Useful for staining and quantitation of the accumulated oil in adipocyte

Lipid Assay Kit


Adipocyte accumulates neutral lipid in the cell maturing and neutral lipid is accumulated as lipid droplet. The evaluation of the amount of lipid droplet in the cell becomes criterion of the differentiation of the adipose cell.

Oil red O stain is one of the methods for determination of differentiation in adipocyte. Oil red O, the oilphilic red dye, stains intracellular lipid droplet. This lipid assay kit, consisting of cell fixative and oil red O solution, is used to stain the accumulated oil in adipocyte. Furthermore, this kit is able to quantify amount of oil with organic solvent extraction method.
This kit developed as option kit of White Adipocyte Culture Kit, Brown Adipocyte Culture Kit, Visceral Adipocyte Culture Kit. Put this kit to use oil stain and quantitation in adipocyte.

Kit component

One kit contains regents for 30 × 24well plates
Component Quantity Storage
Oil red O solution 150 mL×2 4°C
Solvent for Oil red O extraction 200 mL×2 4°C

< Protocol (24-well plate format) >

  1. Remove culture medium, and wash each well once with 500 μL of PBS.
  2. Add 500 μL of Fixative to each well, fix it over night at room temperature.
  3. After the fixation, wash each well three times with 500 μL of distilled water.
  4. Add 500 μL of Oil red O solution to each well, and leave at least for 15 min in room temperature.
  5. Remove Oil red O solution, wash each well three times with distilled water. Repeat until the distilled water is perfect clean.
  6. Dry it, and observe. In addition, add 500 μL of extraction reagent to each well, measure dye extraction (540 nm) by spectrophotometer or plate reader.

Viceral adipocytes (PMC-VAC01-COS) were stained by Lipid Assay Kit.
