Human Anti-SARS-CoV-2 (BA.1) Antibody IgM Titer Serologic Assay Kit (Spike RBD)

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 anti-SARS-CoV-2 in human serum can facilitate research on characterization of antibodies produced in response to SARS-CoV-2 infection.

应用说明（Application）

The kit is developed for titer measurement of Anti-SARS-CoV-2 (BA.1) IgM 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 IgM in serum by SARS-CoV-2 Spike RBD. The kit consists of Pre-coated SARS-CoV-2 Spike RBD (BA.1) Microplate, an Positive Control, an Negative Control,an HRP-Anti-Human IgM secondary antibody and related buffer.

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 a diluted Secondary antibody HRP-Anti-Human IgM 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.
