Performance Validation Luminex Assays are validated for use with cell culture supernatants, plasma and serum. All Luminex assays are tested for sensitivity, intra-assay precision, inter-assay precision and to ensure assay linearity for validated sample types. Antibody pairs are selected and tested to confirm the parallel detection of natural and recombinant standard protein and to ensure the accurate determination of target analytes within biological samples. Assays for each target analyte are screened against all target analytes to confirm low antibody cross-reactivity.
