Newcomer Supply Hematoxylin Stain, Gill III, 500 ml

Use: Frozen sections & IHC darker staining & high volume. Newcomer Supply Hematoxylin Stain, Gill, is a ready to use progressive nuclear stain available in three strengths for cytology and histology applications. Due to the progressive staining nature of Gill hematoxylin, over-staining is less likely and a differentiation step is not required. Gill hematoxylin does not require filtering but if using any Gill hematoxylin for cytology specimen staining, filtering before each use is highly suggested to prevent solution contamination. Gill III is “triple strength”, used primarily for tissue sections when a darker nuclear stain is preferred with shorter staining time. Goblet cells will stain with Gill III and moderately by Gill II but not by other hematoxylin solutions. Shelf Life is 1 year from date of manufacture. Store at 15-30°C.
