Human Anti-Respiratory Syncytial Virus (RSV) Glycoprotein (G) Protein Antibody IgA Titer Serologic Assay Kit
Catalog Number:
D18J18
Background:
Respiratory syncytial virus (RSV) annually causes approximately 3 million acute lower respiratory infections in children and is typified by recurrent infections in infants. Two major surface structure glycoproteins of RSV, G and F protein, are responsible for viral attachment and fusion, respectively. A rapid and effective assay kit detecting the levels of anti-RSV G in human serum can facilitate research on antibodies produced in response to RSV infection or vaccine candidates.
Applications:
This kit is developed for serologic test for human IgA titer of Anti-RSV (A1 subtype) G antibody in serum/plasma or purified human antibody (monoclonal & polyclonal) 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 antibody in IgA format (Cat. No. U59T97) or human serum sample, see figures.
Biosafety Level:
BSL-1
Organism:
Human respiratory syncytial virus (RSV)
Assay Principles:
This kit is developed for a standard indirect-ELISA format, providing a rapid detection of anti-RSV glycoprotein (G) human IgA in serum. The kit consists of high-bind detachable 96-well plate pre-coated with G protein, Positive control, Negative Control, an HRP-Anti-Human IgA secondary antibody, TMB and dilution/wash/stop buffer.
Use protocol (4 simple steps):
- 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/well)
- Dilute the Secondary antibody HRP-Anti-Human IgA by wash solution and add to each well (0.1 ml/well). Incubate at room temperature for 0.5-1 hour. Avoid light by foil. Wash wells as mentioned.
- Add TMB to each well (0.1 ml/well) and incubate at room temperature for 10-30 minutes.
- 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 antibody to generate the reference curve: Recombinant Human Anti-RSV Glycoprotein (G) IgA Antibody clone RV84-IgA (Cat. No. U59T97).
