Preclinical Biomarker Discovery

Preclinical Biomarker Discovery

Preclinical biomarker discovery strategies help to identify potential therapeutic targets, assess the safety and effectiveness of new compounds, and inform the design of clinical trials. If introduced early in preclinical studies, they can play a key role in reducing the cost and time required for drug development. 

Biomarkers can also help to identify subgroups of patients who are likely to respond to a particular therapy, which can inform the design of clinical trials and improve their chance of success.

Rely on our extensive experience and leverage our comprehensive resources for your preclinical studies. Our offerings include:

  • Preclinical Models and Databases: Access our wide range of in vivo and in vitro models, supported by comprehensive databases for baseline and historical data, essential for evaluating new therapeutic compounds.
  • Multiomics Biomarker Analysis: Explore biomarkers using our advanced genomics, proteomics, and metabolomics capabilities.
  • Experimental Design and Bioinformatics: Utilize our integrated tools for robust experimental design and efficient data analysis, ensuring precise and insightful research outcomes.


Biomarker discovery via in vitro screening


In vitro screening is time and cost-efficient, and can provide useful information on drug target(s) and targeted pathways. Utilize it to:

•    Explore/validate your drug mechanism of action (MoA)
•    Identify genetic features associated with drug response on a set of cell lines/organoids
•    Develop single or composite biomarkers
•    Provide advice and guidance on future in vivo model selection
