  1. 25 sty 2024 · When hematoxylin is completely dissolved, add sodium iodate, etc. Procedure: 1. Deparaffinize sections, 2 changes of xylene, 10 minutes each. 2. Re-hydrate in 2 changes of absolute alcohol, 5 minutes each. 3. 95% alcohol for 2 minutes and 70% alcohol for 2 miuntes. 4. Wash briefly in distilled water. 5. Stain in Mayer hematoxylin solution for 8 ...

  2. ve based on dye concentration. Progressive stains (e.g., Mayer’s hematoxylin) have a lower concentration of dye and selectively stain nuclear chromatin without s. aining cytoplasmic structures. The desired i. tensity is a function of time. If staining times are excessive, a progressive stain might act similarly.

  3. 21 sty 2024 · Mayers Hematoxylin Protocol. Dissolve alum in distilled water. When alum is completely dissolved, add hematoxylin. When hematoxylin is completely dissolved, add sodium iodate and acetic acid. Bring to boil and cool. Filter if it is necessary. Staining Characteristic. Progressive. Suggested Use.

  4. Mayer's hematoxylin is an alum hematoxylin, a commonly used stain that may be employed for both progressive and regressive stains. It is often used as a nuclear counterstain for special stains and immunohistochemistry. For these applications, Mayer's is used to stain the nuclei and then blued without the use of a differentiator.

  5. 25 sty 2024 · Lillie’s variant of Mayer’s haemalum is discussed in Lynch et al. (pp 1032) (please refer to Lillie Mayer) Haematin exhibits indicator-like properties, being blue and less soluble in aqueous alkaline conditions, and red and more soluble in alcoholic acidic conditions.

  6. Reagent preparation: The “Mayer‘s hemalum solution” used for stain-ing is ready-to-use; diluting of the solution is not necessary and would minimize the staining result and its shelf-life. It is recommended to filter the solution prior to use.

  7. concentration. Progressive stains (e.g., Mayer’s hematoxylin) have a lower concentration of dye and selectively stain nuclear chromatin. The desired intensity is a function of time. Regressive stains (e.g., Harris hematoxylin) color all nuclear and cytoplasmic structures intensely.
