Additive fixative - Study guides, Class notes & Summaries

Most coagulant fixatives achieve their full effect on tissue at any particular depth as soon as... - Answer they have penetrated to that depth at a concentration sufficient to cause coagulation. Fixative - Answer alters tissue by stabilizing the protein so that it is resistant to further changes. A fixative must change... - Answer the soluble contents of the cell into insoluble substances so that those substances are not lost during the subsequent processing steps. Denaturation - ...

An example of an additive fixative is one that contains: - picric acid Microscopic examination of an H&E stained section fixed in formalin shows marked nuclear bubbling. One most often sees this artifact if the specimen is processed following: - incomplete fixation Microscopic evalution of H&E stained sections from a surgically removed small bowl specimen shows an absence of much of the epithelium in otherwise normal tissue. This most likely resulted from: - delayed fixation When compared ...

Acetic Acid - correct answer Non coagulant, penetrates quickly and leaves tissues very soft. Used often as an additive to precipitate and preserve the nucleoproteins and fix the nuclei. Acetic Acid - correct answer Swells tissues dramatically by breaking collagen bonds and allowing bonds to absorb water. Used as additive to counter-act the shrinking effect of other fixatives. Formaldehyde - correct answer Non coagulant and additive fixative that reacts with amino groups that link pro...

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...

Endoplasmic Reticulum - Answer H&E basophilic staining within cytoplasm is due to what cellular structure? Pink - Answer Cytoplasm will show up what color on an H&E? 20 - Answer Proteins are made up of combinations of how many amino acids? Carboxyl group, side group - Answer All amino acids have an amino group and what other groups? Amphoteric - Answer Proteins can be _______, meaning they can be an acid or a base. Peptide bonds - Answer Amino acids are linked by...
