- The preparation of fresh tissue for histopathology involves the following steps12345:
- Immediate fixation: Freshly harvested tissue should be immediately fixed to avoid degradation.
- Fixation: Common fixatives include 10% Neutral Buffered Formalin (NBF) or 4% Paraformaldehyde solution (PFA).
- Processing: Tissues are embedded in paraffin wax and cut into thin sections.
- Staining: Hematoxylin and eosin (H&E) staining is commonly used.

www.ndbbio.com/post/tissue_fixationIn brief, histological processing involves obtaining fresh tissue, preserving it (i.e., fixing it) in order to allow it to remain in as life-like a state as possible, cutting it into very thin sections (3–8 microns), mounting it on glass microscopic slides, and then staining the sections so that they can be observed under a microscope to identify different histological components within the tissue.www.intechopen.com/chapters/64758The most common mode of routine tissue preparation involves fixation with buffered formaldehyde, embedding in paraffin, sectioning into slices about 5 micrometers in thickness, and staining with hematoxylin and eosin (H&E).histology.siu.edu/intro/tissprep.htmAs a general rule all fresh tissues are fixed in 10% neutral buffered formalin and are embedded in paraffin wax before cutting microscopic tissue sections. The embedding process requires dehydration of the tissues using organic solvents, permeation of the tissues with paraffin wax, and hardening of the wax for cutting.peir.path.uab.edu/wiki/Histologic:Chapter_1The Five Steps of Histology Slide Preparation
