The Cooperative Human Tissue Network (CHTN) is a unique, NCI supported resource. We provide human tissues and fluids from routine procedures to investigators who utilize human biospecimens in their research. The CHTN works prospectively with each investigator to tailor specimen acquisition and processing to meet their specific project requirements.

Biospecimens from surgeries, autopsies and other routine procedures:

  • Malignant
  • Benign
  • Diseased
  • Normal
  • Biofluids (urine, serum, plasma, buffy coat, whole blood)

High quality specimens at LOW processing fees:

  • Fresh
  • Frozen
  • Floating in fixative
  • RNAlater
  • Paraffin embedded or and/or unstained slides
  • Some divisions can provide RNA and DNA
