Source or provide human biological samples for scientific research with confidence, transparency and visibility.

Human biological samples (HBS) are used across the entire drug discovery research pipeline. They are an invaluable resource for target discovery, target validation, lead optimization, translational research and clinical development. Thousands of different types of human biosamples can now be sourced from hundreds of global service providers.

At we define human biological samples as biological materials acquired or derived from living or deceased human beings including but not limited to the following:

  • Solid specimens and certain processed human tissue e.g., tissue sections on slides
  • All primary tissue including primary cells (including bile, excreta and sputum)
  • Samples collected under informed consent during clinical trials/studies; and
  • DNA derived from human biological samples that is traceable to individual donors

  • “Research will accelerate when sample management and storage are outsourced to specialized, resource centers that can manage and monitor samples in a standardized way and [when] portals like transfer these samples to others who need them."

Reducing the Risks Associated with Sourcing Human Biosamples

Because they are of human origin, both research users and research providers must take great care to ensure that samples are handled with care and sourced ethically. Key questions include:

  • Has the donor provided consent?
  • Are the samples sourced from a qualified provider?
  • Are the samples traceable?
  • Are the samples single sourced, or sourced from multiple donors?
  • Are the samples properly characterized?
  • Are the samples accurate (genotype, age, race …)?
  • Do the samples meet internal and external (national) regulations?
  • Any of these missteps can lead to detrimental financial or reputational outcomes for organizations.

In 2015, launched an award-winning compliance platform called COMPLi® to answer these questions and reduce the risk inherent in sourcing human samples.  The COMPLi framework minimizes risk through a comprehensive and proprietary due diligence process conducted on all providers offering human biological samples, as well as on users requesting samples for scientific research.

COMPLi ensures visibility, traceability and transparency of sample usage without sacrificing quality or ethics. has human sample sourcing experts on staff to help guide supplier selection and to troubleshoot any problems that arise.
