Overview

The Complete Processing Kit for whole blood uses EasySep™ HLA T Cell Enrichment Kit to isolate human T cells from HetaSep™-treated whole blood by negative selection. Unwanted cells are targeted for removal with tetrameric antibody complexes recognizing non-T cells 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.
Advantages:
• Fast, easy-to-use and column-free
• Up to 98% purity
• Untouched, viable cells
• Compatible with downstream HLA assays

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.

FACS Histogram Results with EasySep™ HLA Whole Blood T Cell Enrichment Kit

Figure 1. FACS Histogram Results with EasySep™ HLA Whole Blood T Cell Enrichment Kit

Starting with HetaSep™-treated whole blood, the CD3+ cell content of the enriched fraction typically ranges from 93.1 - 98.0% (gated on CD45+ cells). Starting with 0.5 mL of HetaSep™-treated whole blood (equivalent to 5 mL of whole blood), 1.1 - 3.1 x 10e6 CD3+ cells are typically recovered.
