HighlightsAntibody sialylation, the terminal modification of Fc glycans with sialic acid, is a critical quality attribute that directly governs therapeutic antibody efficacy, stability, and immunomodulatory functions, necessitating precise characterization. Creative Biolabs' Therapeutic Antibody Sialic Acid Analysis Service provides in-depth profiling of sialic acid content, linkage specificity, and site occupancy. We employ a multi-platform strategy, integrating advanced techniques like MS, lectin-based arrays, and linkage-specific mass spectrometry. Our service delivers high-resolution, reproducible data and expert interpretation, empowering clients to optimize antibody therapeutics, ensure lot-to-lot consistency, and accelerate product development with confidence.
Antibody sialylation is the attachment of sialic acids to antibody Fc glycans. It critically modulates effector functions like anti-inflammatory activity and ADCC. Analysis is vital for therapeutic efficacy, biomarker discovery, and bioprocess control. Key methods include LC-MS/MS for quantification, lectin assays for linkage specificity, chemical tagging via periodate oxidation, and metabolic labeling. Advanced techniques enable precise structural characterization, supporting glycoimmunology research and tailored biotherapeutic development.

Creative Biolabs' Therapeutic Antibody Sialic Acid Analysis Service delivers definitive characterization of this critical terminal glycan. Precise quantification of sialic acid species, such as Neu5Ac vs. Neu5Gc, is essential for predicting therapeutic safety, stability, and efficacy. We provide accurate, regulatory-ready data to support your product development from candidate screening through regulatory submission, ensuring quality and de-risking your program.
We provide an integrated analytical platform for precise sialylation characterization of therapeutic antibodies, encompassing quantitative assessment, structural mapping, and macro-heterogeneity evaluation.
Therapeutic Antibody Sialic Acid Analysis serves as a cornerstone of our comprehensive Therapeutic Antibody Glycan Characterization service, providing precise quantification of sialylation levels—a critical parameter for evaluating therapeutic efficacy and safety. To deliver a holistic glycosylation profile, we offer a suite of complementary, in-depth analytical modules, including ADC Glycoform Analysis for antibody-drug conjugates, Therapeutic Antibody Intact Released Glycan Analysis for global glycan profiling, and Therapeutic Antibody N-Glycan Analysis for detailed structural characterization of N-linked glycans. This integrated portfolio ensures we can address your diverse glycosylation analysis needs across all stages of therapeutic development.
Required Starting Materials: To begin the analysis, please supply 50–100 µg of your purified antibody (either in solution or lyophilized) along with information regarding its formulation buffer.
Key Steps
Final Deliverables: Upon completion, you will be provided with a detailed analytical report containing all raw chromatographic data, absolute molar quantification (expressed as nmol/mg), and a formal Certificate of Analysis (CoA).
Creative Biolabs excels in antibody sialic acid characterization by leveraging a sophisticated, multi-tiered analytical strategy supported by state-of-the-art instrumentation. This ensures both high-fidelity data and exceptional chromatographic resolution. Our distinctive workflow enables swift preliminary screening for efficient candidate selection, coupled with exhaustive profiling for definitive lead analysis. Partner with us for authoritative insights that streamline development and mitigate project risks.
"The analysis service provided by Creative Biolabs is essential for profiling our IgG1 candidates. The DMB-labeling methodology delivered the exceptional sensitivity required to accurately quantify the typically low and challenging sialylation levels on Fc glycans." Dr. A***n L.
"Their 96-well platform revolutionized our screening efficiency. By eliminating the time-consuming dry-down step, the workflow minimized handling errors and enabled us to profile over 50 lead candidates with unprecedented speed." Sarah K***s.
"This platform provided critical clarity for our intact protein analysis. We achieved clear resolution of G0, G1, and G2 glycoforms, yielding precise data that was foundational for our subsequent pharmacokinetic/pharmacodynamic (PK/PD) modeling." Michael R***o.
