The Easy 50 EasySep™ Magnet is designed for cell separation procedures using selected EasySep™ reagents when processing a large number of cells (up to 4 x 10^9 cells). The Easy 50 EasySep™ Magnet generates a high-gradient magnetic field in the interior cavity that is strong enough to separate cells labeled with magnetic EasySep™ particles without the use of columns. The Easy 50 EasySep™ Magnet is designed to hold a standard 50 mL conical tube.

Frequently Asked Question
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.
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.
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.
Which cell separation kits are compatible with the "Easy 50" EASYSEP™ magnet?
At present, the "Easy 50" EasySep™ magnet is only compatible with EasySep™ kits for human cell separation.
