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).

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.

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

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

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

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

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.

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

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.

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

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.

Figure 1. Typical EasySep Human Nave CD4+ T Cell Isolation Profile

Starting with a single-cell suspension of PBMCs, the nave CD4+ T cell (CD3+CD4+CD45RA+CD45RO-) content of the isolated fraction typically ranges from 91.3% - 96.9%. In the example above, the purities of the start and isolated fraction are 11.1% and 93.2%, respectively.

Bjö et al.

Staphylococcus aureus (S. aureus) is a human pathogen as well as a frequent colonizer of skin and mucosa. This bacterium potently activates conventional T-cells through superantigens and it is suggested to induce T-cell cytokine-production as well as to promote a regulatory phenotype in T-cells in order to avoid clearance. This study aimed to investigate how S. aureus impacts the production of regulatory and pro-inflammatory cytokines and the expression of CD161 and HELIOS by peripheral CD4(+)FOXP3(+) T-cells. Stimulation of PBMC with S. aureus 161:2-cell free supernatant (CFS) induced expression of IL-10, IFN- and IL-17A in FOXP3(+) cells. Further, CD161 and HELIOS separated the FOXP3(+) cells into four distinct populations regarding cytokine-expression. Monocyte-depletion decreased S. aureus 161:2-induced activation of FOXP3(+) cells while pre-stimulation of purified monocytes with S. aureus 161:2-CFS and subsequent co-culture with autologous monocyte-depleted PBMC was sufficient to mediate activation of FOXP3(+) cells. Together, these data show that S. aureus potently induces FOXP3(+) cells and promotes a diverse phenotype with expression of regulatory and pro-inflammatory cytokines connected to increased CD161-expression. This could indicate potent regulation or a contribution of FOXP3(+) cells to inflammation and repression of immune-suppression upon encounter with S. aureus.
