Our laboratory focuses on the mechanisms involved in the biological processes in relation to energy metabolism, stress responses and cell signaling pathway for sustainable and effective utilization of aquatic resources. The extraction of RNA from livers or muscles of various fishes is a part of laboratory’s daily work.
The quality of extracted RNA from torafugu pufferfish was good (Fig.1). For the torafugu pufferfish muscle which is exceptionally hard among the fish muscle, 5000 rpm 2x 30sec gave very good RNA yield (Table1). The 4000 rpm treatment was not enough (the homogenate looked somewhat granular). The RNA concentration extracted from the fish liver using Minilys was somewhat smaller than the amount of RNA extracted using Precellys®24.
