I have a problem in poly(A)-Northern:
A possible signal is much longer (4.5-4.7 kb) than my mouse cDNA (1.8 
kb). How do I discriminate the real signal and 28S rRNA which might be 
present in poly(A)RNA and even recognized by my probe? With rRNA specific 
Does anybody know where I can find a probe for mouse 28S rRNA?

best regards,
