PQ-Cov-MS peptide standard is based on PolyQuant’s proprietary QconCAT technology providing 17 validated peptides as heavy isotope labelled or as unlabelled artificial protein where the peptides will be released by protease treatment with trypsin during sample preparation.
The synthetic protein comprises of 2 reference peptides for the SARS-CoV-2 Spike protein, 15 reference peptides for the (highly expressed) nuclear capsid protein (NCAP), control peptides for histone H2A, H2B, H3 and H4 to determine sample quality and synthetic peptides for workflow calibration and standardisation by our complementary product RePLiCAL.

Whitepaper and application notes
Mass spectrometry-based Detection of SARS-CoV-2 Infection
In this whitepaper we describe the development of Cov-MS for detection of SARS-CoV-2 infection in nasopharyngeal swabs and its suitability in clinical assays.
Our prices are net prices, i.e. they do not contain value added taxes or customs fees. These taxes have to be paid by the customer.
Our products are usually shipped 1-2 business days after receiving the order.
Delivery costs depend on destination and packaging (either on dry ice or ambient temperature shipping).
