Abstract:
A method of separating a target cell-containing sample into a substantially target cell-depleted portion, and a target cell-containing portion comprising at least one of a stem cell, a lymphocyte, and a leukocyte, comprising:receiving the sample in a vessel, wherein the vessel retains the sample within a plurality of confining walls, and wherein at least one of the confining walls is flexible; providing an additive and magnetic particles, wherein the additive binds to the at least one of the stem cell, lymphocyte, and leukocyte, and the magnetic particles, and wherein the magnetic particles bind to the at least one of the stem cell, lymphocyte, and leukocyte, and the additive; combining the sample, the additive, and the magnetic particles to produce a target cell-containing network; and separating the network within the plurality of confining walls from the target cell-depleted portion by applying a first and a second force, wherein the first force is a magnetic force and the second force is an automatic mechanical force that is transmitted through at least one of the confining walls.
