Although they are a little expensive, I would recommend you buying
some superfrost plus slides.  You can get them from Fisher (cat number
12-550-15), or from Erie Scientific.  In my experience, they bind
tissue much better than treatments like poly-l-lysine, and can save
you a lot of heartache over lost sections.

No affiliation with fisher etc
