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 vaccines and therapies that are safe, effective, and rapidly deployable is an urgent global health priority.

JPT's Peptide Tools to Study SARS-CoV2

The global research efforts as well as clinicial trials evaluating vaccines and drugs generates a demand for SARS-CoV-2 related peptide products enabling definition of immune-relevant antigens, identification of B- and T-cell epitopes, development of therapeutic & diagnostic strategies and clinical trial immune monitoring.
In response, JPT has launched a broad development program to provide access to genome spanning SARS-CoV-2 peptide tools for applications such as:

  • SARS-CoV-2 clinical trial immune monitoring
  • SARS-CoV-2 correlation of cellular and humoral immune responses
  • SARS-CoV-2 evaluation of cross reactivities
  • SARS-CoV-2 vaccine target identification
  • 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!
