Overview

The EasySep™ Mouse Memory CD4+ T Cell Isolation Kit is designed to isolate pan-memory CD4+ T cells from single-cell suspensions of splenocytes or other tissues by negative selection. Unwanted cells are targeted for removal with biotinylated antibodies directed against non-memory CD4+ T cells (CD8, CD11b, CD11c, CD19, CD24, CD45R, CD45RB, CD49b, CD105 and TCRγ/δ) and streptavidin-coated magnetic particles (RapidSpheres™ ). 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™ Streptavidin RapidSpheres™ be used for either positive or negative selection?

Currently, EasySep™ Streptavidin RapidSphere™ kits are only available for negative selection and work by targeting and removing unwanted cells.

How does the separation work?

Streptavidin RapidSphere™ magnetic particles are crosslinked to unwanted cells using biotinylated antibodies. When placed in the EasySep™ Magnet, labeled cells migrate to the wall of the tube. The unlabeled cells are then poured off into a new tube.

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™ Streptavidin RapidSphere™ separations be automated?

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

Are cells isolated using EasySep™ RapidSphere™ products FACS-compatible?

Yes. Desired cells are unlabeled and ready to use in downstream applications, such as FACS analysis.

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.

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 EasyPlate™ EasySep™ magnet?

19051 (T Cells), 19052 (CD4 T cells), 19157 (Memory CD4 T Cells), 19053 (CD8 T Cells), 19054 (B Cells), 19254 (Naïve B cells), 19055 (NK Cells), 19058 (Monocytes without CD16 depletion), 19059 (Monocytes)

Typical EasySet™ Mouse Memory CD4+ T Cell Isolation Profile

Figure 1. Typical EasySet™ Mouse Memory CD4+ T Cell Isolation Profile

Starting with mouse splenocytes, the memory CD4+ T cell (CD4+CD62L high CD44 high/int central memory and CD4+CD62L-CD44 high/int effector memory) content of the isolated fraction typically ranges from 78 - 96%. In the example above, the final purities of the start and isolated fractions are 5.3% and 90.2%, respectively.
