Overview
This kit targets non-naïve B cells for removal with antibodies recognizing specific surface markers. 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 are immediately available for downstream applications such as flow cytometry, culture or DNA/RNA extraction.
Data Figures
Figure 1. Typical EasySep™ Direct Human Naïve B Cell Isolation Profile
Starting with human whole blood from normal healthy donors, the typical naïve B cell (CD19+CD27-) content of the non-lysed final isolated fraction is 91.8 ± 3.6% (gated on CD45) or 82.4 ± 12.6% (not gated on CD45). In the above example, the naïve B cell (CD19+CD27-) content of the lysed whole blood start sample and non-lysed final isolated fraction is 5.1% and 91.5% (gated on CD45), respectively, or 5.1% and 90.0% (not gated on CD45), respectively. The starting frequency of naïve B cells in the non-lysed whole blood start sample above is 0.009% (data not shown).

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.
