The present invention proposes a new fixation method for transmission electron microscopy samples of brown adipose tissue to obtain better ultrastructures of mitochondria and lipid droplets. The fixation method of brown adipose tissue of rodents is optimized, mainly including increasing the concentration of paraformaldehyde in the pre-fixative from 2% to 4%; replacing the buffer of the post-fixative osmium tetroxide with an imidazole buffer; and adopting a fixation method combining cardiac perfusion and immersion. The structures of mitochondrial cristae and other membranous organelles of brown fat cells prepared by the new fixation method are more complete; lipid droplets appear as round structures with high electron density. The method was used to observe the increase in the density of mitochondrial cristae and the increase in lipid droplets in brown fat cells after cold adaptation.
