Product Specification
| Format | Dextran-coated iron tetroxide magnetic nanoparticles conjugated with an anti-human CD15 monoclonal antibody. |
| Capacity |
1 mL magnetic beads: suitable for a total cell count of 5×108and can perform up to 50 sorting runs. 2 mL magnetic beads: suitable for a total cell count of 1×109and can perform up to 100 sorting runs. |
| Principle of Separation | CD15⁺ cells are magnetically labeled using CD15 Nanobeads. The cell suspension is then loaded into a separation column placed within the sorter's magnetic field. The magnetically labeled CD15⁺ cells remain retained in the column, while the unlabeled cells elute; this fraction constitutes the negative fraction after removal of CD15⁺ cells. After removing the separation column from the magnetic field, the magnetically captured CD15⁺ cells can be eluted, yielding the positive sorted fraction. |
| Applications in cell sorting | Eosinophils and neutrophils can be isolated from or depleted from tissue samples, such as human peripheral blood or ovarian cancer tissues. |
| Reactivity | Human |
| Magnetic Bead Size | 20 nm |
| Separation Method | Column-Based |
| Selection Strategy | Positive Selection |
| Stability & Storage | Store protected from light at 2–8°C; do not freeze. |
Background
CD15 Nanobeads, human are designed to positively select or deplete CD15-positive cells from human peripheral blood or tissue single-cell suspensions. The CD15 antigen is expressed on neutrophils, eosinophils, and myeloid lineage monoblast progenitor cells, but it is not expressed on basophils or lymphocytes. Furthermore, this antigen is also expressed in Hodgkin/Reed-Sternberg cells.
Protocol
Note: This kit does not include the sorting buffer; it must be provided separately. The corresponding Stater product number is S0D3018.
