BIOASSAY AND BIOMOLECULAR IDENTIFICATION, SORTING, AND COLLECTION METHODS USING MAGNETIC MICROSPHERES

摘要

The present invention provides a process of separating a sample comprising attaching a different receptor agent to at least two distinct populations of magnetic microspheres with a specific range of magnetic moments; combining a target sample with said distinct populations of magnetic microspheres containing different attached receptor agents together for a period of time sufficient to allow for binding between attached receptor agents and target species within said target sample to form one or more receptor agent-target species complexes; and sorting said distinct populations of magnetic microspheres containing different receptor agent-target species complexes by passing through a magnetic separator.
