[Histonet] de-wax without organics

     I am curious what temperature and percent detergent you are using. Also
which detergent did you use? Some are different than others. Do you have a
list of special stains you have tried? I am sure this will probably work
great, I just think that it is conceivable for different labs using
different detergents, different concentrations and different temperatures to
get different results with some stains.
     This is a really cool subject and if you could compile the information
into an article I could find it a home in the Paraffin Press for the
Connecticut Society. Just in case you are interested.

We have run some preliminary tests on de-waxing slides using warm detergent
solutions rather than xylene or xylene substitutes.  So far the pathologists
see no difference between the H&E stained slides treated with detergent vs.
the usual xylene to alcohol to water route; the cellular detail is
equivalent and the dye reactions appear identical.   We have also run
comparisons for several special stains and IHC slides with good results.

I would greatly appreciate hearing from anyone who is aware of reasons why
this is a bad idea!  It is quicker and reduces the volume of organics
required by half so we are seriously considering it as an alternative

Thanks in advance for your feedback.
