Isolate highly purified CD33+ and CD66b+ myeloid cells, including myeloid progenitor cells, granulocytes, and monocytes, from fresh whole blood prior to chimerism testing. Desired cells are targeted with tetrameric antibody complexes recognizing CD33, CD66b, and dextran-coated magnetic particles, and separated without the use of columns through immunomagnetic positive selection using an EasySep™ magnet. Cells of interest remain in the tube while unwanted cells are poured off. This product can be used with RoboSep™ to automate immunomagnetic cell isolation. Visit www.EasySep.com for more information.
