[Histonet] Permanent Red

[Patti Loykasek]

Just a quick question on alternative chromogens. Has anyone had a problem
with Dako¹s Permanent Red coming out in recycled alcohols? This is a nice
alk. Phos. Chromogen, and I really like it. Occasionally though, it comes
out in the alcohols in our counterstaining/dehydrating set up ­ not every
time. We do use recycled alcohols in this set-up. If we switch the recycled
out for all fresh, we don¹t have this problem. Just wondering.
