Description

Differentiating Solution is intended to be used as an aid in hematoxylin staining for the diagnosis of general pathology specimens. Differentiating Solution is an acid alcohol solution to be used with the Modified Harris Hematoxylin. It is formulated as a standard 1% hydrochloric acid in 70% alcohol solution and will provide consistent differentiation results. Differentiating Solution’s mode of action is that it aggressively reacts with the tissue dye-lake complex in nuclear chromatin, resulting in the removal of the stain. Due to weak bonding in the cytoplasm, hematoxylin in this area is also easily and completely removed. Generally, two to four quick dips will be adequate for differentiation when using Differentiating Solution, followed by a 1-minute water rinse to stop the reaction and fully remove the acid from the tissue.
