RNA isolation from gloms.

[Alexander Tzanidis]

The problem I am faced with is how to isolate total RNA from isolated rat 
glomeruli.
As a standard protocol, we routinely use the Cesium Chloride gradient 
technique to isolate total RNA from whole rat kidneys.  However, when 
applying the same technique to isolated glomeruli (isolated by seiving;  
approx. 1000 - 5000 gloms/rat), I am unsuccessful.
The glomeruli, once isolated, are resuspended in 1ml of 5M GTC (without 2-
ME) and stored at -80oC. 
Could the Chromczynski method (acidified phenol) be applied even though I 
have used 5M GTC rather than 4M GTC/SDS/2-ME?

Thank you
