This cell isolation kit targets non-B cells for removal based on specific surface antigens. Unwanted cells are labeled with antibodies and EasySep™ Direct RapidSpheres™, and separated using an EasySep™ magnet. Desired cells are simply collected into a new tube and can immediately be used in downstream applications such as nucleic acid extraction, flow cytometry or culture.
• Fast, easy-to-use and column-free
• Isolated cells are untouched

Frequently Asked Questions
Can EasySep™ be used for either positive or negative selection?
How does the separation work?
Which columns do I use?
How can I analyze the purity of my enriched sample?
Can EasySep™ separations be automated?
Can EasySep™ be used to isolate rare cells?
Are the EasySep™ magnetic particles FACS-compatible?
Can the EasySep™ magnetic particles be removed after enrichment?
Can I alter the separation time in the magnet?
For positive selection, can I perform more than 3 separations to increase purity?
How does the binding of the EasySep™ magnetic particle affect the cells? is the function of positively selected cells altered by the bound 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.

Data and Publications
Figure 1. Typical EasySep™ Direct Human B-CLL Cell Isolation Profile
Starting with human whole blood from normal healthy donors, the typical B cell (CD3-CD19+) content of the non-lysed final isolated fraction is 87.0 ± 7.6% (gated on CD45) or 84.1 ± 11.7% (not gated on CD45). In the example above, the B cell (CD3-CD19+) content of the lysed whole blood start and non-lysed final isolated fraction is 4.3% and 88.0% (gated on CD45), respectively, or 4.3% and 86.2% (not gated on CD45), respectively. The starting frequency of B cells in the non-lysed whole blood start sample above is 0.004% (data not shown). The purity of isolated cells is typically higher when processing samples that have an elevated starting frequency of B cells (e.g. CLL samples).
