Tefibazumab is a humanized IgG1κ monoclonal antibody that binds to the surface-expressed adhesion protein clumping factor A. Tefibazumab can be used for the research of serious Staphylococcus aureus infections.
Tefibazumab has a variable antigen binding region composed of human (>98%) and murine (<2%) amino acid sequences. Tefibazumab specifically recognizes and has a high affinity for ClfA expressed by S. aureus[2].
