ANXA5 and neoplasm: As shown in Figure 6, when data from all tumor samples were combined (EL4 and S180 tumors were not distinguished from each other), it could be observed that the number of apoptotic cells (abscissa) was linearly correlated with the percentage of 99mTc-HYNIC- annexin V taken up by all tumors (ordinate), with a correlation coefficient (r) of 0.892 and a corresponding P value of < 0.001.
