The increase in surface PS has led to the use of a number of proteins or peptides that bind to PS to study apoptotic and tumor cells [2, 4, 13]; among these are annexin A5 (ANXA5), an endogenous anticoagulant protein, and lactadherin (MFGE8) [2, 14], a major glycoprotein in milk that promotes cellular adhesion. The gene discussed is ANXA5; the disease is neoplasm.
