RE: [Histonet] calling all muscle folks... PHOS coverslipping

From:"Smith, Allen"

In their original paper, Takeuchi and Kuriaki pointed out that one could
preserve the stain by adding iodine to the alcohols, xylene, and mounting
resin.  Haruo Machida, Edwin Perkins, and I took the trouble to find the
ideal iodine concentrations: 1 mg/ml of alcohol, xylene, or mounting resin.
We found that the best resin for this purpose was Clay-Adams' "Histoclad"=2E
Harleco's HSR was the only other satisfactory mounting resin. (Durable
mounts of the iodine stain for the phosphorylase reaction, Stain Technology
41: 346-347, 1966) I was able to take publishable photographs of
amylo-phosphorylase reactions preserved this way 25 years after the slides
were made.

Hi Julia,
after applying the iodine and air drying, we use 85%
Karo syrup to put a coverslip on the slide.  It stays
readable for about a weeek, but never gets solid and
of course, is not considered permanent.  We have a big
gooey mess of PHOS slides in a drawer that are
I may try some glycerine.
Thanks for responding,
