Sudan III (CAS 85-86-9)

用法 :

• A saturated solution in isopropanol is prepared for use as a fat stain in animal tissue. Counterstain for 5 minutes in acid alum hematoxylin (approx. 0.1%). Fats will appear yellow orange in color and the nuclei will appear blue. The cytoplasm will appear green.

• Since lysochromes are soluble in non polar solvents, including xylene and toluene, and also in ethanol, these fluids must not be put on to sections after fats have been stained or the dye will be dissolved out; therefore resinous mounting media are not recommended. We recommend mounting sections with Crystal Mounting Medium; sc-24943.
