All tissues were collected at the age of 6 weeks. Kidneys and other organs were rapidly dissected and cleaned of fat, inserted into a vial, and immersed in liquid nitrogen for storage until RNA extraction.

The table below lists the arrays by strain and sample identifier. Each array was hybridized with mRNA from a single young male rat.
