How do you make bodipy?
Recipes
- 2 μM BODIPY staining solution. Prepare 5 mM BODIPY stock solution. Dissolve 1.3 mg BODIPY in 1 ml DMSO and can be stored at −20 °C. 2 μM BODIPY staining solution can be prepared by diluting stock solution 1:2,500 in PBS.
- 10× flow cytometry buffer. 0.1 M HEPES (pH 7.4) 1.4 M NaCl. 25 mM CaCl2 Notes:
How does bodipy stain lipids?
(2010) visualized lipid droplets within microalgal cells using BODIPY 505/515 and found that the fluorophore permeated all structures within a cell and the characteristic green fluorescence occurred when the dye is in both non-polar and polar environments, primarily staining neutral storage lipid droplets.
Is BODIPY hydrophobic?
BODIPY FL dye is a green fluorescent dye with unique hydrophobic properties ideal for staining lipids, membranes, and other lipophilic compounds.
How do Lysochromes work?
A lysochrome is a soluble dye used for histochemical staining of lipids, which include triglycerides, fatty acids, and lipoproteins. Lysochromes such as Sudan IV dissolve in the lipid and show up as colored regions.
What is the best method for quantifying lipid levels?
Nile red was previously used in semi-quantitative techniques [ 18, 23, 24] but, with improved methods, is now widely used to quantify lipid level. BODIPY 505/515 has been used more recently as a potential alternative to Nile red.
How to stain lipid droplets with BODIPY 505/515?
Staining lipid droplets with BODIPY 505/515 is mainly performed by flow cytometer, which avoids the fluorescence background of the medium and explains the limited information given about blanks in the literature. However, non-stained samples can be used as a control with cytometric analysis.
Is BODIPY-cholesterol assay better than filipin labelling?
Finally, the BODIPY-cholesterol assay proved to be the superior method to quantify cholesterol efflux relative to filipin labelling, though filipin remains useful for assessing cholesterol redistribution.
How do you measure lipid accumulation in adipocytes?
Because tools that automate single-cell analyses of heterogeneous populations of adipocytes remain at their infancy, lipid accumulation is most often quantified by measuring the amount of staining across an entire population of cells (Regnier et al. 2015; Boucher et al. 2016).
