Overview

Easily and efficiently isolate highly purified human eosinophils (CD16-CD66b+CD45+) from fresh human peripheral blood polymorphonuclear cells (PMNCs) by immunomagnetic negative selection, with the EasySep™ Direct Human Eosinophil Isolation Kit. Widely used in published research for more than 20 years, EasySep™ combines the specificity of monoclonal antibodies with the simplicity of a column-free magnetic system.

In this EasySep™ negative selection procedure, unwanted cells are labeled with antibody complexes and magnetic particles. The magnetically labeled cells are then separated from the untouched desired eosinophils by using an EasySep™ magnet and simply pouring or pipetting the desired cells into a new tube. Following magnetic cell isolation, the desired eosinophils are ready for downstream applications such as flow cytometry, culture, or DNA/RNA extraction.

Data Figures

Figure 1. Typical EasySep™ Human Eosinophil Isolation Profile

Starting with whole blood prepared using RBC lysis or HetaSep™, the eosinophil content (CD16-CD66b+CD45+) of the isolated fraction is typically 96.5 ± 2.5% (mean ± SD) using the purple EasySep™ Magnet. In the above examples, the purities of the start and final isolated fractions prepared using RBC lysis are 1.8% and 97.8% (gated on CD45+), respectively, and when prepared using HetaSep™, the purities are 2.4% and 96.8% (gated on CD45+), respectively.
