Hi Marc,
The Invitrogen TRIZOL reagent has worked very well for me in the past.  I
would try using a much larger number of embryos and follow the guidelines
for volume and mass (weigh a hundred embryos, for example, and use the
appropriate volume).  Also, are you using an electric tissue homogenizer? 
This really improves the yield as well.

getting very poor results.  I usually de-corionate then isolate the RNA
in batches of ~20 embryos (0-24 hrs) and batches of 10 for 48 (hrs).

also poor.

like to hear from them.
