| Description |
| CD56 MicroBeads were developed for the positive selection or depletion of natural killer (NK) cells from human blood or single-cell suspensions from tissues. The CD56 antigen is expressed by most NK cells and a minor T cell subset (CD3+CD56+ NKT cells). Upon activation of NK cells, the surface expression of CD56 is increased. |
| Applications |
| CD56+ cells are used in studies on NK cell development, proliferation, or cytotoxic activity as well as in analysis of signal transduction and related molecular processes. For information on clinical products click here. CD56 could also be used for the enrichment of embryonic stem cell–derived cardiomyocytes cells after in vitro differentiation1 as well as the direct selection stem and progenitor cells from muscle tissue2,3. |
