Monoclonal antibody-based drugs have the unique capacity to recognise a targeted cell through its expression of key biomarkers. Using direct and indirect means, these antibodies modulate the cell's intracellular signalling pathways. mAbs have a broad range of potential mechanisms to carry out their therapeutic activity and these activities can be measured in a number of ways including:

Apoptosis analysis
Proliferation/ death analysis
Cytokine release
Signal Transduction
Neutralisation

During the development of an in vitro biological assay to characterise the functional activity of a monoclonal antibody therapeutic several considerations should be taken into account:

Sensitivity of the assay to detect small changes in the biological function
Robustness of the method to day-to-day variability
Biological relevance of the approach
