Presented by: Jill Roughan, PhD, Technical Sales Representative of PEPperPRINT GmbH, San Diego, USA
Date: September 7, 2016

Antibodies are essential life science tools for therapeutics, basic research and diagnostic tests. However, mono- and polyclonal antibodies are often poorly characterized in terms of specificity and cross-reactivity, as summarized in the recent Nature Feature Reproducibility crisis: Blame it on the antibodies. The Human Protein Atlas consortium from Sweden showed that less than 50% of commercially available antibodies can be effectively used for immunohistochemical tests, which underlines the urgent need for antibody validation and cross-reactivity testing.

Based on its laser printed high-density peptide microarrays, PEPperPRINT developed a comprehensive toolbox for antibody validation and cross-reactivity analysis. This toolbox comprises solutions for linear and conformational epitope mappings, epitope substitution scans for the identification of conserved and variable amino acid positions for antibody binding, and robust cross-reactivity screening with the new PEPperCHIP® Human Epitome Microarray. To learn more about PEPperPRINT’s toolbox for accurate, fast and cost effective antibody characterization and validation, we invite you to watch our scientific webinar.
