Luminex Assay Services

Seamlessly go from PEPperCHIP® Peptide Microarray-based large-scale epitope discovery or from HuProtTM Human Proteome Microarray screenings, to target validation with a Bead-Based Multiplex Assay Validation workflow.
 

 

Fig. 1. Proposed workflow for epitope discovery and validation. Serum samples are initially screened with PEPperCHIP® Peptide Microarrays displaying peptide libraries of up to 70,000 peptides. Identified hit candidates are further validated applying a multiplexed bead-based immunoassay (Luminex MAGPIX® System).

 

The multiplexed bead-based immunoassay can be applied with serum or plasma samples, as well as hybridoma supernatants, and also include full length proteins. This enables the correlation of antibody responses against one or more epitopes with antibody responses against the full length antigen.
