Custom Anti-GM3 Antibody Service for Cancer & Metastasis Studies
GM3 Background
Ganglioside GM3 has been termed as the "entry point" ganglioside. This is in no way an understatement. As the simplest of the ganglioside family with a single sialic acid linked to lactosylceramide, GM3 has several important functions, such as the organization of lipid rafts, modulation of receptor clustering, and tuning of signaling pathways that control cell proliferation, migration, and intercellular communication. In the context of cancer, one specific variant of GM3 is of particular interest to researchers: Neu5Gc-GM3 (NGcGM3). Humans cannot make Neu5Gc naturally, yet it can build up in tumors through dietary incorporation. In fact, it is nearly undetectable in healthy tissues, which makes NGcGM3 a particularly attractive cancer biomarker. Structural insights from the well-studied antibodies 14-F7 and chP3 reveal the depth of the pocket in which the Neu5Gc residue is "locked in", completely excluding Neu5Ac. This level of pocket-mediated recognition is part of what makes GM3 a strong target for cancer immunotherapy and metastasis studies, as well as biologically fascinating. At Creative Biolabs, we use these types of insights to design anti-ganglioside antibodies. With years of glycoimmunology and antibody engineering experience, our team is well-versed in custom antibody design against complex glycans such as GM3. We use antigen design techniques, multi-platform screening, and glycan array specificity mapping in the design process, in order to provide clients with the most specific antibodies possible. For biomarker validation studies, mechanistic analyses, preclinical cancer research, and more, our scientific team and technical support can help speed your research forward. We also provide ready-to-use anti-GM3 antibodies for your quick research.

Custom Anti-GM3 Antibody Services at Creative Biolabs
We provide end-to-end custom antibody generation against GM3 and its clinically relevant variants (NGcGM3 and NA-GM3), across monoclonal, recombinant, and engineered formats. Programs are built for cancer biomarker discovery, mechanism interrogation, and translational assay development in cancer immunotherapy pipelines. Core modules include immunogen design (synthetic glycan–carrier and liposomal display), discovery by hybridoma/yeast or phage display, multi-tier specificity screening (glycan array, TLC-overlay, cell-based), affinity maturation and humanization, and RUO assay development (IHC/IF, ELISA, FC, SPR/BLI).

FAQs
How do you ensure selectivity between NGcGM3 and NA-GM3?
We bias immunogens to expose the terminal Neu5Gc or Neu5Ac, then screen on both forms, use glycan arrays to separate binders, and confirm in cells and tissues. Structural literature shows a deep pocket in anti-NGcGM3 clones that disfavors Neu5Ac.
Will the antibody cross-react with GD3 or GM2?
We include ganglioside panels (GM1, GM2, GD3, GD2) and asialo controls in primary screens, followed by array-based mapping. Only clones passing pre-set cross-reactivity thresholds progress to engineering and validation.
Is Neu5Gc-GM3 really tumor-associated in humans?
Yes. Humans cannot produce Neu5Gc, but it can be incorporated from dietary sources. Elevated Neu5Gc-GM3 has been detected in several cancers, including breast cancer and melanoma, while remaining rare in healthy tissues—making it a valuable cancer biomarker.
Can GM3 antibodies be used for metastasis studies?
Absolutely. GM3 has been linked to tumor cell adhesion and invasion. By using antibodies to identify GM3-positive subpopulations, researchers can track how these cells migrate, invade, and contribute to metastatic behavior.
What kind of deliverables do I receive at the end of a project?
We provide more than just antibodies. Clients receive hybridoma or recombinant clones, validated sequences, purified antibody samples, and detailed SOPs covering ELISA, IHC, IF, or flow cytometry—making it easy to continue studies in-house.
Can the antibodies be humanized for translational research?
Yes. We routinely engineer and humanize promising clones while preserving the structural features that enable Neu5Gc-specific recognition. Deliverables include humanized IgG formats with validation data to support further research.
