NK cells play a primary role as a first line of defence by mediating anti-viral immune responses. Isolation and expansion of NK cells from virus-infected individuals are valuable steps for studying their immune responses i.e. by flow cytometry.
The MACSxpress® Whole Blood NK Cell Isolation Kit, human enables fast isolation of NK cells with high purity from as little as 2 mL of whole blood. MACSxpress Technology is designed to minimize hands-on time – density-gradient centrifugation and erythrocyte lysis are not required.
Untouched NK cells from whole blood. The MACSxpress Whole Blood NK Cell Isolation Kit, human, was used to separate NK cells from 30 mL of human EDTA-anticoagulated whole blood. The isolated cells were fluorescently stained with CD45-VioBlue, CD3-FITC, and CD56-PE, and analyzed by flow cytometry using the MACSQuant® Analyzer. Cell debris, non-leukocytes, and dead cells were excluded from the analysis based on CD45 expression, scatter signals, and propidium iodide fluorescence.
Comprehensive assays require a large quantity of NK cells. NK MACS® Medium has been optimized specifically for NK cell cultivation and expansion. Cells expanded in this medium remain fully functional and are ready to use for any downstream assay.
NK MACS Medium, research grade is a cell culture medium developed specifically for NK cells. It has been used in a variety of applications and, in combination with MACS Cytokines, is an ideal starting point for reliable cultivation conditions.
