Antibody Functionality & Potency Evaluation Services
Creative Biolabs provides antibody functionality & potency evaluation services that utilize advanced functional and potency bioassays together with comprehensive characterization platforms to confirm the mechanism of action and ensure the safety and efficacy of biotherapeutic candidates. These services are designed to streamline antibody development and accelerate the delivery of high-quality therapeutic solutions.
Introduction
Monoclonal antibodies (mAbs) represent complex biotherapeutics where therapeutic efficacy relies on specific molecular interactions and potent biological activities. Key functional properties—such as extended serum half-life, antibody-dependent cell-mediated cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and precise binding affinity—are essential for clinical success. Thus, thorough analytical and functional characterization is vital in biologics development, guaranteeing product quality, batch consistency, and regulatory compliance across the entire lifecycle.
Service
Creative Biolabs delivers precise functional data and clear potency metrics essential for advancing your antibody therapeutics. We provide robust solutions for de-risking your development pipeline by confirming target engagement, elucidating mechanisms of action, and quantifying biological activity. Our services enable informed decision-making, from lead candidate selection to IND submission, by addressing key questions about your antibody's performance and potential unexpected effects. You can expect regulatory-compliant reports and expert interpretation to guide your project efficiently.
Creative Biolabs provides customized solutions specifically designed to meet your antibody development requirements.
- Comprehensive Functional Characterization: Assess key antibody mechanisms—including antigen binding (Fab) and Fc-mediated functions like ADCC, CDC, and receptor interactions—via robust in vitro assays.

Featured Services
ADCC Evaluation
We offer fully validated ADCC assays, utilizing platforms such as PBMC- or NK-cell-mediated killing to measure the cytotoxic effect of antibody-bound targets. Assays can include optimized effector-target conditions for accurate characterization.
CDC Evaluation
Our CDC assays assess the ability of your antibody to activate the complement cascade via C1q binding and initiate membrane attack complex formation. Assay formats include radioisotope release and flow cytometry-based detection, designed for dose-response and mechanism interrogation.
Neutralization Evaluation
Our neutralization assays provide sensitive, high-throughput platforms-including ELISA-based micro-neutralization, pseudovirus systems, and microfluidic droplet screening assess the potency of antibodies against pathogens, toxins, or ligand-receptor interactions.
Phagocytosis Evaluation
Also referred to as ADCP, our phagocytosis evaluation services complement ADCC and CDC assays, offering a broader perspective on Fc-mediated immune functions relevant to therapeutic antibody efficacy.
Antibody Functional Analysis
Target binding assays (flow cytometry, SPR/BLI) to evaluate antigen affinity and simultaneous dual-target binding for bispecifics. Reporter gene, proliferation, apoptosis, receptor activation/inhibition, internalization, and other tailored assays for mechanistic insights.
In Vivo Efficacy Analysis
We support in vivo studies with PK/PD bioanalytical assays, enabling you to assess antibody concentration, distribution, and functional performance over time in relevant models. Whether through cytokine profiling or functional endpoints, these studies underscore therapeutic relevance.
