HetaSep Solution, 100mL

For immunology research requiring clean leukocyte preparations, this 100 mL bottle of 6% hetastarch sedimentation reagent from STEMCELL Technologies (HetaSep Solution) enables rapid erythrocyte removal from whole blood. The hydroxyethyl starch polymer induces red blood cell aggregation, producing a clear leukocyte-rich upper phase after a short room-temperature incubation. Researchers harvest the supernatant to obtain lymphocytes, monocytes, and granulocytes with reduced red blood cell contamination for downstream flow cytometry, cell culture, and immunohistochemistry workflows. The reagent is intended for in vitro research use only and is commonly applied in hematology, immunology, and transplantation studies where intact white blood cell populations must be recovered from anticoagulated whole blood without density-gradient centrifugation.
