What can I do to improve the yield and quality of the RNA?
The BioTechniques
Molecular Biology Forum brings bench scientists together in an
online community to ask for and share advice regarding laboratory problems.
This week’s highlighted question comes from the Microscopy and Imaging
Techniques forum.

I am trying to use laser capture microdissection to collect cells from paraformaldehyde-fixed midbrain sections from transgenic mice. What can I do to improve the yield and quality of the RNA? Source: NIH.gov
Q: I am trying to use laser capture microdissection to collect cells
from paraformaldehyde-fixed midbrain sections from transgenic mice. The
quantity and quality of RNA isolated were insufficient for real-time PCR. I
don’t need to stain the tissue because the cells of interest express GFP,
but because of this, I need to avoid alcohol dehydration. What can I do to
improve the yield and quality of the RNA?
A: For isolating RNA, you need to use a membrane slide if you are using
a 2 laser system. I would recommend that the samples…
A: Remember not to rely on oligo dT primers for the reverse
transcription step if you get enough RNA out of your tissue because
formaldehyde modifies the adenine in poly-A tails and therefore…
