MC-VC-PAB-O-Gemcitabine is a linker-antibiotic intermediate, which is part of the antibody-antibiotic conjugate (AAC) molecule. MC-VC-PAB-O-Gemcitabine is conjugated with the linker and the antibiotic Gemcitabine. MC-VC-PAB-O-Gemcitabine can be used to study the immunotherapy of bacterial infections and the development of new antibacterial drugs[1].
