• Deplete any target cell from all species, except mouse
• Isolate cells directly from whole blood for molecular applications
• Use a cocktail of mouse IgG's to deplete unwanted labeled cells and obtain untouched, bead and antibody-free cells.

This Product Contains: 5 ml Dynabeads® coated with goat polyclonal against all mouse IgG subclasses.

Starting samples:
Whole blood, cord blood, MNC, buffy coat, mouse spleen/ lymph nodes, tissue digests.

Dynabeads™ Sheep Anti-Rat IgG (Invitrogen™)

Dynabeads® Sheep Anti-Rat IgG are 4.5 µm superparamagnetic beads with affinity purified polyclonal sheep anti-rat IgG covalently bound to the bead surface. These beads can be used to isolate any cell from any species (except rat), depending on the specificity of the monoclonal rat IgG employed. Dynabeads® Sheep Anti-Rat IgG are especially well suited for cell isolation from mouse samples (cross-reactivity to mouse antibodies is high and cross-reactivity to human antibodies is minimal).

• Works with any cell type, from any sample and from any species (except rat)
• Fast and efficient depletion or positive isolation of any target cell for molecular downstream assays using rat primary antibody
• Obtain pure and untouched cells using a mixture of rat IgGs to deplete unwanted cells

Magnetic bead-based separation offers easy handling
The rat primary antibody may be added to the cell sample (indirect technique) or pre-coated onto the Dynabeads® Sheep Anti-Rat IgG (direct technique). Regardless of which of these techniques is used, when the cell sample and the Dynabeads® Sheep Anti-Rat IgG are mixed, the beads bind to the target cells. Placing the sample on a magnet separates the bead-bound cells from the rest of the sample. One or more rat primary antibodies may be used to either deplete the sample of unwanted cells (negative isolation) or to capture specific cells for molecular downstream experiments (positive isolation). For positive isolation of bead-free cells (e.g., for flow cytometry), we recommend using your rat antibody in combination with the Dynabeads® FlowComp™ Flexi Kit.

Useful for many sample types
Using Dynabeads® Sheep Anti-Rat IgG, you can isolate cells from many starting samples including whole blood, mouse spleen or lymph node cells, and tissue digests.

Dynabeads™ Untouched™ Mouse CD8 Cells Kit (Invitrogen™)

Dynabeads® Untouched™ Mouse CD8 Cells supplies both 4.5 µm superparamagnetic Dynabeads® (with a polyclonal sheep anti-rat IgG antibody covalently bound to the bead surface) and a monoclonal Antibody Mix, together designed for the depletion of CD8-negative leucocytes from mouse spleen or lymph node single-cell suspensions. Following the depletion procedure, the negatively isolated, untouched target mouse CD8+ cells are pure, viable, and ready to be used in any downstream application.

• Rapid isolation of untouched mouse CD8+ T cells—no columns required
• Pure and viable mouse CD8+ T cells are ready for any downstream application

Excellent yield, purity, and viability of recovered cells
The Antibody Mix contains a cocktail of rat IgGs that binds mouse CD4+ T cells, B cells, NK cells, monocytes/macrophages, dendritic cells, erythrocytes, and granulocytes. The Antibody Mix is first added to the sample in a tube to bind the unwanted CD8-negative cells. The cells are then washed to remove excess antibodies. Mouse Depletion Dynabeads® (coated with a rat IgG antibody) are added to bind the antibody-labeled, CD8-negative cells. After a short incubation, the bead-bound cells are then separated from unbound cells in 1–2 minutes using a magnet. The purified target mouse CD8+ cells in the supernatant can be transferred to a new tube for use in any downstream application.

This fast and gentle isolation method does not require the use of columns, and helps ensure high purity, recovery and viability of the untouched CD8+ cells. The protocol can be scaled up according to your sample size.

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
