I need some help with a method for plant total RNA extraction.
We have been using a classic method using phenol and LiCl
in a Tris/SDS grinding buffer, followed by chloroform
extractions, 2M LiCl precipitation, and EtOH pptn.
This gives fair to poor results with lots of sample-to-sample
and day to day variability.
I just tried out a guanidium thiocyanate method with very poor
resuslts- basically my first isopropanol pellet (after 1st
chloroform extraction) contained a huge amount of junk which
refused to redissolve.
I need a plant method that is fairly quick and amenable to
scale up for handling lots of samples per day.
