Overview
This product labels RBCs, platelets and unwanted cells with antibody complexes and magnetic particles. The magnetically labeled RBCs, platelets and non-target cells are separated from the untouched CD4+ T cells in an EasySep™ magnet and poured or pipetted into a new tube.
Isolated cells are available for use in downstream uses such as flow cytometry, functional assays or culture.
Data Figures

Figure 1. Typical EasySep™ Direct Human CD4+ T Cell Isolation Profile
Starting with human whole blood from normal healthy donors, the typical CD4+ T cell (CD3+CD4+) content of the non-lysed final isolated fraction is 93.6 ± 2.5% (gated on CD45) or 93.1 ± 2.5% (not gated on CD45). In the example above, the CD4+ T cell (CD3+CD4+) content of the lysed whole blood start sample and non-lysed final isolated fraction is 16.5% and 95.8% (gated on CD45), respectively, or 16.3% and 95.1% (not gated on CD45), respectively. The starting frequency of CD4+ T cells in the non-lysed whole blood start sample is 0.016% (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.
