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.

Dynabeads™ CD8 (Invitrogen™)

Dynabeads® CD8 are superparamagnetic beads coupled with an anti-human CD8 antibody that enable easy isolation or depletion of human CD8+ T cells directly from any sample, including whole blood, bone marrow, buffy coat, mononuclear cells (MNC), and tissue digests. Advantages of Dynabeads® CD8:

• Fast and efficient isolation of CD8+ T cells from any sample—no columns required
• High purity, yield, and viability of positively isolated CD8+ T cells for molecular downstream assays
• Fast and efficient depletion of CD8+ T cells from any sample

About Dynabeads® CD8
Dynabeads® CD8 are uniform, superparamagnetic beads (4.5 µm diameter) coated with a primary monoclonal antibody specific for the CD8 membrane antigen mainly expressed on human cytotoxic T cells. Because of the bead size, Dynabeads® CD8 can easily and efficiently isolate or deplete cells from viscous samples such as whole blood and bone marrow in about 30 minutes. Dynabeads® CD8 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 CD8+ cells for cell-based applications, or you need to check your samples with flow cytometry, check out our total human CD8 product offerings.

Magnetic bead–based separation offers easy handling
Dynabeads® CD8 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.

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.

Dynabeads™ Mouse Pan T (Thy1.2) (Invitrogen™)

Dynabeads® Mouse pan T (Thy 1.2) are magnetic beads that provide a robust and versatile tool to isolate or deplete mouse T-cells directly from any sample, including tissue digests such as spleen or lymph nodes, whole blood, bone marrow, and mononuclear cells (MNC).
• Rapid isolation of mouse T-cells from any sample – no columns required
• Positive isolation for molecular downstream assays or efficient depletion of mouse T cells

Excellent Yield, Purity, and Viability of Recovered Cells
Dynabeads® Mouse pan T (Thy 1.2) are uniform, superparamagnetic beads (4.5 µm diameter) that enable easy isolation of mouse T-cells from spleen or lymph nodes, although any single-cell suspension may be used. Dynabeads® Mouse pan T beads are coated with a primary monoclonal antibody specific for the Thy 1.2 membrane antigen expressed on peripheral T cells, thymocytes and intraepithelial T lymphocytes of all common mouse strains. Dynabeads® Mouse pan T binds to T-cells during a short incubation period in a tube, after which the bead-bound cells are separated from unbound cells using a magnet. This fast and gentle isolation method does not require the use of columns, and helps ensure high purity, recovery and viability of the isolated T cells.

Ideal for Both Depletion and Positive Isolation for Downstream Molecular Assays
Because of the powerful magnets used for separation, Dynabeads® Mouse pan T (Thy 1.2) can be used in viscous samples such as single cell suspensions from tissue, whole blood and bone marrow, and enable efficient depletion of mouse T-cells in about 30 minutes. Dynabeads® Mouse pan T will also afford excellent recovery of high-purity, viable cells when used for positive isolation for downstream studies; for example, those in which cells are to be lysed while still attached to beads, and nucleic acids or proteins further purified. Note intact cells will not be released from these beads, so if you want to isolate mouse T-cells for cell-based applications, or you need to check your samples with flow cytometry, you should use Dynabeads® FlowComp Mouse Pan T (CD90.2) (for bead-free cells).
