Eosin dye is acidophilic - Study guides, Class notes & Summaries

Absorption - correct answers When tissue is penetrated by, or absorbs, a dye solution and becomes colored without any other change or chemical reaction occurring. An example is the absorption of oil red O or Sudan black B by fat Achromatic - correct answers Without color, or not easily stained. In microscopy, achromatic lenses are corrected for two colors, red and blue. This helps produce images free of chromatic aberrations Acid mucosubstances - correct answers a term used to include bot...

Hematoxylin - CORRECT ANSWER dye is basophilic Eosin - CORRECT ANSWER dye is acidophilic Organelles stain Basophilic - CORRECT ANSWER Organelles that contain DNA and RNA such as nuclei, heterochromatin, nucleoli, ribosomes, RER Organelles stain Acidophilic - CORRECT ANSWER Cytoplasm, mitochondria, collagen, bone matrix, smooth ER Secretory Granules - CORRECT ANSWER Organelle can be either basophilic or acidophilic Protein Synthesis - CORRECT ANSWER Nucleolus is visibly dark and ar...

An example of an additive is one that contains: A. Picric acid B. Acetic acid C. Ethyl alcohol D. Acetone - correct answer Picric Acid When compared with tissue fixed in formalin, tissue fixed in zinc-formalin will show: A. Better ultrastructural preservation B. Decreased immunoreactivity C. Increased enzyme activity D. Superior nuclear detail - correct answer Superior nuclear detail Micr...

Heterochromatin correct answers form of DNA - tightly coiled, usually peripherally placed in the nucleus, dark-staining, inactive - not involved in RNA synthesis Euchromatin correct answers form of DNA - partially/fully uncoiled, centrally placed, light staining, active - involved in RNA synthesis Basophilic correct answers stains readily with basic dyes (e.g haemotoxylin is a basic dye that stains the nucleus - which is basophilic - blue/purple) Nuclear envelope correct answers double-...
