I collected the medium from the culture wells. Do I need to now centifuge the medium and collect the supernatant or do I use the medium itself for the assay?
You can assay the cell culture medium directly. However, if it contains cellular debris you should first centrifuge it and then use the clear supernatant in the assay.
What is the principle of the assay?
In the process of adipolysis triglycerides are hydrolyzed by the cellular lipases into glycerol and free fatty acids. The assay measures glycerol, the end product of adipolysis, in a coupled three step enzyme reaction:
1) Glycerol kinase converts glycerol and ATP to glycerol phosphate and ADP.
2) Glycerol phosphate oxidase converts glycerol phosphate and O
2 to glycerone phosphate and H
2O
23) HRP converts ADHP and H
2O
2 to resorufin and water.
