Here, we present conditions for optimizing the measurement of lipolysis in murine adipocytes. We demonstrate that adenosine management is of paramount importance in evaluating the lipolytic response under basal and stimulated conditions. Also, adipocyte concentrations in the 10,00015,000 cells per milliliter range produce a greater increase in stimulated lipolysis than higher concentrations, and the response is further enhanced by agitating the cells.
