Abstract:
1. A method of isolating a fraction of interest from a physiological sample, comprising steps of: providing a container comprising a plurality of reservoirs supported in a rigid exoskeleton, wherein one of said reservoirs comprises an elongated flexible reservoir which is narrower relative to at least one other reservoir; placing a physiological fluid sample comprising a plurality of cells in said container; separating said plurality of cells in the container into distinct relative density fractions by sedimentation; orienting said container vertically; exposing said elongated flexible reservoir and causing relative movement between said elongated flexible reservoir and a clamp to locate a fraction of interest among said density fractions retained in said elongated flexible reservoir; isolating said fraction of interest retained in said elongated flexible reservoir by clamping a region of the elongated flexible reservoir adjacent the located fraction of interest; and withdrawing said fraction of interest by inserting a cannula into said elongated flexible reservoir.
