詳細

Oil Red O は脂質を赤橙色に染色します。空胞も染色し、特に ALL-L3(急性リンパ性白血病)またはバーキットリンパ腫/白血病において染色が観察されます。アルコール固定により脂質が除去されるため、Oil Red O 染色は新鮮サンプルに使用されます。[1][2]

アプリケーション

Oil red O は lysochrome(脂溶性色素)ジアゾ色素であり、凍結切片上の中性トリグリセリドおよび脂質ならびにパラフィン切片上のいくつかのリポタンパク質の染色に使用されます。組織学においては、Oil Red O の過飽和イソプロパノール溶液が組織中の脂質の染色に使用される場合があります。
Oil red O 溶液は中性脂質および脂肪細胞の染色、ならびに線維芽細胞中の脂肪滴の可視化に使用されます。[3][4][5]

質問

1–6/6 質問  
  1. Hi! I'm wondering if OilRedO is light sensitive? Does the incubation need to take place in the dark? And could the staining of cells be compromized if the solution is not kept dark?

    1 回答
    1. There are no definitive references or citations confirming the light sensitivity of this material. However, this product is packaged in amber glass may be susceptible to light, particularly at UV wavelengths. In bright field microscopy slides must be viewed in subdued light. While this item is not tested for use in fluorescent, it has been used on Flow Cytometry and has an emission wavelength of approximately 600 nm. There are a number of publication indicating light sensitivity. See the link below to review on such example:

  2. What are the differences between Oil Red O solution O1391 and OIL RED O staining solution 1.02419?

    1 回答
    1. There are not many differences between products O1391 and 102419. O1391 is available in 250 mL and 500 mL bottles, while 102419 is available only in a 250 ml bottle. The only practical difference between the two products is the solvents used to dissolve the Oil Red O. For O1391, the solvent used is isopropyl alcohol, while the solvents used for 102419 are acetone and ethyl alcohol. Both products use Oil Red O as the dye, and the directions for use call for diluting the product with water prior to use and then filtering. The results should be identical since both products use Oil Red O as the dye.

  3. Should cells or tissues be fixed before staining with Oil Red O for fats or lipids?

    1 回答
    1. Yes, cells or tissues need to be fixed before staining with Oil Red O. It is important to avoid using fixatives that contain alcohol. Oil Red O staining can be performed on cultured cells and fresh frozen tissue. However, tissues should not be paraffin embedded and exposed to the alcohols and solvents necessary for paraffin processing tissue.

  4. Hi I purchased Oil Red O solution – 0.5% in isopropanol, 01391 250mL, PCode-1003585017, Source, SLCP2956 for staining of whole mice aorta. I want to dilute it to 0.16% solution. What solution should I use for dilution? MilliQ water/methanol/isopropanol?

    1 回答
    1. This product can be further diluted using distilled water or aqueous buffer to reach the desired concentration. Note that solution diluted with water or aqueous buffers are less stable and should not be stored for extended periods.

  5. Can I use this solution for stain frozen sections ? I thought that I bought oil red in propylene glycol. What is the difference ?

    1 回答
    1. This O1391 is a 0.5% solution in isopropanol. Product O1516 is a 0.5% solution in propylene glycol. The protocol for either product is the same. There is some evidence in the literature that the propylene glycol solution performs better on PFPP samples, however this is not definitive and may depend on conditions and technique. Each is considered a stock concentration. Stock solutions can range from 0.2 - 0.5%. Depending on the specific application the stock solution will need to be further diluted by 40 - 60%. For example, in staining frozen sections, 30ml of the O1391 would be diluted with 20ml of distilled water to reach a working concentration. Note that solution diluted with water or aqueous buffers are less stable and should not be stored for extended periods.

  6. How do you prepare the working solution using this reagent? or is it already a prepared working solution?
