The EasySep™ Human Th17 Enrichment Kit is a two-step method designed to enrich human Th17 cells from fresh peripheral blood nucleated cells. CD4+CXCR3- T cells are first pre-enriched by negative selection using EasySep™ Human CD4+CXCR3- T Cell Pre-Enrichment Cocktail. Unwanted cells are targeted for removal with Tetrameric Antibody Complexes (TAC) recognizing CD8, CD14, CD16, CD19, CD20, CD36, CD56, CD66b, CD123, TCRγ/δ, glycophorin A, CD45RAhigh, CXCR3 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. Following pre-enrichment, CCR6 positive CD4+CXCR3- T cells are selected using EasySep™ Human CCR6 Positive Selection Cocktail. Cells are targeted with TAC recognizing CCR6 and dextran-coated magnetic particles. Labeled cells are separated using an EasySep™ magnet and remain in the tube while the unwanted cells are poured off.

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.

Data and Publications


Start: 54% CD4+CXCR3-CCR6+ T Cells

Figure 1. Typical EasySep™ Human Th17 Cell Enrichment Profile

Starting with fresh PBMCs, the Th17 (CD4+CXCR3-CCR6+) cell content of the isolated fraction is typically 85 - 94%. In the above example, the purities of the start, pre-enriched, and final enriched fractions are 5.4%, 47.4%, and 91.4%, respectively. Intracellular staining for IL-17-producing cells typically ranges from 5 - 20% IL-17+ cells. These values vary widely among donors. IFN-γ-producing cells are typically < 5% of the enriched fraction.
