I have tried homogenization, followed by centrifugation at high speeds for 40 minutes, followed by centrifugation through a concentrator filter. I suspect my BCA assay was not accurate as I had issues with lipid contamination in my sample that led to down stream problems with my western blot (namely that the loading was not equal with our GAPDH). Thanks!
my colleague at the University of Virginia, Susanna Keller works with adipose tissue. Check out her papers on how she processed tissue. good luck

Tyk2 and Stat3 regulate brown adipose tissue differentiation and obesity.
Thanks, Brandon! I will read up on them now and contact her directly if I am not clear on her methods.
no problem at all. Below is a link to her profile at UVA. I am not sure that she is on researchgate. Good luck!

There are techniques that have been published using trizol isolated proteins for western blot. I have listed 2 below. Good luck!
