EasySep™ Serology Whole Blood CD19 Positive Selection Kit
EasySep™ Serology Whole Blood CD19 Positive Selection Kit is designed to isolate highly purified CD19+ cells from fresh human whole blood by immunomagnetic positive selection. This kit targets human CD19+ cells for positive selection with an antibody recognizing the CD19 surface marker. Desired cells are labeled with antibodies and magnetic particles, and separated without columns using an EasySep™ magnet. Unwanted cells are simply poured off, while desired cells remain in the tube. Isolated cells are immediately available for downstream applications such as HLA serology, flow cytometry, or DNA/RNA extraction.
⦁ Up to 98% purity
⦁ No columns required
⦁ Compatible with HLA serological applications

Figure 1. EasySep™ Serology Whole Blood CD19 Positive Selection Kit
Starting with human whole blood, the CD19+ cell content of the isolated fraction typically ranges from 89.4 - 97.8% (note: as the CD19 antibody used for flow cytometry staining was fully blocked by the CD19 antibody used to isolate the cells, staining of B cells was assessed by labeling with anti-CD20 antibody; gated on CD45+). In the above example, the purities of the start and final isolated fractions are 7.3% and 96.2%, respectively (gated on CD45+).
NOTE: Red blood cells were removed from start sample by lysis prior to flow cytometry.
NOTE: The magnetic particles present on the surface of the isolated CD19+ cells will cause a large FSC/SSC shift when the samples are run on a flow cytometer. This will make it difficult to gate on a specific lymphocyte population based on FSC/SSC. Instead, we recommend first gating the cells on CD45 and examining the lymphocyte populations based on the CD45+ gate.
