SRS210901 SAMN00621718 10116 Rattus norvegicus Rat pineal glands collected at mid-day (ZT7). SRS210902 SAMN00621719 10116 Rattus norvegicus Rat pineal glands collected at mid-night (ZT19). SRS210904 SAMN00621721 10116 Rattus norvegicus Rat non-pineal tissues collected at mid-day (ZT7). From 3 rats, 15 tissues were collected: cortex, cerebellum, midbrain, hypothalamus, hindbrain, spinal cord, retina, pituitary, heart, liver, lung, kidney, skeletal muscle, small intestine, adrenal gland. Total RNA was extracted from each tissue, and then equal amounts of each of the 15 tissues were combined for the final pooled sample.
