Bolder BioPATH, Inc., an Inotiv company, is a contract pharmacology and pathology company specializing in in vivo models of Rheumatoid ArthritisOsteoarthritis, and Inflammatory Bowel Disease as well as other autoimmune and inflammation models. Our goals are to provide preclinical (efficacy and toxicity) data to support advancing proteins and small molecules to IND/NDA stage.




“At Bolder BioPATH, our mission has been to always deliver exceptional service and provide clients with the highest quality data to help them move quickly toward key decisions.”

- Alison Bendele, founder and President of Bolder BioPATH

Ex Vivo Analysis

We offer a wide array of ex vivo services, providing you with the data needed to efficiently make informed decisions.

  • Multiplexing offers an extensive list of analytes and can tailor any Luminex® profile to meet your needs
  • ELISA analysis
  • Fluorescent activated cell sorting (FACS)
  • Blood, plasma, serum analysis
    • Pharmacokinetic (PK) modeling
    • Stability

The DMT 620M Wire Myograph™ system is used to conduct ex vivo vascular ring tension recording on multiple vessel types including the aorta, the pulmonary artery and the middle cerebral artery.  The highly sensitive, flexible system can accommodate vessels down to 100 μm in diameter.  Relaxation and contractile activity are measured using force transducers. The system:

  • Allows ex vivo study of compound activity on vascular function
  • Enables assessment of antagonist potency for receptor/agonist combinations in both naïve and diseased model tissues
  • Assess vascular remodeling and function via pharmacologic challenge or evaluating length-tension relationships from therapeutic or prophylactic in vivo studies

Pathology Services

Our experienced staff engage in a broad spectrum of studies, tissues, species, and disease states.

  • Pathology assessment of tissues
  • Board certified veterinary pathologists
  • In vivo model sample analysis
  • Customized model development
