The EasySep™ Human Pan-DC Pre-Enrichment Kit is designed to pre-enrich all dendritic cells (DCs) (including myeloid and plasmacytoid DCs) from fresh or previously frozen peripheral blood mononuclear cells by negative selection. Unwanted cells are targeted for removal with Tetrameric Antibody Complexes recognizing non-pan DCs and dextran-coated magnetic particles. The labeled cells are separated using an EasySep™ magnet without the use of columns. Desired cells are poured off into a new tube.

Frequently Asked Questions

Can EasySep™ be used for either positive or negative selection?

Yes. The EasySep™ kits use either a negative selection approach by targeting and removing unwanted cells or a positive selection approach targeting desired cells. Depletion kits are also available for the removal of cells with a specific undesired marker (e.g. GlyA).

How does the separation work?

Magnetic particles are crosslinked to cells using Tetrameric Antibody Complexes (TAC). When placed in the EasySep™ Magnet, labeled cells migrate to the wall of the tube. The unlabeled cells are then poured off into a separate fraction.

Which columns do I use?

The EasySep™ procedure is column-free. That's right - no columns!

How can I analyze the purity of my enriched sample?

The Product Information Sheet provided with each EasySep™ kit contains detailed staining information.

Can EasySep™ separations be automated?

Yes. RoboSep™, the fully automated cell separator, automates all EasySep™ labeling and cell separation steps.

Can EasySep™ be used to isolate rare cells?

Yes. We recommend a cell concentration of 2x108 cells/mL and a minimum working volume of 100 µL. Samples containing 2x107 cells or fewer should be suspended in 100 µL of buffer.

Are the EasySep™ magnetic particles FACS-compatible?

Yes, the EasySep™ particles are flow cytometry-compatible, as they are very uniform in size and about 5000X smaller than other commercially available magnetic beads used with column-free systems.

Can the EasySep™ magnetic particles be removed after enrichment?

No, but due to the small size of these particles, they will not interfere with downstream applications.

Can I alter the separation time in the magnet?

Yes; however, this may impact the kit's performance. The provided EasySep™ protocols have already been optimized to balance purity, recovery and time spent on the isolation.

For positive selection, can I perform more than 3 separations to increase purity?

Yes, the purity of targeted cells will increase with additional rounds of separations; however, cell recovery will decrease.

How does the binding of the EasySep™ magnetic particle affect the cells? is the function of positively selected cells altered by the bound particles?

Hundreds of publications have used cells selected with EasySep™ positive selection kits for functional studies. Our in-house experiments also confirm that selected cells are not functionally altered by the EasySep™ magnetic particles.

If particle binding is a key concern, we offer two options for negative selection. The EasySep™ negative selection kits can isolate untouched cells with comparable purities, while RosetteSep™ can isolate untouched cells directly from whole blood without using particles or magnets.

Signaling Cascade through DC-ASGPR Induces Transcriptionally Active CREB for IL-10 Induction and Immune Regulation.

C. Gu et al.


The types and magnitude of Ag-specific immune responses can be determined by the functional plasticity of dendritic cells (DCs). However, how DCs display functional plasticity and control host immune responses have not been fully understood. In this study, we report that ligation of DC-asialoglycoprotein receptor (DC-ASGPR), a C-type lectin receptor (CLR) expressed on human DCs, resulted in rapid activation of Syk, followed by PLCgamma2 and PKCdelta engagements. However, different from other Syk-coupled CLRs, including Dectin-1, signaling cascade through DC-ASGPR did not trigger NF-kappaB activation. Instead, it selectively activated MAPK ERK1/2 and JNK. Rapid and prolonged phosphorylation of ERK1/2 led to sequential activation of p90RSK and CREB, which consequently bound to IL10 promoter and initiated cytokine expression. In addition, DC-ASGPR ligation activated Akt, which differentially regulated the activities of GSK-3alpha/beta and beta-catenin and further contributed to IL-10 expression. Our observations demonstrate that DC-ASGPR induces IL-10 expression via an intrinsic signaling pathway, which provides a molecular explanation for DC-ASGPR-mediated programing of DCs to control host immune responses.

Diversification of human plasmacytoid predendritic cells in response to a single stimulus.

Alculumbre SG et al.


Innate immune cells adjust to microbial and inflammatory stimuli through a process termed environmental plasticity, which links a given individual stimulus to a unique activated state. Here, we report that activation of human plasmacytoid predendritic cells (pDCs) with a single microbial or cytokine stimulus triggers cell diversification into three stable subpopulations (P1-P3). P1-pDCs (PD-L1+CD80-) displayed a plasmacytoid morphology and specialization for type I interferon production. P3-pDCs (PD-L1-CD80+) adopted a dendritic morphology and adaptive immune functions. P2-pDCs (PD-L1+CD80+) displayed both innate and adaptive functions. Each subpopulation expressed a specific coding- and long-noncoding-RNA signature and was stable after secondary stimulation. P1-pDCs were detected in samples from patients with lupus or psoriasis. pDC diversification was independent of cell divisions or preexisting heterogeneity within steady-state pDCs but was controlled by a TNF autocrine and/or paracrine communication loop. Our findings reveal a novel mechanism for diversity and division of labor in innate immune cells.

Human blood BDCA-1 dendritic cells differentiate into Langerhans-like cells with thymic stromal lymphopoietin and TGF-β.

Martí et al.


The ontogeny of human Langerhans cells (LCs) remains poorly characterized, in particular the nature of LC precursors and the factors that may drive LC differentiation. Here we report that thymic stromal lymphopoietin (TSLP), a keratinocyte-derived cytokine involved in epithelial inflammation, cooperates with transforming growth factor (TGF)-β for the generation of LCs. We show that primary human blood BDCA-1(+), but not BDCA-3(+), dendritic cells (DCs) stimulated with TSLP and TGF-β harbor a typical CD1a(+)Langerin(+) LC phenotype. Electron microscopy established the presence of Birbeck granules, an intracellular organelle specific to LCs. LC differentiation was not observed from tonsil BDCA-1(+) and BDCA-3(+) subsets. TSLP + TGF-β LCs had a mature phenotype with high surface levels of CD80, CD86, and CD40. They induced a potent CD4(+) T-helper (Th) cell expansion and differentiation into Th2 cells with increased production of tumor necrosis factor-α and interleukin-6 compared with CD34-derived LCs. Our findings establish a novel LC differentiation pathway from BDCA-1(+) blood DCs with potential implications in epithelial inflammation. Therapeutic targeting of TSLP may interfere with tissue LC repopulation from circulating precursors.
