Protocol tips

Upstream tips	Protocol tips	Downstream tips
	To yield high RNA, give the column an extra wash with both RW1 and RPE buffers (3 total washes with each buffer).	"Include DNAse treatment for 15-20min. Ensure EtOH is completely evaporated off of the column prior to elution. Adjust time from 1min to 5 min at 60`C. Use water to elute the RNA that is warmed to ~60`C"

Publication protocol

Following additional organic extraction and ethanol precipitations, RNA pellets were washed with 70% ethanol and resuspended in distilled water. RNA from mid-log phase broth cultures and infected monolayers was isolated using the RNeasy Mini Kit (Qiagen, Valencia, CA, USA), according to the manufacture’s instructions with minor modifications.

Some help with RNA isolation using Trizol

Hello! I used Trizol to extract total RNA from in-vitro cultured bacteria (1 X 10^8 cells). After phase separation, I mixed ~0.4 ml of the upper phase which contains RNA with 0.5 mL cold isopropanol. However, the amount of RNA when measured in Nanodrop was very low. In addition, the ratio between 260 and 230 was around 0.1 to 0.5. Is there a chance that my sample was contaminated by the Trizol reagent? When I collected the aqueous phase I made sure to not touch the lower phase. What should I do?
