Dynabeads™ CD19 Pan B (Invitrogen™)

Dynabeads® CD19 Pan B are superparamagnetic beads covalently coupled with an anti-human CD19 antibody that enable easy isolation or depletion of human CD19+ B cells directly from whole blood, bone marrow, buffy coat, mononuclear cells (MNC), and tissue digests. Advantages of Dynabeads® CD19 Pan B:

• Fast and efficient isolation of CD19+ B cells from any sample—no columns required
• High purity, yield, and viability of positively isolated CD19+ cells for molecular downstream assays or efficient depletion of CD19+ B cells
• Fast and efficient depletion of CD19+ T cells from any sample

About Dynabeads® CD19 Pan B
Dynabeads® CD19 pan B are uniform (4.5 µm diameter) superparamagnetic beads coated with a primary monoclonal antibody specific for the CD19 membrane antigen mainly expressed on human B cells. Because of the bead size, Dynabeads® CD19 pan B can easily and efficiently isolate or deplete cells from viscous samples such as whole blood and bone marrow in about 30 minutes. Dynabeads® CD19 pan B 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 CD19+ cells for cell-based applications, or you need to check your samples with flow cytometry, you can combine with DETACHaBEAD® CD19 (purchased separately to get bead- and antibody-free cells) or use Dynabeads® Untouched™ Human B Cells to obtain untouched human B cells.

Magnetic bead-based separation offers easy handling
Dynabeads® CD19 Pan B 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™ Regulatory CD4+/CD25+ T Cell Kit (Invitrogen™)

Use this kit to isolate highly pure CD4+ CD25+ regulatory T-cells (Treg) that express the intracellular transcription factor Foxp3. The CD4+ CD25- cell fraction can be used as effector cells in downstream inhibitory assays. You can expect >95% purity (CD4+ CD25+ expression) and >80% Foxp3 expression.

Isolate bead- and antibody-free human CD4+ CD25+ Foxp3+ Treg cells

Treg cells can be expanded with Dynabeads® CD3/CD28 Treg Expander and remain
Foxp3+.

Treg cells can be used in any downstream applications (e.g., suppression assays)

Methodology

The isolation procedure includes the following steps:

• Negative isolation of untouched human CD4+ T-cells from PBMC.
• Positive isolation of CD25+ T-cells from the untouched CD4+ T-cell subset.
• Removal of beads from the CD4+CD25+ Treg cells with DETACHaBEAD®.

Starting sample: PBMC

Dynabeads™ Untouched™ Human B Cells Kit (Invitrogen™)

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

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

An antibody mix towards the non-B 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 B cells can be directly analyzed in a flow cytometer and used in any application.

Excellent Yield, Purity, and Viability of Recovered Cells
Dynabeads® CD2 are uniform, superparamagnetic beads (4.5 µm diameter) that enable easy isolation of human CD2+ cells directly from any sample. Dynabeads® CD2 beads are coated with a primary monoclonal antibody specific for the CD2 membrane antigen mainly expressed on human T-cells and natural killer (NK) cells. Dynabeads® CD2 bind to CD2+ 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 CD2+ cells.

Ideal for Both Depletion and Positive Isolation for Downstream Molecular Assays
Because of the powerful magnets used for separation, Dynabeads® CD2 can be used in viscous samples such as whole blood and bone marrow, thereby providing a convenient method for the efficient depletion of CD2+ cells in about 30 minutes. Dynabeads® CD2 will also afford excellent recovery of high-purity, viable cells when used for positive isolation for 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 T-cells for cell-based applications, or you need to check your samples with flow cytometry, use Dynabeads® FlowComp™ Human CD3 (for bead-free cells) or Dynabeads® Untouched™ Human T Cells to obtain untouched human T cells.
