Defining the glycan profile of therapeutic antibodies, a vital determinant of their function and stability, poses significant challenges due to the limitations of traditional, cumbersome analytical techniques. Creative Biolabs' Therapeutic Antibody N-Glycan Analysis Service directly addresses this need. Utilizing a state-of-the-art high-resolution mass spectrometry platform, we perform in-depth characterization of glycosylation patterns. This enables precise, semi-quantitative assessment and integrated multi-attribute evaluation, delivering the critical data required to advance your biotherapeutic development, ensure stringent quality oversight, and facilitate robust biosimilarity assessments.
Established techniques for N-glycan profiling, such as fluorophore-tagging of enzymatically liberated glycans, often involve protracted procedures and face analytical constraints, including potential structural loss or incomplete resolution. Here, we present a validated subunit-level strategy employing hydrophilic interaction liquid chromatography coupled with high-resolution mass spectrometry. This methodology facilitates the precise, high-fidelity, and semi-quantitative analysis of glycoforms through the characterization of ~25 kDa proteolytic fragments. As an efficient and multi-attribute platform, it serves as a viable successor to conventional workflows, delivering critical data to support both quality assurance and the informed development of antibody therapeutics.

Our Therapeutic Antibody N-Glycan Analysis Service sets the standard by integrating bioprocess innovations with exclusive Upper-Hinge Middle-Up (UHMU) technology to reveal critical heavy-chain glycan pairing. We deliver rapid, high-fidelity data, identify trace immunogenic epitopes, and achieve this with minimal sample consumption, providing unmatched depth and efficiency for your antibody development.
"The implementation of Creative Biolabs' N-Glycan Analysis Service was pivotal for our project, enabling the definitive identification of challenging positional isomers. Their specialized Middle-Up high-resolution mass spectrometry technique clearly resolved the previously co-eluting M5 and G1F-N glycoforms, yielding the precise quantitative data essential for our application." Dr. Ar** on G.
"Leveraging Creative Biolabs' FcγRIIIa affinity chromatography service was critical to mitigating potency risks for our ADC program. The analysis confirmed that our site-specific conjugation strategy did not compromise Fc-receptor interactions, thereby verifying the preserved functionality of our dual-mechanism therapeutic." J. Bol** nd.
