Human platelet CD36 (GPIIIb, GPIV) binds to cholesteryl-hemisuccinate and can be purified by a simple two-step method making use of this property.

CD36, also known as GPIIIb or GPIV, is a main protein of the platelet membrane. Accumulating evidence implicates CD36 in the pathogenesis of atherosclerosis. CD36 binds to cholesteryl-hemisuccinate coupled to agarose. This binding may be of physiologic relevance since CD36 has a long extracellular hydrophobic region at its N-terminus and belongs to a family of proteins involved in lipid metabolism. This newly discovered binding property of CD36 was used to develop a rapid, efficient and gentle two-step purification method for CD36 from human platelets.
