In light of the ongoing coronavirus disease (COVID-19) pandemic, PEPperPRINT has rapidly developed and produced a new peptide microarray based on the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral genome. Derived from the virus isolate sequence under GenBank ID: MN908947.3 (including 49 mutations of the B.1.1.7, 501.V2, B.1.1.28 and P.1 Manaus variants), the PEPperCHIP^® SARS-CoV-2 Proteome Microarray gives researchers access to serologically screen 4,932 individual peptides spanning the entire viral proteome.

PEPperPRINT's proprietary peptide laser printing technology, the high-density PEPperCHIP^® Peptide Microarrays provides a platform for:

• Antigen and Epitope Discovery
• Epitope Mapping
• Epitope Substitution Scans
• Immune Monitoring
• Serum Biomarker Discovery
• Peptide Target Binder Development

Identify and compare virus-specific antibody epitope recognition of different human coronavirus spike protein antigens in a single assay with the new PEPperCHIP^® Pan-Corona Spike Protein Microarray. The chip contains the spike proteins of all seven human coronaviruses (SARS-CoV-2, SARS-CoV, MERS-CoV, HCoV-HKU1, HCoV-OC43, HCoV-NL63, and HCoV-229E) translated into 4,564 individual peptides for a multiplexed epitope mapping.
