This kit is developed for serologic test for IgG4 titer of Anti-SARS-CoV-2 antibody in serum/plasma in vitro.
It is for research use only.
2. Find the expiration date on the outside packaging and do not use reagents past their expiration date.
3. The opened kit should be stored per components table. The shelf life is 30 days from the date of opening.
Your experiment will include 4 simple steps:
a) Add your sample to the plate, take the Anti-SARS-CoV-2 antibody as Control sample. The samples and Control sample are diluted by Dilution Buffer.
b) Add diluted Secondary antibody HRP-Mouse-Anti-Human IgG4 to the plate. The Secondary antibody is diluted by Dilution Buffer.
c) Wash the plate and add TMB or other colorimetric HRP substrate.
d) Stop the substrate reaction by add diluted acid. Absorbance (OD) is calculated as the absorbance at 450 nm minus the absorbance at 630 nm to remove background prior to statistical analysis. The OD Value reflects the amount of antibody bound.
Detection of Anti-SARS-CoV-2 Antibody, Human IgG4 titer by Indirect-ELISA Assay.
Immobilized SARS-CoV-2 Spike RBD can bind Monoclonal Anti-SARS-CoV-2 Antibody, Human IgG4 in 1:50 human serum. Detection was performed using HRP-Conjugated Anti-human IgG4 antibody with sensitivity of 4.9 ng/mL (QC tested).
