The GeneTex SARS-CoV-2 (COVID-19) Nucleocapsid Protein Sandwich ELISA Kit (GTX535824) is a ready-to-use in vitro assay for the quantitative measurement of SARS-CoV-2 nucleocapsid (N) protein. It allows highly specific, ultrasensitive detection of SARS-CoV-2 N protein with an average lowest detection limit of 18 pg/ml (Figure 1). The assay can be completed in less than four hours.

A key feature of this kit is a low background when testing plasma samples and a significantly decreased rate of false positives (Table 1). In addition, the optimized reaction formula generates a reliable recovery value for plasma samples, highlighting this kit’s outstanding performance when compared to similar products on the market (Table 2).

* The recovery rate is utilized to determine the differences in percent recovery between samples and standard diluent. The ideal recovery rate is 100%.
The SARS-CoV-2 (COVID-19) N protein is abundantly expressed during infection. It is one of four viral structural proteins, and binds the virus’s genomic RNA to form a helical ribonucleocapsid complex. N protein functions in viral genome protection, replication, virion assembly, and immune evasion. Through scrupulous design, production, and stringent testing, GeneTex has successfully developed a panel of recombinant monoclonal antibodies against SARS-CoV-2 (COVID-19) nucleocapsid protein and other antigens. The GeneTex SARS-CoV-2 (COVID-19) Nucleocapsid Protein Sandwich ELISA Kit (GTX535824) is composed of an antibody pair carefully selected to provide the highest signal-to-noise ratio for nucleocapsid detection in various sample types. This product represents another important addition to GeneTex’s growing catalog of SARS-CoV-2 reagents created to accelerate your COVID-19 research.
