Anti-SARS-CoV-2 Antibody IgG4 Titer Serologic Assay Kit

组分（Materials Provided）

产品概述（Product Overview）

It's been reported that coronavirus can infect the human respiratory epithelial cells through interaction with the human ACE2 receptor. The spike protein is a large type I transmembrane protein containing two subunits, S1 and S2. S1 mainly contains a receptor binding domain (RBD), which is responsible for recognizing the cell surface receptor. S2 contains basic elements needed for the membrane fusion.The S protein plays key parts in the induction of neutralizing-antibody and T-cell responses, as well as protective immunity.

应用说明（Application）

This kit is developed for serologic test for IgG4 titer of Anti-SARS-CoV-2 antibody in serum/plasma in vitro.

It is for research use only.

重构方法（Reconstitution）

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

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. The Kit consists of Pre-coated with SARS-CoV-2 Spike RBD Microplate, an Anti-SARS-CoV-2 Antibody (Control, IgG4), an HRP-Anti-Human IgG4 secondary antibody.

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-Mouse-Anti-Human IgG4 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 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 antibody bound.
