Overview

The EasySep™ Direct Human PBMC Isolation Kit is designed to isolate highly purified peripheral blood mononuclear cells (PBMCs) from fresh whole blood, buffy coat, bone marrow, cord blood, or leukapheresis products by negative selection. Red blood cells (RBCs), platelets and unwanted cells are targeted for removal with antibodies complexes and magnetic particles and separated using an EasySep™ magnet. Untouched PBMCs are simply collected into a new tube and are immediately available for downstream applications such as flow cytometry, culture or DNA/RNA extraction.
Advantages:
• 99.9% RBC depletion without the need for density gradient centrifugation, sedimentation or lysis
• Fast, easy-to-use and column-free
• Isolated cells are untouched

Data

Figure 1. Typical EasySep™ Direct Human PBMC Isolation Profile

In the above example, the mononuclear cell content of the whole blood start sample (lysed by ammonium chloride) and non-lysed final isolated fraction is 27.0% and 98.6% (not gated on CD45), respectively.

Figure 2. Representative Flow Cytometry Plots

Representative FSC vs. SSC flow cytometry plots of mononuclear cells isolated from whole blood samples using either density gradient centrifugation or EasySep™ Direct Human PBMC Isolation Kit.

Figure 3. Representative t-SNE plots of Isolated PBMCs

Representative t-SNE plots of PBMCs stained with 19 markers and analyzed with mass cytometry (CyTOF). Cells are clustered and colored based on the combination of markers they express. Both density gradient centrifugation and EasySep™ Direct Human PBMC Isolation Kit resulted in comparable cell populations with the exception of the contaminating granulocyte population (CD16+CD15+CD11b+CD66b+ CD45low).

Figure 4. EasySep™ Direct Human PBMC Isolation Kit Results in Fewer Contaminating Cells Compared to Density Gradient Centrifugation

Mononuclear cells were isolated from whole blood samples using either density gradient centrifugation or EasySep™ Direct Human PBMC Isolation Kit. Cells were counted and analyzed by flow cytometry. (A) Both density gradient centrifugation and EasySep™ Direct Human PBMC Isolation Kit resulted in an equivalent total number of nucleated cells recovered from 24-hour blood samples (mean ± SD; n=14). (B) Using EasySep™ Direct Human PBMC Isolation Kit to obtain mononuclear cells from 24-hour old blood samples resulted in lower numbers of residual platelets (CD41+), red blood cells (Glycophorin A+/CD45-), and granulocytes (CD66b+) compared to density gradient centrifugation (mean ± SD; n=15). (C) Cell isolation from 24-hour, 48-hour, 72-hour and 96-hour old blood samples using EasySep™ Direct Human PBMC Isolation Kit resulted in lower numbers of residual granulocytes compared to cell isolation using density gradient centrifugation (mean ± SD; n=3).

Figure 5. PBMCs Isolated with EasySep™ Direct Human PBMC Isolation Kit Proliferate and Maintain High RNA Integrity

Mononuclear cells were isolated from whole blood samples using either density gradient centrifugation or EasySep™ Direct Human PBMC Isolation Kit. (A) Isolated mononuclear cells were used for downstream RNA isolation. There was no significant difference in RNA integrity as measured with the Agilent RNA Bioanalyzer (mean ± SEM, n=3). (B) Isolated mononuclear cells were labeled with Proliferation Dye eFluor 450 and stimulated with ImmunoCult™ Human CD3/CD28 T Cell Activator and 0.5ng/ml IL-2. After 4 days in culture, cells were analyzed for proliferation by flow cytometry. Representative histogram showing dividing cells (eFluor 450low).
