Pellets were washed two additional times (for a total of three washes) with 70% EtOH. RNA was resuspended in 50uL of 0.1% DEPC-H2O and spec'd on the Roberts Lab NanoDrop 1000. Results: ![](https://eagle.fish.washington.edu/Arabidopsis//RNA%20Spec%20Readings/20120124%20Gigas%20Larvae%20RNA%20ODs-01.JPG) Yields for the 4/12/2011 samples were all lower than the yields for the 7/5/2011 samples. However, the RNA quality (based on OD260/280 ratios) looks pretty good for both groups of RNA. RNA will be treated with DNase before reverse transcription.
