In average, total cellular proteins account for less than 2% of adipose tissues. Fractionation of adipose tissue

is technically very challenging due to its high lipid and low protein contents. Adipose tissue especially white

adipose tissue (WAT) has been recognized as an important endocrine and inflammation organ in addition to

its energy storage function. Fractionation and analysis of proteins from adipose tissues are critical for

understanding many physiological/pathological conditions. Thewater-oil emulsion present in biological

sample is notoriously difficult to separate. We have developed a novel technology to deal with this issue. A

porous filter with unique surface property and pre-defined pore size coupling with a specially formulated

detergent-free fractionation buffer is the key to fractionate adipose tissue into two fractions: water-soluble

protein fraction containing mainly cytosolic proteins and water insoluble fraction containing mainly plasma

membrane, and organelles such as mitochondria.The buffers used in this kit are free of primary amine,

detergent and reducing agents. Isolated proteins are compatible with all downstream applications including

TMT labeling, enzyme digestion, MS analysis and other applications.

A. SDS-PAGE (10%) profiles of fractionated adipose tissues. Lane 1, water soluble fraction of porcine WAT;

Lane 2, water-insoluble fraction porcine WAT; Lane 3, water soluble fraction of rat WAT; Lane 4, water-

insoluble fraction of rat WAT.

B. Western blottings of fractionated proteins from rat WAT; Lane 3. water solublr fraction; Lane 4 water in-

soluble fraction. Proteins were separated in 10% SDS-PAGE and probed with following cellular protein marker

antibodies: Anti-Na/K ATPase alpha1, a plasma membrane marker(Upstate, clone 464.6), anti-lamin B1, a

nuclear envelope marker (ab16048, abcam Cambridge, MA), anti-ubiquinol-cytochrome C reductase core

protein (abcam, ab 96333) and GAPDH, a cytosolic marker (Sigma). The specific protein bands were

visualized by a substrate Opti-4CN (Bio-RAD).
