concentration of triglyceride (TG) was determined using the method
of Senarath et al.(45 (link)) with
a few modifications. Briefly, mature adipocytes obtained on the eighth
day were rinsed twice with PBS; the cells were scraped into PIPES
(Piperazine-N,N′-bis(2-ethanesulfonic acid)) buffer with 0.1% Triton X and
lysed by sonication on ice. The TG level in the lysate was measured
using the triglyceride E-test Wako kit (FUJIFILM Wako Pure Chemical
Corporation) according to the manufacture’s protocol.
