Biocare Medical Hematoxylin and Eosins

CAT Hematoxylin
Incredible nuclear detail in routine H-and-E and immunoperoxidase procedures, as well as for some special stains. This hematoxylin requires virtually no filtering and produces no scum due to oxidation. It has been specially formulated to eliminate the necessity for differentiation, and staining time is 30 seconds to 5 minutes, depending upon the type of procedure it is used for. The addition of acetic acid to CAT Hematoxylin's preparation is believed to increase the selectivity of the stain. The formula has also been designed to slow down the oxidation process, thus stabilizing the hematoxylin. There is no mercury used in the preparation of this product, glycerol has been added as a stabilizer to help prevent over-oxidation and rapid evaporation. (Modified Lillie-Mayer's).

Eosin Y
This modified alcoholic Eosin Y has been modified with the addition of stabilizers to have a prolonged shelf life. It is intended for use in the histologic demonstration of cytoplasm. Erythrocytes, collagen and the cytoplasm of muscle or epithelial cells should stain with three different intensities of pink.

Eosin-Phloxine
This is a specially formulated alcoholic Eosin Y/Phloxine B counterstain. This Eosin-Phloxine has been modified with the addition of stabilizers to prolong shelf life. Staining intensity is more subtle than other Eosin Y/Phloxine B formulations, however the pink shades are more vivid and alcoholic hyalin is also stained.

Tacha's Automated Hematoxylin
A highly stable bluing solution, which is designed for bluing hematoxylin stained nuclei. This solution can be used for both paraffin and frozen sections. It is nontoxic and odorless, available in ready-to-use or concentrate.
