What is the basic principle involved in the staining of fats and lipids with Oil Red O, Product O0625?
The Oil Red O is only minimally soluble in the solvent. Solubility is typically decreased by diluting the stock Oil Red O solutions in water before use. The Oil Red O then moves from the solution to the lipid - where there is greater solubility.
Is there a recommended staining procedure for Product O0625, Oil Red O, for staining fats or lipids in tissue sections.
Yes, there are several. Working solutions prepared without dextrin typically have shorter stability dating. The method of the Biological Stain Commission is listed in: Penny, DP et al, Analysis and testing of biological stains - The Biological Stain Commission Procedures. Biotech. Histochem. 77(5&6), 237-275, (2002). The Churukian method is also listed in Bancroft, J and Gamble, M; Theory and Practice of Histological Techniques, Churchill Livingstone, New York 2002 pages 207-208.
Can the Oil Red O, Product O0625, staining procedure be used with paraffin sections of tissue?
No. The solvents typically used in paraffin processing will dissolve away most of the fats and lipids. Frozen sections are the preferred tissue specimen.
Can Oil Red O, Product O0625, be utilized for staining adipocytes in cell culture?
Yes, although the cultured cells must first be fixed before staining. Preferred fixatives would include aqueous fixatives such as 10% neutral buffered formalin. Avoid fixatives such as ethanol or acetone. After fixation and rinsing, the cells may be stained with the basic procedures used for staining tissues attached to glass slides
Has product O0625, Oil Red O, been use-tested for staining lipoproteins in agarose gels?
Each lot of Product O0625 has been certified for use in histological applications by the Biological Stain Commission. It is not specifically use-tested for any electrophoresis application. We offer a different grade of Oil Red O (Product No. O9755) which has been tested for suitability in electrophoresis; each lot of O9755 has been tested and found suitable for staining lipoproteins that have been separated by cellulose acetate electrophoresis.
