SARS-CoV-2 Spike RBD (BA.4 & BA.5) ELISA Kit

The newly identified Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has posed a serious threat to human health. A rapid and effective assay kit detecting the levels of SARS-CoV-2 Spike protein is urgently needed to accelerate the development of COVID-19 vaccines.

This kit is developed for quantitative detection of SARS-CoV-2 Spike RBD (BA.4 & BA.5) in vaccine samples.

It is for research use only.

Please see Certificate of Analysis for details of reconstitution instruction and specific concentration.

1. Unopened kit should be stored at 2℃-8℃ upon receiving.

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.

This assay kit employs a standard sandwich-ELISA format, providing a rapid detection of SARS-CoV-2 Spike RBD. The kit consists of microplate pre-coated Anti-SARS-CoV-2 Spike RBD Antibody, an SARS-CoV-2 Spike RBD (BA.4&BA.5) as Control, an biotin-Anti-SARS-CoV-2 Spike RBD Antibody, HRP-Streptavidin and buffers.

Your experiment will include 5 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 HRP-Anti-SARS-CoV-2 Spike RBD Antibody to the plate. The diluted by Dilution Buffer.

d) Wash the plate and add TMB.

e) 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 protein bound.
