2019-nCoV Neutralization Antibody Test kit (Colloidal Gold Immunochromatography) is used to qualitatively detect the 2019-nCoV neutralization antibodies in clinical samples (serum/plasma/whole blood).
The 2019-nCoV Neutralization Antibody Test Kit adopted Colloidal Gold Immunochromatography for measuring functional neutralizing antibodies to COVID-19. It is a rapid COVID-19 Neutralizing Antibody Test.
Immunocolloidal gold technique is a kind of technique that uses colloidal gold as a marker. This kind of special metal particle is hydrosol form of gold and it can bind proteins rapidly and stably. Moreover, colloidal gold has little effect on biological activity of natural proteins.
Used for qualitative detection of neutralizing antibodies to 2019-nCoV in clinical samples (serum/plasma/ whole blood).
The test kit contains colloidal gold labeled 2019-nCoV Spike Protein (RBD), mouse-anti human IgG antibody immobilized in G test area, mouse-anti human IgM antibody immobilized in M test area.
• Step 1
Add 20µl of whole blood sample/ 10µl of serum or plasma sample to well A.
• Step 2
Add two drops (about 80µl) of sample dilution to well B, and start timing.
• Step 3
The test results should be read at 15 mins. Do not read the results after 20 mins.
Purple red band appears in quality control area (C) and M/G test area.
Purple red band only appears in quality control area (C).
No purple stripe appears in the quality control area (C).
