| abstract |
The present invention provides binding molecule or molecules that are able to multimerise CD45 to induce cell death of a cell expressing CD45 without also inducing significant cytokine release. For example, the invention provides antibodies against CD45, wherein the antibodies comprise at least two different paratopes each specific for a different epitope of CD45. The antibodies may be used to cross-link CD45 on the surface of cells. The antibodies may be used in a variety of therapeutic ways including to deplete cells, for example prior to cell transplantation. |
