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.

Profile antibody responses against 33 Monkeypox Virus proteins.

The PEPperCHIP® Monkeypox Virus Peptide Microarray includes 33 proteins of the Monkeypox Virus (strain Zaire-96-I-16) converted into 5,207 highly overlapping peptides. The microarray chip contains linear 13-mer peptides with a 11-mer overlap (shift 2) in duplicates for full epitope coverage. Moreover, the microarray contains HA and polio positive control peptides.

The microarray can be used for epitope mapping, serum screening or biomarker discovery.
