PolyQuant’s PQ-Cov-MS-2 peptide standard facilitates diagnosis of common respiratory infections in gargle solution or nasopharyngeal swabs with high accuracy and sensitivity through mass spectrometry.
The PQ-Cov-MS-2 peptide standard is based on PolyQuant’s proprietary QconCAT technology, providing 59 15-N labeled peptides (generated by trypsin digest).
Cov-MS-2 15N-labeled MS standard, peptide mix, digested, lyophilized
The peptide mix was generated by tryptic digestion of a 76.67 kDa synthetic protein comprising of peptides for the SARS-CoV-2 nuclear capsid protein (NCAP), Influenza A and B NCAP and matrix protein (MP) and the human respiratory syncytial virus A MP and phosphoprotein (PP). Additionally, the synthetic protein comprises of synthetic peptides for workflow calibration and standardisation (complementing product: RePLiCal, PQ-CS-1561).
