This ADC product is comprised of an anti-human IgG Fab specific polyclonal antibody conjugated via a noncleavable linker to DM1. The antibody portion is a secondary antibody and the drug portion, DM1, is a cytotoxic small molecule which binds to tubulins, interrupts microtubule dynamics, and induces cell death. This product displays no obvious toxicity without a primary antibody and can be a quite efficient and economical alternative to pre-screening human monoclonal antibodies as ADC candidates.
ADC Target
- Overview
- The fragment antigen-binding (Fab) fragment is a region on an antibody that binds to antigens. It is composed of one constant and one variable domain of each of the heavy and the light chain. The variable domain contains the paratope (the antigen-binding site), comprising a set of complementarity determining regions, at the amino terminal end of the monomer. Each arm of the Y thus binds an epitope on the antigen

ADC Linker
- Name
- Noncleavable linkers
- Description
- Noncleavable linkers, is considered noncleavable-meaning linker cleavage, and payload release does not depend on the differential properties between the plasma and some cytoplasmic compartments. Instead, the release of the cytotoxic drug is postulated to occur after internalization of the ADC via antigen-mediated endocytosis and delivery to lysosomal compartment, where the antibody is degraded to the level of amino acids through intracellular proteolytic degradation.
ADC payload drug
- Name
- DM1 (N2’-Deacetyl-N2’-(3-mercapto-1-oxopropyl)maytansine)
- Description
- Derived from Maytansinoid,a group of cytotoxins structurally similar to rifamycin, geldanamycin, and ansatrienin. The eponymous natural cytotoxic agent maytansine is a 19-member lactam (ansa
macrolide) structure originally isolated from the Ethiopian shrub Maytenus ovatus. Maytansinoids can bind to tubulin at or near the vinblastine-binding site, which interfere the formation of microtubules and depolymerize already formed microtubules, inducing mitotic arrest in the intoxicated cells.
