H&E protocol.docx 1997 HEMATOXYLIN & EOSIN (H & E) STAIN PROTOCOL PRINCIPLE: This protocol is applied in the routine staining of cationic and anionic tissue components in tissue sections. This is the standard reference stain used in the study of histochemical tissue pathology. SPECIMEN REQUIRED: Snap frozen human striated muscle.
Hematoxylin and Eosin Stain For Fresh Frozen Section (H&E) PROCEDURE: 1. Take slides immediately from freezer and place in cold fixative (10% Neutral Buffered Formalin or 4% PFA) for 10 minutes 2. Rinse slides in 1X PBS, 2 times for 3 minutes each to remove OCT or other tissue embedding compound 3. Rinse in a gentle stream of tap water for 1 ...
Protocol for H&E staining: While sections are in water, skim surface of hematoxalin with a Kimwipe to remove oxidized particles. Blot excess water from slide holder before going into hematoxalin. Coverslip slides using Permount (xylene based).
H&E Troubleshooting Table . Page 1 of 7 . Problem Cause Solution . 1. Nuclei not crisp, “smudgy” nuclei, nuclear bubbling or no distinct chromatin pattern seen. There is no variation in the nuclear chromatin patterns among cells, and there is no variation in chromatin staining within one nucleus. a) Fixation is incomplete.
H&E staining is a popular method in histology, used widely in medical diagnosis. The staining method involves application of hemalum, which is a complex formed from aluminium ions and oxidized haematoxylin. This colours nuclei of cells (and a few other objects, such as keratohyalin granules) blue.
To perform an H&E stain, follow the procedure below to re-hydrate, dehydrate and stain the tissue sections. Same solvents can be used for multiple tissue sections but should be changed daily or more often if they become contaminated (strongly colored by the stains). References: 1.
