HepG2 cells were lysed and extracted by GTX16373 Plasma Membrane Protein Extraction kit.
When following the protocol, cell extracts would be isolated into cytosolic and total membrane.
The fractions were then assayed by Western Blot analysis, membrane was blotted with a plasma membrane protein- Na/K ATPase antibody (subcellular marker), a nucleolar small nuclear ribonucleoprotein- Fibrillarin antibody (GTX113684, subcellular marker) and beta Catenin antibody (GTX101435, internal control).

WCE : whole cell extract
