Apoptosis-inducing single-chain Fv

摘要

This invention relates to Novel single-chain Fvs capable of inducing apoptosis of nucleated blood cells having Integrin Associated Protein (IAP). The single-chain Fvs of the invention comprise an L chain comprising the L chain V region of the mouse monoclonal antibodies capable of inducing apoptosis of cells having human IAP, an H chain comprising the H chain V region of the mouse monoclonal antibodies capable of inducing apoptosis of cells having human IAP and a linker connecting them. The single-chain Fvs of the invention are useful as a therapeutic agent for blood dyscrasia such as leukemia.
