  • Multi-Species Expertise processing and analyzing tissues from rodents to non-human primates.

Tissue Processing

The foundation of histological evaluation is the preparation of high-quality tissue specimens. Our core histology laboratory provides a complete service for both paraffin-embedded (FFPE) and frozen (OCT) tissues. We combine state-of-the-art automation with the precision of our highly experienced histotechnologists to ensure the consistent generation of tissue sections for any downstream application, from routine analysis to advanced molecular pathology.

Holistic Toxicology Study Support

To elucidate your therapeutic’s mechanism of action and confirm target engagement at the cellular level, we offer a suite of advanced molecular pathology services. BioLegacy provides development, optimization, and validation of custom staining assays to visualize and quantify key biomarkers directly in tissue. Used to assess drug efficacy and safety, our molecular pathology services provide critical insights into the biological response within the precise tissue microenvironment.

  • Immunohistochemistry (IHC)
  • Immunofluorescence (IF)
  • Custom antibody validation and protocol optimization
  • Multiplex staining for co-localization studies

Digital Pathology

BioLegacy’s histology workflow integrates state-of-the-art digital pathology. Leveraging powerful, unbiased image analysis we precisely quantify a wide range of pathological and biomarker endpoints. This rigorous, data-driven approach removes subjectivity, increases statistical power, and delivers the objective, reproducible results required for confident decision-making and IND submissions.

  • Whole slide scanning
  • Secure, cloud-based image management and viewing
  • Algorithmic image analysis
  • Quantitative analysis of cell populations, protein expression, and morphology
  • Board-certified pathologist oversight and interpretation

Secure & Compliant Archiving

BioLegacy provides secure, GLP-compliant archiving for all physical specimens, including wet tissues, blocks, and slides, in environmentally-monitored facilities to meet global regulatory requirements (including FDA § 58.195). Optional digital slide archiving provides you with instant, secure access to your virtual slides for future review, re-analysis, or remote collaboration, safeguarding your valuable data assets for the lifetime of your program without concern of sample degradation or loss of signal.

  • GLP-compliant archiving of all physical specimens
  • Secure, cloud-based archival storage
  • Remote access for viewing and collaboration
  • Long-term data integrity and disaster recovery
  • Facilitates future quantitative re-analysis
