[Histonet] Rnase free slides?

[Emily Sours]

Honestly, I think RNases are a bunch of hooha.  If you're being
careful anyway because you're doing a PCR, that should be enough.
Wear gloves, be sterile.
When I worked with a Russian post-doc, she said she did RNA in situ
hybridization without gloves and it worked.  Of course, god only knows
what her protocol was, as she had some crazy stories about Russian
labs.

And poems that take a thousand years to die
But ape the immortality of this
Red label on a little butterfly.
