International Classification:

G01N 130
G02B 2134

US Classification:

436174

Abstract:

The present invention includes adhesive solutions, devices and a method for the preparation of histological, cytological, immunological and proteinaceous samples for evaluation. The devices involve at least one sample deposition area formed from an adhesive composition, containing from about 0. 003% to about 1. 0% 1,5-dimethyl-1,5-diazaundecamethylene polymethobromide in a suitable solvent, wherein the adhesive composition is dried upon a solid support material such as a glass microscope slide or the like.
