[Histonet] Tissue scrolling

[Colleen Forster]

We cut alot if these. This is the protocol:

1. The microtome, blade and water bath are cleaned well. We follow
withRNAse Away wipe down as an added precaution.

2. We use a coplin jar of 100% ethanol for forceps, pick or whatever other
tool you might  use that comes into contact with and dip and clean in
between each sample. I actually have 2 sets and put them into the alcohol
and switch out each time.

3 I use the RNAse free tubes to put the curls into.

4. You must wear gloves.

5. If they don't pick the samples up right away they are placed in a -20
freezer for storage.

They have good results.

Respectfully,

Colleen Forster HT(ASCP)
