ADCC, CDC, and ADCP Assay Services

We have the experience and expertise to provide complete ADCC/CDC/ADCP testing solutions.

ADCC, CDC, and ADCP are critical immune mechanisms that underlie the success of antibody-based therapies. Each of these mechanisms operates through distinct immune components but shares the goal of eliminating pathogenic or malignant cells. Creative Biolabs leverages its advanced technology platforms and extensive expertise to provide ADCC/CDC/ADCP levels detection services, helping you optimize antibody designs and give guidance on enhancing these effector functions for more effective therapies. Based on state-of-the-art laboratories, we can ensure the efficacy and potency of your therapeutic antibodies by implementing strict QC standards.

ADCC/CDC/ADCP in Antibody Development

Optimizing Antibody Therapeutic Efficacy

By measuring the levels of these activities during antibody discovery, researchers can assess and enhance the potential of therapeutic antibodies to elicit robust immune responses against target cells

Fine-tuning Antibody Design

Not all antibodies are designed to activate all three mechanisms (ADCC, CDC, ADCP). Some therapeutic strategies may prioritize one over the others, depending on the target disease and the desired immune response

Safety and Off-target Effects

Detecting these levels allows for a better understanding of the potential risks of non-specific immune activation.

Predicting Clinical Performance

The levels of ADCC, CDC, and ADCP detected during the discovery and development phases can serve as predictors of the clinical performance of the therapeutic antibody.

Regulatory and Quality Control

Accurate measurement of ADCC, CDC, and ADCP levels is important for meeting regulatory standards during the antibody development process.
