Human Anti-SARS-CoV-2 (XBB.1.5) Antibody IgG Titer Serologic Assay Kit (Spike RBD)

组分（Materials Provided）

产品概述（Product Overview）

Since December 2019, the emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and its associated disease, COVID-19, has caused a devastating pandemic worldwide.As the virus spreads globally, the continuous emergence of new mutant strains escalated the challenge on humans.To facilitate the mutant-related research, drug trials and vaccine development, a high-throughput assay to measure IgG antibodies against the mutants is in urgent need.

应用说明（Application）

The kit is developed for titer measurement of Anti-SARS-CoV-2 (XBB.1.5) IgG antibody (Spike RBD) in human serum.

It is for research use only.

存储（Storage）

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.

原理（Assay Principles）

This assay kit employs a standard indirect-ELISA format, providing a rapid detection of Anti-SARS-CoV-2 antibodies in serum by SARS-CoV-2 Spike RBD (XBB.1.5). The kit consists of Pre-coated SARS-CoV-2 Spike RBD (XBB.1.5) Microplate, an Positive Control, an Negative Control,an HRP-Conjugated Antibody secondary antibody and related buffer.

Your experiment will include 4 simple steps:

a) Add your sample to the plate. The samples and Control sample are diluted by Dilution Buffer.

b) Add diluted Secondary antibody HRP-Conjugated Antibody 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 650 nm to remove background prior to statistical analysis. The OD Value reflects the amount of antibody bound.
