MACS Technology Gold standard in cell separation MACS Technology MACS Technology has become the standard method for cell separation. Numerous publications have proven its versatility for multiple applications: cell separations with consistent high-quality results from lab bench to clinical applications, from small to large scale, from frequently occurring cells to rare cells and sophisticated subsets. Miltenyi Biotec provides researchers worldwide with the tools for high-quality separations. MACS Cell Separation is based on the use of MACS MicroBeads, MACS Columns, and MACS Separators. Cells can easily be purified or depleted in less than 30 minutes. Magnetic labeling Gentle to cells; minimal influence on downstream experiments The principle MACS Technology is based on MACS MicroBeads, MACS Separators, and MACS Columns. MACS MicroBeads are superparamagnetic particles of approximately 50 nanometers in diameter. They are composed of a biodegradable matrix, and it is therefore not necessary to remove them from cells after the separation process. Usually, MACS MicroBeads do not alter structure, function, or activity status of labeled cells and are not known to interfere with subsequent experiments. Magnetic separation MACS Column Technology provides a high-gradient magnetic field. Gentle to cells Thorough rinsing procedure High recovery Untouched isolation by depletion of specific cells N S MACS Technology takes place within MACS Columns. When a MACS Column is placed in a MACS Separator, a strong permanent magnet, a high-gradient magnetic field is induced on the column matrix strong enough to retain cells labeled with minimal amounts of MACS MicroBeads. Unlabeled cells pass through and can be collected; labeled cells are released after removal of the column from the magnet. Thus, with MACS Technology both labeled and unlabeled cell fractions can easily be isolated with high purity. The entire procedure of positive selection or depletion takes less than 30 minutes, and cells can immediately be used for further experiments. Elution of the labeled cell fraction Optimal results even for rare cells by using positive selection CD133/2-PE Anti-Biotin-PE CD34-FITC Electron micrographs on this page with courtesy of Prof. Peter Groscurth, Institute of Anatomy, University of Zürich, Switzerland.
MACS Magnetic Labeling Direct magnetic cell labeling Indirect magnetic cell labeling Direct labeling is the fastest way of magnetic labeling. It requires only one labeling step since the specific antibody is directly coupled to the magnetic particle. Direct labeling reduces the number of washing steps and, therefore, avoids unnecessary cell loss. Miltenyi Biotec provides highly specific monoclonal antibodies for low background and optimal separation, targeted against surface markers of cells from various species such as human, mouse, rat, and non-human primates. Fluorochrome-conjugated MACS Antibodies can be added for the purpose of analyzing magnetically separated cell fractions by flow cytometry or fluorescence microscopy. Indirect labeling is performed if no direct MicroBeads for the cell type of interest are available. Almost any monoclonal or polyclonal antibody targeting any cell type from any species can be used for indirect labeling. Cells are labeled with a primary antibody that is unconjugated, biotinylated, or fluorochrome-conjugated. In a second step, magnetic labeling is performed by using Anti-Immunoglobulin, Anti-Biotin, Streptavidin, or Anti-Fluorochrome MicroBeads, respectively. A cocktail of antibodies can also be used to isolate or deplete a number of cell types concurrently. Since indirect labeling amplifies the magnetic label, it may be the method of choice for magnetic separation according to dimly expressed antigens.

MACS Separation Strategies Positive selection strategy Untouched isolation Positive selection means that the desired target cells are magnetically labeled and isolated as the magnetically retained cell fraction. A positive selection strategy should be considered for: excellent purity, especially for rare cell enrichment, excellent recovery, and fast results. Positive selection is the most direct and specific way to isolate the target cells from a heterogenous cell suspension. Binding of antibodies (which are part of the MicroBeads) to the cell surface does not affect viability or function of the cells. Both fractions, labeled and unlabeled, can be recovered and used. Due to their composition of iron oxide and polysaccharide, MicroBeads are biodegradable and typically disappear after a few days in culture. Untouched isolation is performed by depletion of undesired cells. Non-target cells are magnetically labeled and eliminated from the cell mixture. The non-magnetic, untouched cell fraction contains the target cells. Untouched isolation should be considered: for removal of unwanted cells, if no specific antibody is available for target cells, if binding of the antibody to the target cells is not desired, or for subsequent isolation of a cell subset by means of positive selection. For many different cell types Miltenyi Biotec offers optimized MACS Cell Isolation Kits containing pre-titrated cocktails of antibodies directed against non-target cells. Magnetic labeling Cells of interest are magnetically labeled with MACS MicroBeads. Magnetic labeling Non-target cells are magnetically labeled with a biotinylated antibody cocktail and Anti-Biotin MicroBeads. Magnetic separation Cells are separated in a MACS Column placed in a MACS Separator. The flow-through fraction can be collected as negative fraction depleted of the labeled cells. Magnetic separation Undesired cells are retained in a MACS Column placed in a MACS Separator. The target cells pass through the column and are collected as the enriched, unlabeled cell fraction, depleted of non-target cells. Elution of the labeled cell fraction The column is removed from the separator. The retained cells are eluted as the enriched, positively selected cell fraction.
MACS Separation Strategies Sequential sorting (1): Depletion followed by positive selection Cell subsets can be isolated by first depleting the non-target cells and then positively selecting the cell subsets of interest. This strategy is useful if undesired cells in the cell suspension express the same antigen which is used for positive selection of the target cells. For isolation of extremely rare cells, it also can be useful first to deplete non-target cells from the suspension. Positive selection can then be carried out with the pre-enriched fraction to obtain very pure cells. 1st magnetic labeling Non-target cells are magnetically labeled with a biotinylated antibody cocktail and Anti-Biotin MicroBeads. Sequential sorting (2): MultiSort strategy With MACS MultiSort Kits high numbers of cells, characterized by multiple cell surface markers, can be sorted easily. Even rare cells can be enriched very efficiently. Multi-parameter sorting with MACS MultiSort Kits allows sequential positive selections of cells. The target cells are first labeled with MACS MultiSort MicroBeads and positively selected for the first parameter. Then the cells are incubated with the MultiSort Release Reagent which enzymatically removes the MicroBeads from the antibodies. In the next step, the target cells are magnetically labeled with MACS MicroBeads directed against a subset marker to be positively selected a second time. 1st magnetic separation Undesired cells are retained in a MACS Column placed in a MACS Separator while the unlabeled cells pass through. 1st magnetic labeling Cells of interest are magnetically labeled with MultiSort MicroBeads. 1st magnetic separation Target cells are magnetically isolated by positive selection. 2nd magnetic labeling Target cells are magnetically labeled with MicroBeads according to a subset marker. Release of magnetic particles MultiSort MicroBeads are enzymatically released. 2nd magnetic separation Target cells are retained in the column while unlabeled cells pass through. After the column is removed from the separator, the target cells are eluted as the enriched, positively selected cell fraction. 2nd magnetic labeling Cell subset of interest is labeled with MACS MicroBeads according to a second marker. 2nd magnetic separation Target cells are positively selected a second time.
