That may be what you have to do, as the first day of ISH needs to be RNase free!
When I do them, it is 10 slides at a time and we have dishes and a lab bench
set aside for RNase free procedures only. Obviously this is not feasible in
all workplaces!
I would just think about it logically. Use gloves when you can, always.
Can you keep the hybridizing part RNase free? I don't know what machines you
use for this--we do process the slides manually in glass dishes and then
hybridize in a slide container and oven kept for RNase free purposes.
After hybridization, you don't really need to be too careful.
Now I'm wondering if there's some sort of magical machine that does ISH!
