Peptide Tools to Study SARS-CoV-2 and Its Variants
Applications of SARS-CoV-2 Peptide Tools
Our SARS-CoV-2 peptide pools offer a powerful resource for scientific and clinical research. These SARS-CoV-2 research products have been curated to support critical applications, such as:
- SARS-CoV-2 Clinical Trial Immune MonitoringOur peptides enable the monitoring of immune responses in clinical trials, helping researchers understand the impact of vaccines and therapies on SARS-CoV-2 immunity.
- SARS-CoV-2 Cross-Reactivity EvaluationEvaluate the cross-reactivity of SARS-CoV-2 peptides with other viruses, including common cold coronaviruses and other viral infections, to better understand immune responses and potential cross-protection.
- SARS-CoV-2 Blood and Serological Test DevelopmentLeverage our COVID-19 peptides for the development of reliable blood and serological tests. These peptides are essential in detecting antibodies and monitoring the immune response in infected and vaccinated individuals.
- SARS-CoV-2 T-Cell and B-Cell Epitope DiscoveryIdentify and map T-cell and B-cell epitopes using our comprehensive SARS-CoV-2 peptide pools, accelerating research into the immune system’s response to COVID-19 and its variants.
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 below!
