Evaluation of Lamination Micro Mixer for Micro Immunomagnetic Cell Sorter

A split-and-recombine lamination mixer for μ-immunomagnetic cell sorting system has been developed for extracting stem cells from peripheral blood. Cell suspension is mixed with antibody-coated magnetic beads, and target cells are labeled with antigen-antibody reaction. In this report, the mixer performance is evaluated quantitatively by using human umbilical vein endothelial cells (HUVEC). The number of magnetic beads attached to the target cell is evaluated in two different arrangements of the mixer units.
