ADCC & CDC assays

Endpoint-Based, and Speedy

Dramatic improvement of ADCC [https://www.probiocdmo.com/add-adcc-cdc-assay.html] by using recombinant NK cells

Antibody therapy has been proven to be highly powerful for cancer treatment. Two important mechanisms used by antibody drugs to kill targeted tumor cells are Antibody-Dependent Cell-Mediated Cytotoxicity (ADCC), and Complement Dependent Cytotoxicity (CDC). ProBio is pleased to present to customers both a PBMC-based ADCC assay [https://www.probiocdmo.com/add-adcc-cdc-assay.html] and natural kill cell-based ADCC assay. The readout is endpoint-driven (target cell lysis). The CDC assay [https://www.probiocdmo.com/add-adcc-cdc-assay.html] uses normal human serum as the source of complement. By implementing strict QC standards, ProBio can provide the assurance of the efficacy and potency profiles of the therapeutic antibodies.
