The PEPperCHIP® Dengue Virus Type 2 Proteome Microarray covers the entire Dengue Type 2 viral proteome translated into highly overlapping peptides. The microarray chip contains 3,391 linear 15-mer peptides with a 14-mer overlap (shift 1) in duplicates for full epitope coverage. Moreover, the microarray contains HA, polio and c-Myc positive control peptides.
Identify, profile and compare Dengue Virus specific IgG, IgA, and IgM responses in patient or animal sera for vaccine development. Screen viral antigens to find and characterize immunodominant epitopes for in-vitro diagnostics research. The microarray can be used for proteome-wide epitope mapping, serum screening or biomarker discovery.
