An anti-CDw75 monoclonal antibody is provided that recognizes “CDw75” sugar chain structures but does not recognize similar sugar chain structures indicated by “Galβ1,4GlcNAc”, “Siaα2,3Galβ1,4GlcNAc”, or “Siaα2,6Galβ1,4Glc”, by using a glycolipid antigen bonding a carrier lipid compound “HOCH2CH(NH—CO—(CH2)22—CH3)—(CH2)9—CH3 (C12L)” developed by the inventors to a “CDw75” sugar chain. The obtained anti-CDw75 monoclonal antibody is an excellent detection drug for B-cell lymphoma, gastric cancer, or colorectal cancer, an excellent diagnostic agent for tumor malignancy, etc., an excellent treatment agent for B-cell lymphoma, gastric cancer, or colorectal cancer, and an excellent prevention/treatment drug for influenza."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Monoclonal antibody recognizing sialylated sugar chains","description":"The purpose of the present invention is to provide a novel monoclonal antibody having high affinity and that strictly recognizes, as a sugar chain epitope, only a “Siaα2,6Galβ1,4GlcNAc (6′-Sialyl-LacN","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9796785","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
