The PEPperCHIP® SARS-CoV Antigen Microarray covers four selected antigens of SARS-CoV-1 translated into 998 highly overlapping peptides. The microarray chip contains linear 15-mer peptides with a 13-mer overlap (shift 2) in duplicates for full epitope coverage. Each microarray chip contains three array copies for one-by-one assays. Moreover, the microarray contains HA, polio and c-Myc positive control peptides.
The microarray can be used for epitope mapping, serum screening or biomarker discovery.
