Degradation of RNA present in a sample is detected by using, as an indicator, rRNA included in the RNA. The steps include: (a) introducing the sample onto a microchannel, at an introducing point, filled with an electrophoresis separation gel; (b) conducting electrophoresis of rRNA fragments present in...http://www.google.de/patents/US6251247?utm_source=gb-gplus-sharePatent US6251247 - Detection of degradation of RNA using microchannel electrophoresis
