I wanted to amplify my message of 3/10. The tape-transfer method for
paraffin sections also uses an adhesive-coated slide which firmly bonds the
section--no loss with any protocol no matter how rigorous!

The section is supported and captured on a tape window as it is cut  and is
then transferred to the slide. The adhesive coating is polymerized in 30-60
sec. and the section is ready for deparaffinization and staining. The water
bath and drying steps are eliminated. Eliminating the water bath can be
important in some circumstances; antigenic activity of some epitopes can be
lost in the heated water bath!

This method has also become valuable for  new research using micro-arrays of
tissues. For  details see the "PSA" product on our web site
