Factors that distinguish heat inactivated plasma from plasma, serum, and recalcified plasma. Hierarchical clustering analysis was applied to 80 soluble factors measured in a total of 40 serum, plasma, and plasma derived components (as per Figure 1). The ten heat inactivated plasma components separated into a single group with one recalcified plasma component. A cluster of 15 soluble factors best distinguished the heat inactivated group from the other 29 components.
