SARS-CoV-2 Spike RBD (BA.4 & BA.5) Specific ELISA Kit (For Vaccine Development)

背景（Background）

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.

应用说明（Application）

This kit is developed for specific detection of SARS-CoV-2 Spike RBD (BA.4 & BA.5) 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 Omicron-specific boosters.

It is for research use only.

原理（Assay Principles）

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 with Anti-SARS-CoV-2 Spike RBD Antibody, an SARS-CoV-2 Spike RBD as Control, an biotin-Anti-SARS-CoV-2 Spike RBD Antibody, HRP-Streptavidin and buffers.

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 calc μLated as the absorbance at 450 nm minus the absorbance at 650 nm to remove background prior to statistical analysis. The OD Value reflects the amount of protein bound.
