Assay develop­ment

The identification of the effects of new drug candidates requires extensive molecular investigations of cellular signal transduction pathways.

Miniaturized immunoassays can be used to detect differences in the activation of key proteins (pharmacodynamic and predictive biomarkers) in cell lines, tissue biopsies and tumors.

Reverse-phase protein arrays (RPA) and bead-based assay systems allow the comprehensive analysis of very small sample amounts.
