Standardising Northerns

[Dr. S. Bhattacharya]

Hi all,

I read somewhere that a 18S rRNA probe is a better option than the usual
actin for correcting loading variations on northern blots.  Does anyone have 
any ideas on this,
and has anyone done it using a oligonucleotide probe to 18s RNA (if so could 
they let me know the oligo sequence), as I do not have a cDNA probe.  

Many thanks
