Histotechnology fixation - Study guides, Class notes & Summaries

Histotechnology- Fixation Fixation: - correct answers Alteration of biological tissue by chemical or physical means which stabilizes proteins found in tissue, preventing further metabolic activity. Purpose of Fixation: - correct answers To kill tissue and preserve it by limiting the effects of decay, putrefaction, and autolysis. Fixation also hardens tissue which makes it easier to gross, and easier to section once it is processed and embedded. Physical Agents: - correct answers - Heat an...

Carsons Histotechnology Question and answers already passed 2023/2024Mordant . substance’s or metals that act as a link between dye and tissue A mordant is a metal with a valency of at least two. The two commonest metals used in histotechnology are aluminum and ferric iron, both with valencies of three. The attachment of mordant to dyes is by means of a covalent and a coordinate bond. Fixative additive fixation- stabilizes proteins by denaturing proteins (chemical, heat) and combin...

BOC Histotechnology- Processing During microtome, it is noted that many of the tissues are very hard and shrunken. Of the following, the most likely explanation for this problem is that the: - correct answers INFILTRATING PARAFFIN IS TOO HOT. When tissue is processed in paraffin wax that is more than 2 degrees Celsius to 4 degrees Celsius above the melting point, the tissue becomes hard and shrunken. Decalcification of small specimens can be achieved by fixation in: - correct answers ZENK...
