Antibody Drug Conjugate – Molecule Synthesis

We have prepared >20,000 ADC molecules. In addition, we have scaled up hundreds of grams of ADC candidate compounds for further studies.

  • Considerable experience in the synthesis of novel payloads and their analogs.
  • Large collection of frequently used linkers in house, including PEG linkers, alkyl linkers, click chemistry linkers, and rigid linkers.
  • We have also assembled a collection of over 30 series of attachment sites.

What is an antibody drug conjugate

WuXi Biology provides ADC-based in vitro assays and in vivo models:

  • Target validation and antibody binding assay
  • Antibody internalization assay
  • Cell viability assay
  • Bystander killing assay
  • ADCC and ADCP assay
  • CDX and PDX models covering multiple targets (HER2, CLDN18.2, CD30, CD33, BCMA, Trop-2, CD79b, Nectin-4)

Target validation and antibody binding assay

ADC - Antibody Binding Assay

Cell viability assay_SK-BR-3

ADC - Cell Viability Assay Cytotoxicity

Antibody internalization assay

ADC - Antibody Internalization Assay

Bystander Killing Assay

Bystander killing occurs when the drug from an ADC is released either from the target cell following
internalization and degradation of the ADC or release of the drug within the extracellular space.

ADC - Bystander effect, cytotoxicity cell viability assay

Antibody-dependent cell-mediated phagocytosis (ADCP)

  • Effector: Macrophage isolated from PBMC of healthy donor
  • Target: SK-BR-3 cell line, labeled with 50 nM CellTrace Violet
  • E:T= 8:1
