Whether you require highly purified populations separated by positive selection or untouched cells from whole blood, MACS Technology has a solution for you.
For the isolation of ROR1+ B cells, we have developed the Anti-ROR1 MicroBead Kit, human. Using this kit, ROR1+ cells are indirectly magnetically labeled with an Anti-ROR1-PE antibody and Anti-PE MicroBeads. The isolated ROR1+ B cells are then ready for any downstream analysis. ROR1+ cells can be enriched to high purities and numbers suitable for further research processing – even from samples with very low ROR1+ B cell frequencies, e.g., in minimal residual disease (MRD).
MACSxpress® Technology is designed to isolate viable and functional B cells fast and conveniently from blood and blood products. This cell isolation technology is based on micro-sized MACSxpress Beads, which allow the removal of non-target cells by immunomagnetic depletion using the MACSxpress Separator, a powerful permanent magnet. All without the need of density gradient centrifugation or red blood cell lysis.
Untouched B-CLL cells were isolated from 30 mL of human EDTA-anticoagulated whole blood using the MACSxpress® Whole Blood B-CLL Cell Isolation Kit, a MACSmix™ Tube Rotator, and a MACSxpress Separator. The isolated cells were fluorescently stained with CD19-PE and CD45-VioBlue® and analyzed by flow cytometry using the MACSQuant® Analyzer 10. Cell debris, non-leukocytes, and dead cells were excluded from the analysis based on CD45 expression, scatter signals, and propidium iodide fluorescence. This way a high cell purity can reached in a very short time.
As the final step in this workflow, flow analysis plays an important part. The following flow reagents can help you make sure that the data you generate on your flow cytometer are reliable and consistent:
Reproducibility is a key factor in flow cytometry experiments. It can be influenced by biological material, reagents and instrumentation, as well as analysis of acquired data, whereby the operator leads to variable results.
Our MACSQuantify™ Express Modes are software add-ons for our MACSQuant® Analyzer Flow Cytometers. They are algorithm-based gating tools that allow for an unbiased and user-independent analysis, resulting in improved reproducibility of flow cytometry data and statistics. Based on real data, analysis and acquisition, scripts facilitate automated, application-specific gating on the actual population distribution.
