100 Gyrodactylus salaris individuals comparison. Electropherograms (Experion) of totalRNA preparations from 100 Gyrodactylus salaris individuals using the AMB, EPI and ZR kits. 1% of each extraction was loaded on a Experion RNA HighSens Chip. The Z-scale illustrates the RQI/RIN values of the respective preparations. The AMB protocol yields high quality RNA whereas the EPI extract contains a substantial proportion of degraded RNA. The ZR extract is of high quality although the RQI/RIN values are low due to the unusual ratio of smallRNA and 18S/28S RNA.
