Hi histonetters,

I amwondering if anyone would tell me the limitations of methyl green pyronin for plasmacytoma. 
Though I am looking foolish, I think RNAs would increase in the cytoplasms of most actively proliferating  tumor cells, so I am curious is it possible to use this stain to differentiate plasmacytoma cells from other tumor cells based on the pyroninophilia of the cytoplasm. I remember reading somewhere this stain is non specific, but I could not find it....please help me, clarify me....on this subject

Thanks in advance,
