anti-Rat IgG(HL)Fab-C-MMAF ADC (ADC-AA-047)

This ADC product is comprised of a Fab fragment of an anti-rat IgG(H+L) specific polyclonal antibody conjugated via a cleavable linker to MMAF. The antibody portion is a Fab fragment of a secondary antibody and the drug portion, MMAF, 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

  • Name
  • IgG(H+L)
  • Overview
  • IgG antibody subtype is the most abundant serum immunoglobulins of the immune system, which is a protein complex composed of four peptide chains—two identical heavy chains and two identical light chains arranged in a Y-shape typical of antibody monomers. IgG is secreted by B cells and is found in blood and extracellular fluids and provides protection from infections caused by bacteria, fungi and viruses.

 ADC Linker

  • Name
  • Cleavable linkers
  • Description
  • Cleavable linkers rely on the physiological stimuli, which mainly include chemically cleavable linkers and enzymatically cleavable linkers. Chemically cleavable linkers including acid-labile linkers and disulfide linkers. For acid-labile linkers, intracellular release of payloads relies on the different pH between endosomes/lysosomes and blood. The release of disulfide-linked drugs is controlled by the factors in intracellular environment. Enzymatically cleavable linkers, peptide linkers and β-glucuronide linkers, are sensitive to enzymes located in cytoplasm.

 ADC payload drug

  • Name
  • MMAF (Monomethyl auristatin F)
  • Description
  • Derived from Auristatin,are water-soluble dolastatin analogs of dolastatin 10. Dolastatin 10 belongs to dolastatin family and it can powerfully bind to tubulin, thus inhibiting polymerization mediated through the binding to the vinca alkaloid binding domain, and causes cell to accumulate in metaphase arrest.
