Methods and compositions for binding to the membrane-bound form of IL1 RAP. In some embodiments, the invention provides an isolated antibody that binds the membrane bound fom1 of human IL1 RAP. In some cases, the isolated antibody that binds the membrane-bound form of human IL1 RAP docs not bind, or does not substantially bind, the soluble form of human IL1 RAP. For example, in some cases, the isolated antibody that binds the membrane-bound form of human IL1RAP does not bind, or does not substantially bind the soluble form of human IL1RAP that is found in normal human serum. In some cases, the soluble form of human IL1 RAP comprises the sequence GNRCGQ. |
