Peripheral blood values expressed as cells/µL of blood. Spleen and bone marrow values expressed as % of total splenocytes or bone marrow cells. 4. EasySep™/RoboSep™ Immunomagnetic Isolation. 5. Negative selection labels unwanted cells to isolate desired untouched cells. 6. Positive selection labels and isolates desired cell types. 7. Without CD43 depletion; for pan-B cells. Isolate Cells In As Little As 15 Minutes CELL ISOLATION BY Isolate immune and stem/progenitor cells quickly and easily with column-free platforms from STEMCELL Technologies. EasySep™ and fully automated RoboSep™ enable immunomagnetic cell isolation from virtually any source.
