Animals are euthanized by CO2 asphyxiation and fresh, unfixed tissue and organs are flash frozen in LN2 and stored at –80 degress Celsius. Special arrangements can be made for NIA-funded investigators for fixation of tissues or collection of additional ages or tissues such as bone. For information, contact Dr. Nadon.

The following tissues will be collected from each animal:

  • serum, 200 ul aliquots
  • brain, whole or hemisphere
  • cervical spinal cord
  • eyes, pair
  • sciatic nerves, pair
  • heart, whole, rinsed in Phosphate Buffered Saline
  • lungs, whole
  • liver, whole
  • spleen, whole
  • ovary or testes, pair
  • prostate (M), whole
  • muscle – thigh,
  • skin, shaved, from flank, approximately 1 x 1 cm square,
  • kidneys, pair, whole
  • adrenal gland, pair
  • white adipose tissue - subcutaneous
  • brown adipose tissue
  • thymus, whole
  • any tumors found
  • pancreas
