Description

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.
