Magnetic-activated cell sorting (MACS) MACS (Miltenyi Biotec, Bergisch Gladbach, Germany) is a cell separation technology based on the use of monoclonal antibody-conjugated magnetic beads. After incubating beads with a cell suspension, the cells are passed through a column within a magnetic field. Cells carrying the magnetic beads …

To address cell-type specific contributions, several techniques have been developed, including magnetic-activated cell sorting (MACS). Herein we describe the sequential isolation of CNS cell types via MACS. We find that MAC sorting of neural cells is relatively gentle, resulting in cells that retain processes.

In this contribution, we designed four types of immuno-magnetic nanoparticles for separation of different T cells (CD3 +, CD4 +, CD8 + and CD14 + T cells), and we established a new large-scale immuno-magnetic cell sorting procedure to achieve an enrichment of particular T cells using our designed auto-IMACS device. This device …
Cell isolation, also commonly referred to as cell separation or cell sorting, can be achieved using magnetic beads to target cells for selection or depletion by using ligands or antibodies directed against specific cell surface antigens. Labeled cells that are cross-linked to magnetic beads are immobilized using magnets or magnetic racks.
The remote and noninvasive control of living cells using magnetic fields (MFs) is at the top of the wish list of many researchers working in biology and medicine. ... The proposed magnetic-based cell division regulation strategy can improve the efficiency of microbial cell factories and medical applications of magnetosensitive bacteria. Full ...
The physical basis of the idea is that magnetic fields penetrate biological tissue practically without attenuation, but at specific sites in a cell, an MF is capable of triggering a wide …
Abstract. Magnetic cell sorting is an enabling tool for the isolation of specific cellular subpopulations for downstream applications and requires the cells to be labeled by a sufficient number of magnetic nanoparticles to leverage magnetophoresis for efficient separation. This requirement makes it challenging to target weakly expressed biomarkers.

Antibodies reacting to specific cell surface markers can be bound to magnetic beads and used to specifically capture cells exhibiting the marker. This approach allows the selective enrichment of specific cell subpopulations and as the methods are amenable to use in blood, tissue fluids and culture m …
The results showed that the assembled film of nanoparticles on the surface greatly enhanced the hydrophilicity and increased the elastic modulus of the scaffold, which subsequently improved the osteogenesis of the stem cells. Furthermore, the magnetic property of the IONPs proved to be the key factor in enhancing osteogenic differentiation ...
The m3D cell culture methods – levitation, bio, and ring formation (Fig. 1) – use the same methodology for magnetizing cells, which is based on the incubation of cells with magnetic nanoparticles that electrostatically and non-specifically binds to the cell membrane [14], [17].After magnetization, the cells are generally …
Magnetic cell separation is a low cost process that does not require specialized training or equipment, and eliminates the need for fluorescent cells. We propose that this technique will add significantly to our ability to efficiently study isolated/enriched cell populations in the CNS.
