ABSTRACT:
Disclosed herein is a process for separation and analysis of free and bound hydrophobic components in whole blood. In this process, whole blood is passed through an internal surface reverse phase material having particles large enough to allow blood cells to pass through. These particles have hydrophobic pores that are small enough to prevent penetration by proteinaceous substances and large enough to allow penetration by free hydrophobic components. Thus, free hydrophobic components are retained by the internal pore surfaces. A non-denaturing solvent is used to wash the whole blood through the material, and a hydrophobic or organic solvent may be separately used to wash the hydrophobic components from the material. This process may be combined with qualitative, quantitative, and selective detection techniques, such as radiolabelling. Effective therapeutic dosages of hydrophobic drugs may be determined by separating the free hydrophobic components by this process and then measuring the levels of the free and bound hydrophobic components to determine the proportion existing in free form.
