This biosensor will be used to detect neutralizing antibodies to the new coronavirus (2019 ncov) in human serum, plasma and whole blood samples.
2019 Coronavirus disease Corona Beer 2019 (NCOV) β, Geiryu Net is a new coronavirus. It causes viral pneumonia. Clinical symptoms include fever, dullness, and dry cough, and some patients have symptoms such as stuffy nose, runny nose, sore throat, and diarrhea. Severe dyspnea and / or hypoxemia usually occur within a week. In severe cases, it progresses rapidly due to acute dyspnea syndrome, infectious shock, metabolic acidosis, and impaired bleeding function.
The novel coronavirus has many structural proteins such as s, E, m, and n. The mitotic spindle contains a receptor binding domain (RBD) that identifies the cell surface. Receptor angiotensin converting enzyme 2 (ACE 2). The 2019 ncov tattoo protein RBD was found to have a strong interaction with the human ACE2 receptor and induce viral replication in host cells and lungs.
novel coronavirus infections and vaccinations provoke an immune response and produce antibodies in the blood. Once infected, it stays in the circulatory system for months to years. It binds quickly and closely to pathogens to prevent viral replication. This antibody is called a neutralizing antibody. Neutralizing antibody tests can determine if people can prevent infections.
The kit consists of a test card and sample buffer.
Test card: Consists of aluminum foil bag, desiccant, test sheet and plastic card. It consists of an absorbent, a nitrocellulose membrane, a sample pad, a lining, and a rubber plate. The T line (inspection line) of the nitrocellulose membrane is coated with the ACE2 protein, the c line (quality control line) is coated with the antibody of the quality control line, and the R line (control line) is coated with a large group of antibodies. The set pad is coated with 2019 ncov antigen.
Sample buffer: phosphate, sodium azide, etc.
1. Collect serum, plasma or whole blood samples.
2. Precipitates and suspended matter in the sample affect the experimental results and must be removed by centrifugation.
3. Anticoagulant: The use of anticoagulants such as jellyfish skin, EDTA and sodium citrate has little effect.
4. Blood collection should be done by a medical professional. Priority is given to serum / plasma tests. In emergencies and special cases, the patient's entire blood sample can be used for rapid testing.
5. The storage time of serum and plasma samples at room temperature should not exceed 8 hours. It can be stored at temperatures between 2 ° C and 8 ° C for 6 months, 5 days or shorter, up to 20 ° C, but repeated freeze-thaw cycles should be avoided. The freezing time of whole blood specimens should be 48 hours to 8 ° C or less.
Please read the guide carefully before the exam. Allow all study agents to cool to room temperature before testing. The test should be conducted at room temperature.
1. Remove the test card from the test pack and use it within 1 hour.
Add the sample to the buffer solution (about 2 μl) and add the sample to the buffer solution (about 2 μl).
3. Reaction time at room temperature is 10 to 15 minutes. After 20 minutes, the result was invalid.
Result judgment chart of test card:
1. Invalid result: There is no response line on the quality control line (C line). The test is invalid and needs to be re-experimented.
2. Negative result: Red streaks appear on the test line (t line), and the color development rate is higher than that of the control line (r line), quality control line (C line), and control line (r line).
3. Positive result: There is no red belt in the test line (t line), or there is a red belt in the test line (t line), but the color development rate is lower than that of the control line (r line) and the quality is deteriorated. Control line (C line) and control line (r line).
1. This device is used only for in vitro diagnosis.
2. Appropriate amount of sample must be added to perform the test. Too many or too few samples will result in inaccurate results.
3. Hemolysis, blood fats, jaundice, and contaminated samples can affect test results and should be avoided.
4. Reagent test results are for clinical reference only and cannot be the sole basis for clinical diagnosis and treatment. The final diagnosis of this disease must be based on a comprehensive assessment of all clinical and laboratory results.
