Magnetic bead separation technology is based on the specific binding between cell-surface markers (such as CD3, CD4, CD8, CD19, etc.) and antibody–bead complexes. Using a magnetic field, target cells are isolated from heterogeneous cell populations to achieve high-purity enrichment or depletion, thereby providing high-quality cell samples for downstream functional studies and cell-therapy manufacturing.

Simple Operating Procedure
① Sample Preparation — Peripheral blood, spleen, lymph nodes, bone marrow, tumor tissue, or cultured cells: prepare into a single-cell suspension and count.
② Antibody Labeling — Add the antibody labeling reagent and incubate.
③ Bead Binding — Add the magnetic beads and incubate.
④ Magnetic Separation — Place on the cell-separation magnet; separate and discard the labeled non-target cells, then collect the target cells.
⑤ Harvest — Centrifuge and resuspend; proceed directly to downstream experiments.
Launch of the first four negative-selection kits
This release includes four human cell-separation kits, all based on a column-free negative-selection protocol: human CD3⁺ T cells, human CD4⁺ T cells, human CD8⁺ T cells, and human B cells.
