Epididymal adipose tissue was collected from chow==Materials==* Mice* Dissection Tools* 2 mL Dounce Homogenizer* Hypotonic Lysis Buffe, cool on ice: {| class="wikitable"! style="font- (nweight: bold;" | Reagent! style=15) and high"text-fatalign: center; font-fed weight: bold;" | Amount (n=750 mL) C57BL/6 mice. Pooled fat pads were minced and dounce homogenized with 10 strokes in hypotonic lysis buffer (10mM ! style="text-align: center; font-weight: bold;" | Stock Concentration! style="text-align: center; font-weight: bold;" | Final Concentration|-| HEPES, pH 7.5, 10mM KCl, | style="text-align: center;" | 500 uL| style="text-align: center;" | 1M| style="text-align: center;" | 10 mM|-| Potassium chloride| style="text-align: center;" | 500 uL| style="text-align: center;" | 1M| style="text-align: center;" | 10 mM|-| Magnesium chloride| style="text-align: center;" | 75 uL| style="text-align: center;" | 1M| style="text-align: center;" | 1.5mM MgCl2 , 250mM sucrose, 5 mM|-| Sucrose| style="text-align: center;" | 4.28g| style="text-align: center;" | Solid| style="text-align: center;" | 250 mM|-| NP40| style="text-align: center;" | 2.5 mL| style="text-align: center;" | 10%| style="text-align: center;" | 0.5% NP40|} ==Protocol==* Dissect adipose tissue into weigh boat, and protease inhibitor cocktail). Lysates were filtered through determine the weight* Mince to small <1mm pieces with scissors* Transfer to a 100 µm cell strainer clean tube and spun add one volume of '''Hypotonic Lysis Buffer''' on ice* Homogenize with 10 strokes in a 2 mL homogenizer and transfer back to an eppendorf tube* Centrifuge at 1, 500g 4C for 5 min. Lipid and cytoplasmic fractions were removed and minutes at 1500g* Carefully remove the fat pad with tweezers, store if needed* Collect supernatant into fresh tube, carefully remove all remaining cytosol* Re-suspend nuclear pellet was resuspended in 1/10 of the original lysis buffer* Quantify protein content in both nuclei and cytosol by [[ Bradford Assay ]]* Take 20-50 uL and boil in SDS-PAGE lysis buffer, store remaining cytosol or nuclear lysate in -20 or -80
