Abstract
In the field of staining methods for histology and cytology specimens, the improvements of the invention are three-fold. First included is a drying-clearing step whereby a specimen is cleared by drying. Thus, the use of hazardous chemical-clearing agents to remove washing-dehydrating solution prior to cover-slipping is eliminated. Second, in a staining method using spray staining equipment, the use of a low molarity, combination, bluing-washing solution which serves the dual purpose of a washing solution and a bluing reagent, eliminates the use of water in a staining procedure. Third, and also in a staining method using spray staining equipment, the use of a series of sprays of fresh, essentially anhydrous, washing-dehydrating solution to dehydrate a specimen replaces immersion in a series of washing-dehydrating solutions and thereby decreases the amount of chemical consumed and also avoids contamination of the reagent with water and specimen debris.
