Waters SARS-CoV-2 LC-MS Kit
Waters has launched the research-use-only SARS-CoV-2 LC-MS Kit, which uses an orthogonal analytical method to directly detect and quantify SARs-CoV-2 Nucleocapsid peptides. According to the company, testing has shown that researchers can achieve the analytical sensitivity required to detect and quantify low levels of three unique peptides derived from the SARS-CoV-2 NCAP protein, with data on the Xevo TQ-XS System showing a lower limit of quantitation of 3 amol/µL. Waters said this is made possible by using an anti-peptide antibody enrichment sample prep method and antibodies from SISCAPA Assay Technologies. Results can be captured with clean, low-noise chromatograms in less than two minutes per sample, Waters added. The kit has been optimized on both the Xevo system and the Acquity I-Class Plus System, the company said.
