Abstract

See full text

This disclosure is directed to systems for separating a target analyte from a suspension. A suspension is added to a tube. A float is also added to the tube, and the tube, float, and suspension are centrifuged together, causing the constituent components of the suspension to separate into different layers along the axial length of the tube according to their specific gravities. The float has a specific gravity that positions the float at approximately the same level as a layer containing the target analyte, when the tube, float and sample are centrifuged. Prior to isolation, the material may be located between an outer surface of the float and an inner surface of the tube, or within a central bore that extends longitudinally through the float. The target analyte may then be drawn into a compartment within the float, thereby isolating the target analyte from the other suspension constituents.
