This kit is developed for detecting SARS-CoV-2 Spike RBD in vaccine samples, which can meet the needs of vaccine developers to establish antigen quantification methods for preclinical evaluation, vaccine production and quality control, and realize accurate quantification of vaccine antigen contents for COVID-19 vaccines of all technological platforms, multivalent vaccines, and VOC-specific boosters.
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 6 simple steps:
a) All reagents were returned to room temperature(20°C-25°C) before use.
b) Add your sample to the plate, take the SARS-CoV-2 Spike RBD as Control sample. The samples and Control sample are diluted by Dilution Buffer.
c) Add a diluted Secondary antibody biotin-Anti-SARS-CoV-2 Spike RBD Antibody to the plate. The Secondary antibody is diluted by Dilution Buffer.
d) Add a diluted Streptavidin-HRP to the plate.
e) Wash the plate and add TMB or other colorimetric HRP substrate.
f) 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 protein bound.
This assay kit employs a standard sandwich-ELISA format providing a rapid detection of SARS-CoV-2 Spike RBD. The kit consists of pre-coated Anti-SARS-CoV-2 Spike RBD Antibody Microplate, SARS-CoV-2 Spike RBD as Control, biotin-Anti-SARS-CoV-2 Spike RBD antibody and HRP-Streptavidin. Detection is performed using HRP-Streptavidin with sensitivity of 12 pg/mL (QC tested).
