Assay Development

Customized Development and Validation of Assays

Creation and development of in vitro tests to measure the efficacy, safety and characterization of your biological products. These tests are particularly suitable for use in the screening of molecules and the release of clinical batches.

Our expertises

Karyotype, FISH.

Production of cell models which express molecules of interest. Transfection, cloning, selection, amplification.

Analysis in vitro of the cell responses: measurement of viability, proliferation, phenotype, specific functions (ex. ADCC, apoptosis, CDC), interferon activity.

Development and validation of quantitative PCR tests: detection / quantification of pathogens or contaminants, residual DNA, determination of sites of insertion of a transgene, gene copy number.

Development and validation of immunological assays.

Our solutions

  • qPCR & RT qPCR
