Anwendungsinformationen

Protokoll: Leukocytes are labeled with BD Imag™ anti-mouse Ly-6G and Ly-6C (Gr-1) Particles - DM according to the following protocol. This labelled cell suspension is then placed within the magnetic field of the BD Imagnet™ Cell Separation Magnet (Cat. No. 552311). Labelled cells migrate toward the magnet (positive fraction), leaving the unlabelled cells in suspension so they can be drawn off (negative fraction). The tube is then removed from the magnetic field for resuspension of the positive fraction. The separation is repeated twice to increase the purity of the positive fraction. The magnetic separation steps are diagrammed in the Separation Flow Chart. After the positive fraction is washed, the small size of the magnetic particles allows the positive fraction to be further evaluated in downstream applications such as flow cytometry.

MAGNETIC LABELING PROTOCOL
1. Prepare a single-cell suspension from the lymphoid tissue of interest according to standard laboratory procedures. Remove clumps of cells and/or debris by passing the suspension through a 70-µm nylon cell strainer.
2. Dilute BD™ Imag Buffer (10X) (Cat. No. 552362) 1:10 with sterile distilled water to prepare 1X BD Imag buffer by supplementing Phosphate Buffered Saline with 0.5% BSA, 2 mM EDTA, and 0.09% sodium azide). Place on ice. Although our experience indicates that use of Mouse BD Fc Block™ purified anti-mouse CD16/CD32 mAb 2.4G2 (Cat. No. 553141/553142) is not required for optimal cell separation, some laboratories may want to use it in their studies. If adding Mouse BD Fc Block, proceed to Step 3. If not adding Mouse BD Fc Block, proceed to Step 4.
3. Add Mouse BD Fc Block at 0.25 µg/10^6 cells, and incubate on ice for 15 minutes.
4. Wash cells with at least an equal volume of 1X BD Imag buffer, and then resuspend the pellet in 90 µl 1X BD IMag buffer for every 10^7 total cells. If using fewer than 10^7 total cells, resuspend in a 90 µl volume.
5. Vortex the BD IMag™ anti-mouse Ly-6G and Ly-6C (Gr-1) Particles - MSC thoroughly, and add 10 µl of particles for every 10^7 total cells.
6. MIX THOROUGHLY. Refrigerate at 6°C - 12°C for 15 minutes.
7. Wash labeled cells with 20 times the labeling volume of 1X BD IMag buffer, remove supernatant completely, and resuspend the cells at a concentration that is appropriate for the magnetic separation column to be used.
8. Separate the cells according to the manufacturer's recommended procedure for the magnetic separation column being used.
The concentration of BD™ IMag anti-mouse Ly-6G and Ly-6C (Gr-1) Particles - MSC suggested in the protocol has been optimized for the purification of Gr-1 positive leukocytes from mouse bone marrow. When labeling target cell populations present at lower frequencies, fewer BD IMag particles can be used. Conversely, when labeling target cell populations that are present at higher frequencies, more particles should be used. To determine the optimal concentration of the BD™ IMag anti-mouse Ly-6G and Ly-6C (Gr-1) Particles - MSC for a particular application, a titration in two-fold increments is recommended.
Note: Avoid nonspecific labeling by working quickly and adhering to recommended incubation times.

Hintergrund: BD IMag™ anti-mouse Ly-6G and Ly-6C (gr-1) Particles - DM are magnetic nanoparticles that have monoclonal antibodies conjugated to their surfaces. These particles are optimized for the positive selection or depletion of Gr-1-bearing leukocytes using the BD Imagnet™ Cell Separation Magnet. In the periphery, RB6-8C5 antibody recognizes primarily granulocytes (neutrophils and eosinophils) and monocytes. In the bone marrow, it recognizes myeloid cells but not erythroid or lymphoid cells. Positive selection and depletion of mouse Ly-6g and Ly-6C (Gr-1) positive lymphocytes. Bone marrow cells were labeled with BD IMag™ anti-mouse Ly-6G and Ly-6C (Gr-1) Particles - DM as described in the protocol. After labeling, the cells were separated using the BD IMagnet™ Cell Separation Magnet, and the negative (Ly-6G and Ly-6g-) and positive (Ly-6G and Ly-6C+) fractions were collected. Please refer to the Separation Flow Chart to identify the separated cell populations represented in this figure. Foe flow cytometric analysis, fresh bone marrow (top panel), the negative fraction (middle panel), and the positive fraction (right panel) were stained with FITC-conjugated anti-mouse CD11b mAb M1/70 (Cat. No. 553310) and PE-conjugated anti-mouse Ly-6G and Ly-6C (Gr-1) mAb RB6-8C5 (Cat. No. 553128). The percent Gr-1+ cells in each sample is given. The expected cell recovery ranges from 60% to 80%.
