RNA isolation Cells - immortalized T98G

When extracting nucleic acids from cell cultures, thorough homogenization of cells via vortexing in lysis buffer is very necessary. Choose the best RNA isolation method keeping in mind the downstream applications, generally, column-based isolations result in clean and concentrated RNA samples. Downstream applications like sequencing and cDNA synthesis require high-quality RNA, always treat the samples with DNases and check their integrity by running a gel.

I am having trouble using the QiageN RNAeasy mini kit for CD34+ cells. Any tips?

Protocol tips
- For RNA to dissolve better and to yeild high levels, preheat elution buffer at 95C.

- Addition of β-mercapto ethanol in lysis buffer can be skipped because the phenol will do the job of nuclease inactivation.

- To capture more amount of mRNA, modify the amount of lysis buffer:ethanol (from 1:1 to 1:1.5) during the binding step.
Downstream tips
- Do vortex for 2-plus minutes during Acid-Phenol:Chloroform extraction step. This will facilitate the removal of tightly bound proteins typically associated with RNA.
RNAzol® RT

Molecular Research Center, Inc.

Upstream tips
- To reduce RNA degradation do not wash cells before the addition of RNAzol® RT.

- To reduce DNA contamination, use sufficient amount of RNAzol® RT based on the area of the culture dish and not on cell number.
Protocol tips
To reduce DNA contamination extend the incubation time to 15 minutes before sedimentation.
TRIzol Reagent

Thermo Fisher Scientific

Protocol tips
For low 260/230 readings the best approach is to try washing sample (precipitation) with ethanol to desalt it.
PicoPure™ RNA Isolation Kit

Thermo Fisher Scientific

Upstream tips
- Can be used when there is a very less amount of starting material.
