Human Anti-SARS Antibody IgA Titer Serologic Assay Kit (Trimeric Spike)

Human Anti-SARS Antibody IgA Titer Serologic Assay Kit (Trimeric Spike)

Catalog Number:

F5L75

Background:

Severe Acute Respiratory Syndrome Coronavirus (SARS) caused the outbreak at 2002-2004 with over 8,000 people infection and 774 deaths. A rapid and effective assay kit detecting the levels of anti-SARS Spike in human serum can facilitate research on antibodies produced in response to SARS infection or vaccines.

Applications:

This kit is developed for serologic test for human IgA titer of Anti-SARS Spike antibody from serum/plasma or other tissues (e.g. mucosal samples) in vitro. It is for research use only.

Antibodies of IgM and IgA class are a sign of an active infection (primary infection and reactivation) and disappear during convalescence. In some cases they can persist for several months.

Description:

These kits were tested to bind to monoclonal antibodies in IgA format (Cat. No. Q74F36), see figures.

Biosafety Level:

BSL-1

Organism:

Severe Acute Respiratory Syndrome Coronavirus (SARS)

Assay Principles:

This kit is developed for a standard indirect-ELISA format, providing a rapid detection of anti-SARS Spike human IgA in serum. The kit consists of high-bind detachable 96-well plate pre-coated with trimeric spike protein, Positive control, Negative Control, an HRP-Anti-Human IgA secondary antibody, TMB and dilution/wash/stop buffer.

Use protocol (4 simple steps):

1. Detach wells from plate based on your samples and keep at room temperature. Dilute your samples, positive and negative controls in sample dilution buffer and add them to wells (0.1 ml/well). Incubate at 37°C for 1 hour or room temperature for 1.5 hour. Wash wells 4 times by wash solution (0.3 ml)
2. Dilute the Secondary antibody HRP-Anti-Human IgA by wash solution and add to each well (0.1 ml). Incubate at room temperature for 0.5-1 hour. Avoid light by foil. Wash wells as mentioned.
3. Add TMB to each well (0.1 ml) and incubate at room temperature for 5-30 minutes.
4. Stop the substrate reaction by adding stop solution (0.1 ml/well). Absorbance (OD) is calculated as the absorbance at 450 nm. The OD Value reflects the amount of antibody bound.

Storage and shipping condition:

Shipment with room temperature. The unopened kit is stable for 6 months from the date of manufacture when stored at 2°C to 8°C. Avoid light. The shelf life is 60 days from the date of opening.

Recommendations:

Customers who intend to use this kit to generate quantitative curves are suggested to consider the monoclonal antibodies to generate the reference curve: Recombinant Human Anti-SARS or SARS-CoV-2 S RBD IgA Antibody (Cat. No. Q74F36).
