The kit is used for qualitative detection of 2019 NCOV neutralization
Antibodies in human serum, plasma and whole blood samples
As a new type, 2019 NCOV is a kind of NCOV. The main clinical symptoms of viral pneumonia are fever, fatigue and dry cough. Some patients have nasal congestion, runny nose, sore throat, diarrhea and other symptoms. In severe cases, dyspnea or hypoxemia occurred one week later, and acute respiratory distress syndrome, septic shock, metabolic acidosis and coagulation disorder occurred rapidly in severe cases.
There are several structural proteins in 2019 NCoV, including spike, envelope protein and membrane protein
(m) and nuclear cosid(n). Among them, spy protein contains receptor binding domain (RBD), which is involved in identifying angiotensin converting enzyme 2(ACE 2) on cell surface receptor. It is found that the peak rbd in 2019 ncov interacts strongly with human aceh 2 receptor, which leads to host cell endocytosis and virus replication in lung.
2019 NCoV infection or preventive vaccination will trigger an immune response and produce antibodies in the blood stream. Secreted antibodies can prevent virus infection. They exist in human circulation several months to several years after infection, and they are rapidly combined with pathogens in order to prevent virus replication. These antibodies are called neutralizing antibodies. Neutralizing antibody detection can determine whether people have the ability to resist virus infection.
The kit consists of a test card and a sample buffer.
Test card: It consists of aluminum foil package, desiccant, test strip and plastic card. The test paper consists of absorbent paper, cellulose nitrate film, sample pad, bonding pad and rubber plate. T-line (test line) of cellulose nitrate film is covered with bonding pad containing ACE 2 protein, C-line (QC-line), AB, R-line (reference-line), reference AB and marking 2019 NCOV AB.
Sample buffer: phosphate, sodium nitride, etc.
Hold at 2 ℃ ~ 30 ℃ and valid is set to 12 months.
The unsealing period of aluminum foil packaging is effective for 1 hour.
Lot number: see label.
Deadline: see detailed label
1. collected serum, plasma or whole blood samples.
2. Sediments and suspended solids in samples will affect the experimental results and must be removed by centrifugal separation.
Anticoagulant therapy: heparin, EDTA and sodium citrate are not important.
3. Blood collection shall be conducted by professional medical personnel. Serum/plasma testing is recommended. Patients' whole blood samples can also be used for rapid detection under emergency or special circumstances.
Serum and plasma samples shall not be stored for more than 8 hours at room temperature. They're right there
It can be stored at 2-8 C, 5 days C and 6 months C, but repeated freeze-thaw cycles must be avoided. Whole blood samples are not frozen and must be kept at 2℃ ~ 8℃ for more than 48 hours.
Please read the instructions carefully before testing. All reagents were restored to room temperature at room temperature.
1.Remove the test card from the packaging kit within one hour.
2.Add l sample (serum, plasma or whole blood) to the loading well, then add 2 drops (about 60 drops) to the μ test card, start the μ sample buffering, and start the timing.
3. The results were obtained after 10 ~ 15 minutes of reaction at room temperature, but the results were invalid after 20 minutes.
Test card result judgment chart
1. invalid result: the quality control line (c) is invalid and needs to be re-tested.
2. Negative results: the color of red stripe appears above or above the test line (T line), baseline (R line), quality control line (C line) and baseline line (R line).
3.Positive result: red band on test line (t), or the following red band on test line (t), instead of reference line (r), mass control line (c) and reference line (r).
1. The kit is not only used for qualitative detection, but also for auxiliary diagnosis in vitro.
2. Add a proper amount of samples in advance for testing. Too many or too small samples may lead to inaccurate results.
3.Hemolysis, blood lipid, jaundice and contaminated samples may affect the test results, so avoid these samples.
4.It should not be the only basis for clinical trials and treatments. The final diagnosis of the disease should be carried out after comprehensive evaluation of all clinical and experimental results.
