SARS-Cov-2 Neutralising Antibody Kits
When someone contracts COVID-19, the host’s immune response can be measured by the presence of neutralising antibodies. Neutralising antibodies prevent the interaction between SARS-CoV-2 virus and receptors on human cells, giving the patient immunity.
Neutralising antibody detection is therefore very important in understanding and treating COVID-19. For example, to:
Test neutralising antibody induction during vaccine development, and how long antibodies are present for after infection
Confirm COVID-19 patient immunity
Allow donor selection in convalescent plasma therapy (using the antibodies of immune patients to help patients with active COVID-19)
Identify compounds that can interfere with the mechanism of viral infection, to prevent or treat COVID-19
Rapid immunity evaluation within 25 mins.
Proved by clinical evaluation with subjects who received vaccine.
Compatible with serum, plasma, whole blood, and fingertip blood.
Compatible with optical reading device for POC.
SUMMARY AND EXPLANATION
The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.
PRINCIPLE OF THE TEST
This test uses double-antibody sandwich to legally detect the antigen of novel coronavirus (2019-nCoV) in saliva samples. During detection, the gold labeled anti-2019-nCoV monoclonal antibody in the labeling pad binds to the 2019-nCoV antigen in the sample to form a complex, and the reaction complex moves forward along the nitrocellulose membrane under the action of chromatography, it is captured by the anti-2019-nCoV monoclonal antibody pre-coated by the detection zone (T) on the nitrocellulose membrane, and finally a red color reaction line is formed in the T zone. If the sample does not contain 2019-nCoV antigen, a red color reaction line cannot be formed in the T zone. Regardless of whether the sample to be tested contains 2019-nCoV antigen, a red reaction line will always form in the quality control area (C).

2019-nCoV RBD Antibody Rapid Test is an immunochromatographic assay for rapid, qualitative detection of the novel coronaviruses (2019-nCoV) spike protein receptor-binding domain (RBD) antibodies in human fingerstick whole blood, venipuncture whole blood, serum or plasma specimen.
The Test is used to monitor the presence of 2019-nCoV RBD antibodies in subjects vaccinated with the novel coronavirus vaccine or in people infected with the novel coronavirus.
2019-nCoV RBD Antibody Rapid Test can be used to assess vaccine efficacy after vaccination or whether 2019-nCoV RBD antibodies are produced in human body after infection with novel coronavirus.
For in vitro diagnostic use only.

SUMMARY AND EXPLANATION
The novel coronaviruses belong to the β genus. COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently, the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source.
The genome of coronavirus encodes four structural proteins, namely Nucleoprotein, small membrane protein, membrane protein and Spike protein (S protein). The virus receptor-binding domain (RBD) is an important domain in Spike protein and is the main structural domains for inducing neutralizing antibodies and T-cell immune responses. The viral spike protein binds the host receptor angiotensin-converting enzyme 2 (ACE2) via the receptor-binding domain (RBD), and thus is believed to be a major target to block viral entry. Neutralizing antibodies that had receptor binding motif of RBD compete strongly with human ACE2.
PRINCIPLE OF THE TEST
2019-nCoV RBD Antibody Rapid Test is based on the principle of double antigen sandwich immunoassay for determination of 2019-nCoV RBD antibodies in human whole blood, serum and plasma specimen.
During detection, When the 2019-nCoV RBD antibodies level in the specimen is at or above the detection limit of the test, the RBD antibodies bound to the colloidal gold labeled 2019-nCoV recombinant antigen and form an immune complex which are captured by RBD immobilized in the Test Region (T) of the nitrocellulose membrane, and this produces a colored test band that indicates a positive result. When the 2019-nCoV RBD antibodies level is zero or below the detection limit, there is no visible colored band in the Test Region (T) of the device. This indicates a negative result.
To serve as a procedure control, a colored line will appear at the Control Region (C), if the test has been performed properly.
MATERIALS AND COMPONENTS

Materials may require but not provided
- Transfer pipette
STORAGE AND STABILITY
- Store at 2°C - 30°C in the sealed pouch up to the expiration date printed on the package, forbidden to store under 2°C and avoid using expired products.
- The test cassette is used within 15 minutes after taking out from the foil envelope. Buffer solution are re-capped in time after use.

The test can be performed with fingerstick whole blood, venous whole blood, serum and plasma.
For Fingerstick Whole Blood:
1. Clean the area to be lanced with an alcohol pad. Allow the finger to dry thoroughly.
2. Use a sterile lancet, puncture the skin just off the center of the finger pad. Apply gentle pressure beside the point of the puncture. Wipe away the first drop of blood.
3. Collect a fingerstick whole blood specimen using a blood collection tube with suitable anticoagulant (containing EDTA or Heparin). Other anticoagulants have not been validated and may give incorrect result.
4. If blood flow is inadequate, the subject’s finger may have to be gently massaged at the finger base to produce several droplets of sufficient volume.
5. Draw 20μL of fingerstick whole blood from the blood collection tube with the disposable dropper. Whole blood specimen collected by fingerstick should be tested immediately.
For Venous Whole Blood:
1. According to standard venous blood collection procedure, collect a venipuncture whole blood specimen using a blood collection tube with suitable anticoagulant (containing EDTA or Heparin). Other anticoagulants have not been validated and may give incorrect result.
