  • Evaluation of Different Pulverisation Methods for RNA

    Quality and integrity of RNA are critical for transcription studies in plant molecular biology. In squash fruit and other high water content crops, the grinding of tissue with mortar and pestle in liquid nitrogen fails to produce a homogeneous and fine powered sample desirable to ensure a good penetration of the extraction reagent. Objectivetissue pulverizer liquid nitrogen,RNA extraction from tissue at liquid nitrogen temperature is a common technique employed to protect against RNAse activity. A significant group of our customers use our tissue pulverizer for RNA extraction from tissues which are not very physically tough, such as brain or muscle tissue, as well as from tougher samples such as leaf or root tissue.
