Chimeric antibody for detection and therapy of infectious and inflammatory lesions

摘要

A chimeric antibody-agent conjugate for targeting foci of leukocyte accretion comprises a recombinant chimera having an antigen-binding hypervariable region which binds specifically to granulocytes, and a constant region of a human immunoglobulin having an Fc portion with high affinity for receptors on human mononuclear lymphoid cells, said chimera being conjugated to at least one diagnostic agent or therapeutic agent. A method for targeting an imaging or therapy agent to an inflammatory or infectious lesion comprises injecting a mammal parenterally with an effective amount for targeting of the above chimeric anti-leukocyte conjugate.
