging test card results:
1. Invalid result: there is no reaction line in the quality control line (C line), and the test is invalid, so the experiment should be repeated.
2. Negative result: the detection line (T line) appears red band, and the color development is higher than or equal to that of the control line (R line), and the quality control line (C line) and the control line (R line) develop color.
3. Positive results: there is no red band in the detection line (T line) or red band in the detection line (T line), but the color development is lower than that of the control line (R line), and the quality control line (C line) and the control line (R line).
1.This kit is a qualitative test, and is only used for auxiliary diagnosis in vitro.
2. Please make sure that an appropriate amount of samples are added for testing. Too much or too little sample may lead to inaccurate results.
3. Hemolysis, lipidemia, jaundice and contaminated samples may affect the test results, so these samples should be avoided.
4. The test results of this reagent are for clinical reference only, and should not be used as the only basis for clinical diagnosis and treatment. The final diagnosis of the disease should be made after comprehensive evaluation of all clinical and laboratory results.
