Fab Anti-Human IgG Fc-DX9851 Antibody with Cleavable Linker

Catalog Number: AH-207-DX

Fab-αHFc-CL-DX8951 is a Fab fragment of anti-human IgG Fc specific antibody conjugated to exatecan mesylate (DX8951) with a cleavable linker. The antibody portion is a polyclonal antibody Fab fragment specific to the Fc region of human IgGs. Exatecan mesylate (DX8951) is a topoisomerase I inhibitor. The cleavable linker (GGFG) connecting DX8951 to the antibody is stable in extracellular fluid, but is cleaved by in endosome once the conjugate has entered a cell via endocytosis.The mono-valence nature of Fab 2°ADC may have some advantage in certain applications than the full length IgG 2°ADC.
