Overview
Data Figures
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.
