In this negative-selection process, non-Human Naïve CD4 T cells are labeled with biotin-conjugated antibodies, and the cells are then incubated with streptavidin-nanomagnetic beads. As a result, the unwanted cells become bound to the magnetic beads via the antibody‑bead complex, while the target Human Naïve CD4 T cells remain unlabeled. The cell suspension is subsequently loaded onto the separation column; under the influence of a magnetic field, the magnetically labeled non-target cells are retained within the column, whereas the unlabeled Human Naïve CD4 T cells elute by gravity into the collection tube. The resulting supernatant represents the enriched fraction of Human Naïve CD4 T cells after removal of the non-target cells.\u003c\/span\u003e\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 22%;\"\u003e\u003cstrong\u003eApplications in cell sorting\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 78%;\"\u003eNaïve CD4 T cells in their unmanipulated, label-free state are isolated from human PBMCs and can be used for a variety of downstream functional assays.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 22%;\"\u003e\u003cstrong\u003eReactivity\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 78%;\"\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 22%;\"\u003e\u003cstrong\u003eMagnetic Bead Size\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 78%;\"\u003e20 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 22%;\"\u003e\u003cstrong\u003eSeparation Method\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 78%;\"\u003eColumn-Based\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 22%;\"\u003e\u003cstrong\u003eSelection Strategy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 78%;\"\u003eNegative Selection\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"width: 22%;\"\u003e\u003cstrong\u003eStability \u0026amp; Storage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 78%;\"\u003e\u003cp\u003eStore protected from light at 2–8 °C; do not freeze.\u003c\/p\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003c\/div\u003e\u003ch4\u003eBackground\u003c\/h4\u003e\u003cdiv\u003e\u003cp\u003e\u003cspan\u003eThe immunophenotype of human naïve CD4 T cells is CD3⁺CD4⁺CD45RA⁺CD45RO⁻. They constitute the core precursor population of helper T cells in the human adaptive immune system, responsible for initial antigen recognition and directed differentiation, and are also a key cell subset for maintaining immune homeostasis, mediating specific responses, and establishing immunological memory. The human naïve CD4 T-cell negative-selection kit is developed based on immuno-magnetic bead–mediated negative selection, overcoming the labeling limitations inherent in positive-selection methods. By specifically depleting non-target cells—such as CD8 T cells, NK cells, B cells, monocytes, dendritic cells, granulocytes, and memory T cells—it yields unlabeled, native-state, highly purified naïve CD4 T cells, perfectly preserving their initial quiescent state, surface molecule integrity, and multipotential differentiation capacity. This makes them suitable for various functional assays, including in vitro activation and proliferation, subtype-directed differentiation induction, and cytokine secretion analysis, and they have become the mainstream research tool for isolating human naïve CD4 T cells.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e\u003ch4\u003eProtocol\u003c\/h4\u003e\u003cdiv\u003e\n\u003cspan style=\"display:inline; white-space:nowrap;\"\u003eNote: This kit does not include sorting buffer; please provide it separately.
