Cell Isolation Technologies and Products Overview

Isolate cells in as little as 8 minutes with our widely-used cell separation systems. EasySep™, RosetteSep™, and SepMate™ are column-free cell separation technologies with fast and easy protocols. RoboSep™ instruments allow for fully automated cell isolation based on the EasySep™ column-free system. StemSep™ provides versatile cell isolation in a column-based format.

Immunomagnetic Cell Separation Technologies

EasySep™ Fast, Easy and Column-Free Cell Isolation

Cell isolation using an EasySep™ cell separation magnet

Typical Sample Source:

PBMCs*, Splenocytes, Leukopaks*, Whole Blood*


  • Isolate highly purified cells in as little as 8 minutes without columns
  • Cells are immediately ready for downstream analysis
  • Isolate cells from virtually any sample source or size
  • Fully automate using RoboSep™ cell separation technology

RoboSep™ Fully Automated Cell Isolation

Typical Sample Source:

PBMCs*, Splenocytes, Leukopaks*, Whole Blood*


  • Perform sequential or simultaneous cell separation from up to 16 samples
  • Minimize sample handling and eliminate cross-contamination
  • Use fast and easy pre-programmed protocols for routine cell isolation or custom protocols for special applications

StemSep™ Column-Based Cell Isolation

Typical Sample Source:

PBMCs*, Splenocytes, Bone Marrow


  • A wide selection of antibodies are available for custom separations
  • Cell isolation reagents can be used on other immunomagnetic column-based systems including manual and automated systems
  • Magnetic particles do not interfere with subsequent FACS analysis or other downstream applications

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.

Eric Song, MD/PhD Student

We like the reliability of the RoboSep™, the minimization/elimination of specimen handling by the tech during subset separation, and the low maintenance of the instrument. These factors are important to us with such a high throughput of samples processed.

Immunodensity Cell Separation Technologies

RosetteSep™ Cell Isolation Directly From Whole Blood

Typical Sample Source:


  • Isolate untouched cells directly from whole blood during standard density gradient centrifugation
  • No columns, magnets or special training required
  • Combine RosetteSep™ with SepMate™ to reduce centrifugation time and minimize variability

SepMate™ Hassle-Free PBMC Isolation

Typical Sample Source:


  • Isolate PBMCs directly from whole blood in just 15 minutes
  • Avoid the need for slow and laborious sample layering over density gradient medium
  • Simply pour off PBMCs after centrifugation
  • Minimize variability between separations
  • Combine with RosetteSep™ to isolate specific cell subsets

Density Gradient Media

Cell Source:

Peripheral whole blood, cord blood, bone marrow

I tested the SepMate™ tubes yesterday and they worked… fantastically! I ran in parallel the same sample with my standard protocol and the cell recovery was the same (in a quarter of the time, of course).
