	"For RNA to dissolve better and to yield high levels, preheat elution buffer at 95C. Addition of β-mercaptoethanol in lysis buffer can be skipped because the phenol will do the job of nuclease inactivation. To capture a higher amount of mRNA, modify the amount of lysis buffer :ethanol (from 1:1 to 1:1.5) during the binding step. Do vortex for 2-plus minutes. This will facilitate the removal of tightly bound proteins typically associated with RNA."

Publication protocol

Samples were grown in CA-MH broth to an OD600 of 0.6 before addition of RNAprotect bacteria reagent and RNA extraction using the mirVana RNA isolation kit (Ambion). A total of 500 ng of RNA was converted to cDNA using Superscript II (Life Technologies) followed by qRT-PCR using SsoFast Sybr green (Bio-Rad).

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?
