Peptide Tools to Study SARS-CoV-2

About SARS-CoV-2

SARS-CoV-2 (Severe acute respiratory syndrome coronavirus 2), the causative agent of Covid-19, is responsible for the current pandemic. Developing and monitoring vaccines, therapies and diagnostic tests that are safe, effective, and rapidly deployable is an urgent global health priority.

JPT's Peptide Tools to Study SARS-CoV2

JPT has launched a broad development program to provide access to genome spanning SARS-CoV-2 peptide tools and its different mutation variants for applications such as:

  • SARS-CoV-2 clinical trial immune monitoring
  • SARS-CoV-2 evaluation of cross reactivities
  • SARS-CoV-2 blood and sero test development
  • SARS-CoV-2 T-and B-cell epitope discovery

We have broadened our portfolio of coronavirus related products beyond SARS-CoV-2, including SARS-CoV, MERS-CoV and common cold viruses CoV 229E, OC43, HKU1 and NL63. Have a look!
