Guinea Pig Anti-SARS-CoV-2 (Covid-19) IgG Antibody To Spike RBD Protein Quantitative ELISA
The Guinea Pig Anti-SARS-CoV-2 (Covid-19) IgG Antibody To Spike RBD Protein Quantitative ELISA is For Research Use Only.
Size: 1×96 wells
Standard Range: 0 ng/ml – 1000 ng/ml
Sample Type: Serum and Plasma
Reactivity: Spike Protein RBD
Detection Method: Colorimetric, Absorbance read at 450nm
The method employs indirect sandwich ELISA technique. SARS-CoV-2 Spike RBD protein is pre-coated onto microwells. Samples and standards are pipetted into microwells and Antibodies to SARS-CoV-2 Spike RBD protein present in the sample are bound by the protein antigen. After incubation the wells are washed and followed by addition of HRP-conjugated guinea pig Detection IgG Antibody into each well and incubated to form a complex. After washing microwells in order to remove any non-specific binding, the substrate solution (TMB) is added to microwells and color develops proportionally to the amount of Guinea Pig Anti-SARS-CoV-2 (2019-nCoV) in the sample. Color development is then stopped by addition of stop solution. Absorbance is measured at 450 nm.
Sample Preparation and Storage
- Specimens should be clear and non-hemolyzed. Samples should be run at a number of dilutions to ensure accurate quantitation.
- Blood is taken by venipuncture. Serum is separated after clotting by centrifugation. Repeated freezing and thawing should be avoided. If samples are to be used for several assays, initially aliquot samples and keep at – 20°C.
- Samples should be diluted 1:1000 (v/v) for optimal recovery, (for example 1 ul sample + 999 ul sample diluent) prior to assay. In cases where matrix interferences is under or over observed, the samples may be diluted with Sample Diluent accordingly.
- The samples may be kept at 2 – 8°C for up to three days. For long-term storage please store at -20°C.
Note: Grossly hemolyzed samples are not suitable for use in this assay
