Dynabeads™ FlowComp™ Flexi Kit Invitrogen™

This gentle, easy-to-use and highly flexible kit allows you to positively isolate bead-free and flow-compatible cells in combination with your own antibody of choice. Now you can isolate practically any cell type from any species or starting sample using your own antibody. Immediately after positive isolation, the beads are released and removed from your cell sample. In this way, you avoid exposing your cells to potentially cytotoxic or immunogenic foreign substances like iron oxides or dextrans, a potential problem when working with biodegradable particles. In addition, your cells will not be exposed to the stress of being passed through a column.

The kit supplies you with everything you need for DSB-X™ biotinylation of your antibodies and subsequent isolation of your cell type of interest. This technology has been successfully used to isolate a number of cell subsets including human and mouse T cells, B cells, NK cells, monocytes, and endothelial cells.

Advantages:

• Combine with your antibody of choice to isolate any cell type
• No risk of your results being affected by the isolation method
• Gentle tube-based method - no columns needed
• High purity, recovery and viability
• Bead-free cells - compatible with flow cytometry analysis or for direct use in any cell-based assay

Starting sample:
Whole blood, PBMC/MNC, single cell suspensions from lymph nodes, spleen or other tissues.

Capacity:
The kit will process 2 x 109 mononuclear cells (MNC). Please note that the choice of antibody clone is of key importance for successful isolation (see package insert for technical recommendations).

Concentration:
Supplied at 15 mg beads per ml in phosphate buffered saline (PBS), pH 7.4, containing 0.1% bovine serum albumin (BSA) and 0.02% sodium azide.

Dynabeads™ Untouched™ Human NK Cells Kit Invitrogen™

Use this kit to isolate pure and viable untouched NK cells from PBMC by negative isolation. The kit depletes T cells, B cells, monocytes, platelets, dendritic cells, granulocytes and erythrocytes. The negatively isolated human NK cells are left in the sample and have not been in contact with the Dynabeads. The bead and antibody-free NK cells are truly untouched, and in perfect shape for any functional assay and application.

• High purity, recovery and viability of human untouched NK cells
• Easy to use and to scale up
• No columns required

Methodology:
An antibody mix towards the non-NK cells is added to the sample and allowed to bind to the cells. Dynabeads® are added and will bind to the antibody-labeled cells during a short incubation. The bead-bound cells are quickly separated on a magnet and discarded. The remaining negatively isolated and untouched human NK cells can be directly analyzed in a flow cytometer and used in any application.

Starting Sample:
PBMC

MagniSort™ Human CD4 T cell 2-Step Enrichment Kit Invitrogen™

The MagniSort™ Human CD4 2-Step Enrichment Kit is designed for the magnetic separation of CD4+ T cells by positive selection after first depleting monocytes. It has been optimized for the isolation of CD4+ T cells from human peripheral blood monocuclear cells, utilizing biotinylated Anti-Human CD14 and Anti-Human CD4 antibodies, as well as streptavidin-coated magnetic beads. In the first step, monocytes are bound by Anti-Human CD14 antibody and then magnetic beads. When placed in a magnetic field, the monocytes are held in the magnet while the remaining cells are decanted and used for the second step. In the second step, the monocyte-depleted cells are bound by Anti-Human CD4 antibody and then magnetic beads. Now, when placed in the magnetic field, the CD4+ T cells are held in the magnet while undesired cells can be decanted.

After enrichment, the purity of selected cells can be verified by staining with Anti-Human CD4, clones OKT4 or SK3.

Dynabeads™ CD15 Invitrogen™

Dynabeads® CD15 are superparamagnetic beads covalently coupled with an anti-human CD15 antibody that efficiently depletes human CD15+ myeloid cells (predominantly neutrophil and eosinophil granulocytes) directly from whole blood, buffy coat, or PBMC samples. Dynabeads® CD15 can also be used to positively isolate CD15+ cells for molecular applications. Advantages of Dynabeads® CD15:

• Efficient depletion of granulocytes (neutrophils and eosinophils)
• Isolation of granulocytes directly from whole blood for molecular applications
• No columns required

About Dynabeads® CD15
Dynabeads® CD15 are uniform, superparamagnetic polystyrene beads (4.5 µm diameter) coated with a monoclonal mouse IgM antibody recognizing the human CD15 membrane antigen. The CD15 antigen is predominantly expressed on human neutrophil and eosinophil granulocytes, and to a varying degree on monocytes.

Magnetic bead-;based separation offers easy handling
Dynabeads® CD15 is added to the sample under continuous mixing to optimize the binding of the Dynabeads® to the target cells. By placing the sample on a magnet, it separates the bead-bound target cells from the rest of the sample in just 1–2 minutes. For depletion, remove the supernatant to a new tube for further studies and discard the bead-bound cells. For positive isolation for molecular studies, remove the supernatant and wash the bead-bound cells 2–3 times in buffer to get optimal purity. The cells can be lysed while still attached to the beads and the supernatant transferred to a new tube for downstream molecular analysis. Starting samples can be whole blood, PBMC, or buffy coat.

Dynabeads™ Human T-Activator CD3/CD28 for T Cell Expansion and Activation Gibco™

Dynabeads® Human T-Activator CD3/CD28 are for the activation and expansion of human T cells. Advantages of Dynabeads® Human T-Activator CD3/CD28:

• Activation of T cells without the need for feeder cells
• Activated cells that retain in vivo-like function
• Maximum reproducibility without contamination by soluble antibodies or mitogens
• From 100- to 1,000-fold T cell expansion

About Dynabeads® Human T-Activator CD3/CD28
Dynabeads® Human T-Activator CD3/CD28 offer a simple method for activation and expansion of T cells that does not require feeder cells (antigen-presenting cells) or antigen. The uniform 4.5 µm diameter, inert, superparamagnetic beads are similar in size to antigen-presenting cells, and are covalently coupled to anti-CD3 and anti-CD28 antibodies. These two antibodies provide primary and co-stimulatory signals, optimized for efficient T cell activation and expansion. Expansion of the T cell population can be stimulated using recombinant IL-2, and after activation or expansion, the magnetic beads can be easily removed using a DynaMag™ magnet. For expansion of antigen-specific T cells from T cell clones or T cell lines, we recommend using Dynabeads® Human T-Activator CD3/CD28/CD137.

Starting samples
Start with mononuclear cells (MNCs)/peripheral blood mononuclear cells (PBMCs) from either whole blood or buffy coat, or T cell subsets including CD3+ T cells, CD4+ or CD8+ T cells, or regulatory T cells.

Downstream applications
The activated T cells can be analyzed shortly after activation (for transfection/transduction or to study TCR signaling, proteomics, gene expression, etc.). T cells can be left in culture to differentiate into T helper cell subsets or expansion of polyclonal/antigen-specific T cells.
