Hi All,

I have a graduate student doing ISH on cell cultures. The cultures 
are grown on PLASTIC culture slides. He wants to counterstain with 
methyl green (has his heart set on it, actually!!), but because of the 
plastic, he cannot use acetone or xylene on his slides. Is there a 
solution that will allow him to continue with methyl green? Any 
suggestions for alternatives? Neutral red? Method? His substrate is 
blue. Thanks. Greg
