EasySep™ Cell Isolation & Cell Separation Technology

A Smarter, More Efficient Way to Isolate Cells

Working efficiently is key to overcoming the demands of scientific research. That’s why our scientists developed a smarter, more efficient way to isolate cells. EasySep™ combines the specificity of monoclonal antibodies with the simplicity of a column-free magnetic system—for fast and easy isolation of highly purified cells that are ready for downstream applications. This versatile immunomagnetic cell separation technology enables positive selection, negative selection, or cell depletion.

EasySep™ can be used to isolate cells in as little as 8 minutes from a variety of species (e.g. human, mouse, non-human primate, rat, rabbit, cow and pig) and sample sources (e.g. splenocytes, lymph nodes, PBMCs, whole blood, leukopaks, cord blood, and bone marrow).*

How Does EasySep™ Cell Separation Work?

Cells are targeted for either removal (negative selection and depletion) or positive selection using antibody complexes directed to specific cell surface antigens. The antibody complexes link targeted cells to EasySep™ magnetic particles. Labeled cells are pulled to the sides of the tube when the sample is placed in an EasySep™ cell separation magnet, while untouched cells can be simply poured or pipetted off into a new tube.

Why Use EasySep™ to Isolate Cells?

  • Isolate cells in as little as 8 minutes with a simple pour.
  • Achieve up to 99% cell purities with high recoveries.
  • Obtain viable, functional cells without the need for columns and washes.
  • Isolate cells from virtually any sample source, including whole blood and Leukopaks.

Is EasySep™ a Well-Accepted Cell Isolation Method?

Since its launch in 2002, EasySep™ has been used in thousands of labs worldwide to quickly and easily isolate highly purified cells for a wide variety of applications. More immunologists are making the switch to EasySep™ and freeing up time to accomplish more in the lab. Switching your cell isolation technology to EasySep™ is easier than you think.



We use EasySep™ because of its ease of use and the high purity that we get from the preparation. I especially like the negative selection kits because it allows us to keep the cells that we collect as undisturbed as possible
