Dynabeads™ CD4 (Invitrogen™)

Dynabeads® CD4 are superparamagnetic beads coupled with an anti-human CD4 antibody that enable easy isolation or deplettion of human CD4+ T cells directly from any sample, including whole blood, bone marrow, buffy coat, mononuclear cells (MNC), and tissue digests. Advantages of Dynabeads® CD4:

• Fast and efficient isolation of CD4+ T cells from any sample—no columns required
• High purity, yield, and viability of positively isolated CD4+ T cells for molecular downstream assays
• Fast and efficient depletion of CD4+ T cells from any sample

About Dynabeads® CD4
Dynabeads® CD4 are uniform, superparamagnetic beads (4.5 µm diameter) coated with a primary monoclonal antibody specific for the CD4 membrane antigen mainly expressed on human T helper cells. Because of the bead size, Dynabeads® CD4 can easily and efficiently isolate or deplete cells from viscous samples such as whole blood and bone marrow in about 30 minutes. Dynabeads® CD4 will also afford excellent recovery of high-purity, viable cells for use in downstream molecular studies; for example, those in which cells are to be lysed while still attached to beads, and nucleic acids or proteins further purified. Note that intact cells will not be released from these beads, so if you want to isolate CD4+ cells for cell-based applications, or you need to check your samples with flow cytometry, check out our total human CD4 product offerings.

Magnetic bead–based separation offers easy handling
Dynabeads® CD4 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, buffy coat, bone marrow, PBMC, or tissue digests.

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™ Untouched™ Human CD8 T Cells Kit (Invitrogen™)

The Dynabeads® Untouched™ Human CD8 T Cells Kit is used to isolate pure and viable untouched CD8+ T cells from PBMC by negative isolation. The kit depletes CD4+ T cells, B cells, NK cells, monocytes, platelets, dendritic cells, granulocytes, and erythrocytes. The negatively isolated human CD8+ T-cells are left in the sample and have not been in contact with the Dynabeads®. The bead- and antibody-free CD8+ T cells are truly untouched, and in perfect shape for any functional assay or application.

Advantages of the Dynabeads® Untouched™ Human CD8 T Cells Kit:

• High purity, recovery, and viability of human untouched CD8+ T cells
• Easy to use and to scale up
• No columns required

Magnetic bead-based Separation offers easy handling
An antibody mix towards the non-CD8 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 CD8+ T cells can be directly analyzed in a flow cytometer and used in any application. For depletion or positive isolation of CD8+ cells, select from our range of Human CD8+ T Cell Isolation Products.

Dynabeads™ FlowComp™ Human CD4 Kit (Invitrogen™)

This gentle and easy-to-use kit allows you to isolate flow-compatible human CD4+ T-cells from PBMC or directly from whole blood. 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.
You can expect a purity level of >95% and up to 75% recovery of human CD4+ cells.

Advantages:

• No risk of your results being affected by the isolation method
• Gentle tube-based method - no columns needed
• High purity and recovery
• Bead-free cells - compatible with flow cytometry analysis
• Viable, bead-free CD4+ T-cells for direct use in any cell-based assay.

The isolated cells have the presumed profile of memory and naive CD4+ T cells, and show a high proliferating and functional capacity. This kit avoids contamination of your isolated CD4+ cells with CD14+ monocytes. You will save time and money, and get increased confidence in your results.

Starting sample: MNC or whole blood

Capacity:
The kit will process 2 × 109 mononuclear cells (MNC) or 80 ml whole blood.
