Preparation of tissue for study

Preparation of tissues for study Is the branch of science which deals with microscopic study of tissue affected by disease. Tissue can be obtained from Tissue Preparation: Examining tissue samples through the microscope is not as simple as cutting slices and looking through the lens. There are several steps that must be taken after sample acquisition before a sample is ready for the scope. The four major steps include fixation, dehydration, embedding, and staining. Fixation Preparation of Tissues for Study, The most common procedure used in the study of tissues is the preparation of histological sections or tissue slices that can be studied with the aid of the light microscope.

Tissue preparation is the cornerstone of immunohistochemistry. To ensure the preservation of tissue architecture and cell morphology, prompt and adequate fixation is essential. However, inappropriate or prolonged fixation may significantly diminish the antibody binding capability The preparation process kills the tissue and can also cause changes in the sample's appearance. For scientists who wish to view biological samples, this poses a challenge - how can the sample be preserved so that it looks as much as possible like it would in the living organism, while still being able to withstand being visualised in the.
