Description |
Mice used in this study were 129/sv males, 8-15 weeks of age, which were housed individually and received water ad libitum. Total RNA and polyA RNA were prepared for each animal separately, and equal amounts of polyA RNA from each batch were pooled. Pool2 normal = 3 animals (No. N4, N5 and N6) fed during and before the 48h experiment with standard food, ad libitum; pool2 starved = 3 animals (No. St4, St5 and St6) fed before the experiment with standard food, ad libitum, starved during the 48h experiment. The microarray was scanned 3 times: low scan (suffix _L in data table) with a low amplification / intensity to avoid saturated spots for proper data analysis, high scan (suffix _H in data table) with a high amplification / intensity to detect also weak fluorescent spots which are missed in the low scan and medium scan which lies between high and low intensity and gives additional data points for subsequent calculations. For additional information see publication and web link. Keywords = nutrient response Keywords = starvation Keywords = liver Keywords = anti-aging Keywords = longevity Lot batch = mp7_031
