The MasterTech Line features traditional hematoxylins that are optimized for performance. Gill hematoxylin is available in three strengths. With the highest dye concentration Gill 3 is ideally suited for routine H&E staining, producing a darker nucleus with shorter staining times than either Gill 1 or 2. This progressive stain produces distinct nuclear detail with great clarity. Use for automated or hand staining, as well as frozen sections.
