The EasySep™ Human Neutrophil Enrichment Kit is designed to isolate neutrophils from a polymorphonuclear cell-rich fraction of peripheral blood by negative selection. Unwanted cells are targeted for removal with Tetrameric Antibody Complexes recognizing CD2, CD3, CD9, CD19, CD36, CD56, glycophorin A and dextran-coated magnetic particles. Labeled cells are separated using an EasySep™ magnet without the use of columns. Desired cells are poured off into a new tube. The enrichment kit is compatible with cells prepared using HetaSep™ (Catalog #07906) sedimentation or red blood cell lysis.
