[Histonet] Once more b-galactosidase in lung

[t-kuzniar <@t> md.northwestern.edu]

Thanks for the advice, one more question. 

B-galactosidase is heat- and light-sensitive. How sensitive is it? I'm
cutting my frozen sections without any shielding and when they're drying
out for 10-30 minutes, they're unprotected from light either. I initially 
did not think it would matter, but maybe?

Thanks 

Tom
