Humanization of a mouse monoclonal antibody directed against a cell surface-exposed epitope of membrane-associated heat shock protein 70 (Hsp70).

The translocation of heat shock protein 70 (mHsp70) into the plasma membrane has been found to be associated with various cancers including breast cancer, head-and-neck cancer, and acute myeloid leukemia. Parts of the C-terminal substrate-binding domain (SBD) of mHsp70 are accessible to binding by monoclonal antibodies (mAb). One of these mAbs, cmHsp70.
