Histology

VPS has a complete GLP-compliant histology laboratory that is capable of processing all types of animal tissues and medical devices.

Our Laboratory Director has over 25 years of experience in managing a GLP histology laboratory. Our laboratory staff includes 7 senior histologists, 14 histology technicians, and 3 research associates.

For routine paraffin histology, tissue cassettes and slides are auto-labeled by machine in order to provide consistent labeling without loss of information over time. Autostainers are used for H&E staining to provide consistent staining among all slides and tissues, and a variety of special stains are offered: e.g., Masson Trichrome, Safranin-O Fast Green, Toluidine Blue, Gram stain, etc. 

In addition to routine H&E histology, we specialize in providing nonstandard paraffin histology support for decalcified and/or oversized tissues, medical device studies, and projects that are considered too difficult for most paraffin laboratories.

VPS offers GLP-compliant plastics histology services, and is equipped with 2 GMA microtomes and 3 Exakt Systems.

GMA is often used to process delicate structures that are difficult to section in paraffin.

By infiltrating and embedding in Technovit 7200, our Exakt systems are able to section and grind tissues that contain: 

  • Metals (Titanium, Nitinol, etc.)
  • Ceramics
  • Undecalcified Bone
  • Bone Cements and Void Fillers
