Microtechniques : Fixation, Dehydration, Block Peparation, Microtomy and Staining of Rat Tissue

September 12, 2024September 12, 2024 Rajkumar Pawar

Microtechniques: Microtechniques are specialized methods used to prepare biological samples for microscopic examination. These techniques involve a series of steps that preserve the structure of the sample, allow for thin sectioning, and stain specific components for better visualization under a microscope. Rat is dissected and Ovary/Testis, Intestine or kidney is taken out and fixed in…
