PEPperPRINT offers high-density peptide microarrays as well as linear and conformational epitope mapping services for antibody validation. Moreover, PEPperPRINT provides the Human Epitome Microarray with more than 23,000 human database epitopes for antibody cross-reactivity profiling and numerous other peptide microarrays for cancer, infectious disease and autoimmune research. Based on its proprietary laser-printing technology, PEPperPRINT can synthesize tens of thousands of peptides directly on the chip. The peptide microarray content can be easily customized– project by project. Recently, PEPperPRINT has broadened its product portfolio in biomarker discovery by introducing its neoepitope discovery platform for the identification of cancer biomarkers and the SeroRA® library for the development of IVD and CDx in rheumatoid arthritis.
