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.
