Application

SOLIDEX®-ISOEx Untouched Human CD8+ T Cell Isolation Kit (Column-based) is used for Negative CD8+ T Cell Isolation (Untouched), with the Key Features, such as Preserves native cell function; maintains surface marker integrity; ideal for functional studies

Protocol

  1. Preparation: Prepare a single-cell suspension from cryopreserved or fresh PBMCs.
  2. Labeling: Add the Biotin-Antibody Cocktail (targets non-CD8+ cells) to the cell suspension. Incubate.
  3. Bead Binding: Add Anti-Biotin Microbeads to bind the labeled non-target cells. Incubate.
  4. Separation: Apply the suspension to the separation column placed in a magnetic field.
  5. Elution: Unlabeled CD8+ T cells pass through the column freely and are collected in the flow-through fraction (Untouched).

Validation Data

Efficient Enrichment of High-Purity CD8+ T Cells from Human PBMCs Using SOLIDEX®-ISOEx Untouched Human CD8+ T Cell Isolation Kit (Column-based)

Catalog No. GM-CD8-T-Cell-iso-kit
To evaluate the isolation efficiency of the SOLIDEX®-ISOEx Untouched Human CD8+ T Cell Isolation Kit (Column-based), CD8+ T cells were enriched from human peripheral blood mononuclear cells (hPBMCs) via negative selection. Non-target cells were labeled with a biotinylated antibody cocktail and depleted using magnetic beads within a separation column.
Cell fractions were stained with CD3-APC and CD8-PE for flow cytometric analysis. The frequency of CD8+ T cells demonstrated a substantial increase from 22.6% in the pre-isolation sample to 91.9% in the post-isolation fraction. These results confirm that the column-based system provides superior depletion of non-target populations, yielding highly purified "untouched" CD8+ T cells.

Background

Why Choose SOLIDEX®-ISOEx Untouched Human CD8+ T Cell Isolation Kit?

  • 100% Untouched Cells: Target CD8+ T cells are never bound by antibodies or beads, preventing receptor blocking and accidental activation.
  • Superior Purity: Column-based separation acts as a physical filter, significantly reducing background contamination compared to column-free methods.
  • High Viability: Gentle isolation preserves the metabolic health of cytotoxic T cells for sensitive functional assays.
  • Fast & Simple: Streamlined protocol allows for isolation in under 45 minutes.

FAQ

What are the sample requirements?
We recommend using fresh or cryopreserved Human PBMCs. For best results, ensure cell viability is >90% before starting. Leukapheresis products are also compatible.
Can I stain the cells for Flow Cytometry immediately after isolation?
Yes. Since this is an "Untouched" (Negative Selection) kit, the CD8 receptors on the surface of your target cells are free and not blocked by any magnetic beads or antibodies. You can proceed directly to staining.
How does the Column-based separation work?
The column contains a ferromagnetic matrix. When placed in a magnetic field, it amplifies the magnetic force, effectively retaining the magnetically labeled non-target cells. The unlabeled CD8+ T cells simply pass through.
Are the separation columns reusable?
No. The columns are designed for single-use to ensure maximum sterility and prevent cross-contamination between patient samples.
What is the advantage of Column-based over Column-free methods?
Column-based methods typically offer higher purity. The column matrix allows for thorough washing of the retained cells, ensuring that only the specific "Untouched" cells pass through, whereas column-free methods can sometimes suffer from non-specific entrapment or lower purity in complex samples.
Is this protocol compatible with automated systems?
Yes, the SOLIDEX®-ISOEx column format is compatible with most standard automated magnetic separation instruments designed for column-based protocols.
