Dear Histonet,
Dear Histonet,

DAKO redesigned the Seymour labels due to customer feedback.  Here are the
improvements that were implemented that enhance the performance of the
labels when exposed to xylene and heat.

* The Seymour Label adhesive was improved to withstand longer exposure to
xylene, especially after heat treatment. This is a dramatic improvement over
the previous formulation, and we have virtually eliminated adhesive
dissolving from the labels.

* The label stock was improved to provide a brighter label that is more
stain resistant to typical stains used in IHC, Special Stains and ISH.  This
will allow the labels to be easy to read, and look clean.

If you plan to soak the slides in xylene for extended amounts of time (In
excess of 30 minutes), lowering the level of xylene so that the label is not
directly exposed will improve the performance of the labels.

Sincerely,
Danielle Mach

I have been using the DAKO labeling system for 2 years. One thing you need
to be

aware of is that although the writing on the label is resistant to solvents,
the

glue on the back of the label is not. You have to keep your levels of
solutions
low enough not to come into contact with the label, especially any xylene
(This
includes longer exposure to xylene fumes also). The glue becomes goo and
will
seep out and down the slide. Otherwise, I agree with Tim Morken's accessment
of
the label maker.
