This kit is developed for titer detection of Anti-SARS-CoV-2 (BA.2) Antibody IgA (Spike RBD) in human serum.
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-Goat anti-Human IgA 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 calculate 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 IgA titer by Indirect-ELISA Assay.
Immobilized SARS-CoV-2 Spike RBD(BA.2) can bind Monoclonal Anti-SARS-CoV-2 Antibody, Human IgA in 1:200 human serum. Detection was performed using HRP-Conjugated Anti-human IgA antibody with sensitivity of 48 ng/mL (QC tested).
