Nile red is an uncharged hydrophobic molecule whose fluorescence is strongly influenced by the polarity of its environment. It interacts with many, but not all, native proteins, including beta-lactoglobulin, kappa-casein, and albumin, with a wide range of spectral changes for

The Golgi apparatus plays a central role in the intracellular transport of macromolecules. However, molecular mechanisms of Golgi-mediated lipid transport remain poorly understood. Here, we show that genetic inactivation of the Golgi-resident protein GRASP55 in mice reduces whole-body fat mass

Questions

  1. How should n3013 be dissolved and diluted for lipid staining?

    1 answer

    1. There has not been any conduct suitability testing for Nile Red. Please see the following for an article that may offer information; J. Histochem. Cytochem. 35:619-621 reference.
      To perform the staining, a stock solution of Nile red was prepared by dissolving 10 mg of Nile red in 10 ml of acetone, which was then stored in the refrigerator protected from light. The sections were fixed in 1% glutaraldehyde in PBS for 5 minutes and washed in PBS three times for 2 minutes each. The staining solution was then prepared by diluting 100 ul of the stock solution in 1 ml of PBS. The sections were covered with this solution for 20 minutes at room temperature, then briefly washed in PBS and mounted in 75% glycerol in PBS. Other sections were incubated with solutions containing 50, 10, and 1 ug and 100 ng of Nile red per ml. The sections were examined with a filter set for fluorescein fluorescence (450-500 nm band pass excitation filter, a 510 nm center wavelength chromatic beam splitter, and a 528 nm long-pass barrier filter) and were photographed.
