| Description |
| CD45RO MicroBeads were developed for magnetic isolation of lymphocyte subsets. CD45RO is expressed on CD4+ and CD8+ T memory cells as well as on CD4+ effector T cells. CD45RO is also expressed on monocytes, macrophages, and granulocytes. The CD45RO antibody recognizes a 180 kDa isoform of the leukocyte common antigen (LCA). |
| Applications |
| CD45RO MicroBeads can be used for positive selection or depletion of CD45RO+ cells. For isolation of CD45RO+ T cell subsets, the CD45RO MicroBeads can be combined with CD4 and CD8 MACS® T Cell Isolation Kits1,2,7,8 or MultiSort Kits3,4. The CD45RO MicroBeads can also be used to isolate CD45RA+ cells from pre-sorted CD4+ or CD8+ T cells by depletion of CD45RO+ cells.5,7,8 Cells isolated with CD45RO MicroBeads can be used for various studies, such as cytokine expression6 or receptor signaling. |

| CD4+ cells were enriched from PBMCs by using the CD4 MultiSort Kit. After release of the MultiSort MicroBeads, the cells were magnetically labeled with CD45RO MicroBeads. CD4+CD45RO+ effector and memory T helper cells were isolated by positive selection. |
