 Hi everyone.

    I need to find protocols for Northern and ribosomal RNA electrophoresis 
courrently working with yeast and I have tecnicals troubles.

   I have run electrophoresis 5, 10, 15 ug of rRNA  was extracted with:
a) acidified phenol, heating to 65§ C.
b) phenol-clorophormo- isoamilic and glass beads(bortex).
   and cuantified by OD at 260 nm.

   I heve also stain the agarose gels with etidium bromide and I have not 
seen the bands 25S and 18S rRNA.
   All my glassware has been trated with DEPC.

   I shall be gratefull for any help.
