Some new methods for affixing sections to glass slides. I. Aqueous adhesives.


PMID 3590235

Abstract

As a new aqueous adhesive to affix sections to glass slides, hydrolyzed vinyltriethoxysilane--either pure, in combination with polyvinyl alcohol or with specially prepared aqueous polyacrylate solutions--was applied. The silane proved to be very effective in enhancing bonding to the glass surface. As a general aqueous adhesive, a solution of 2% polyvinyl alcohol (m.w. 108,000; 99.7% hydrolyzed) with 0.2% hydrolyzed vinyltriethoxysilane is recommended. This stock solution is diluted 1:10 to 1:50 and used directly to float sections onto slides on a warming plate.
