thanks...
Sorry, I forget the topic is about library preparation
Guys in our wet lab said it is hard to say the mass of total RNAs, may be 1mg? They just followed the protocols. Sometimes only when the sequencing finished then you know if the exaction is messed up or not. In the beginning, some sequencing batches of our samples were full of adaptor sequences only, useless .
