On March 4, 2021, Dabora, Rebecca; Dingley, Amy; Patel, Suman; Swiss, Gerald F. published a patent.HPLC of Formula: 130539-43-4 The title of the patent was Tetanus toxoid and other antimicrobial vaccine compositions providing natural immunity against microbes with N-acetyl-β-(1->6)-glucosamine in cell wall. And the patent contained the following:
This invention is directed to antimicrobial vaccine compounds and compositions comprising oligosaccharide β-(1→6)- glucosamine groups having from 3 to 12 glucosamine units linked through a linker group to tetanus toxoid wherein the toxoid is primarily in its monomeric form. This invention is also directed to vaccine compositions that provide natural immunity against microbes possessing a cell wall structure that comprises oligosaccharide N-acetyl-β-(1→6)-glucosamine (PNAG) structures. The experimental process involved the reaction of Ethyl 2-deoxy-2-(1,3-dihydro-1,3-dioxo-2H-isoindol-2-yl)-1-thio-beta-D-glucopyranoside(cas: 130539-43-4).HPLC of Formula: 130539-43-4
The Article related to antimicrobial vaccine cell wall beta glucosamine antigen oligosaccharide, tetanus toxoid vaccine oligosaccharide beta glucsosamine, Immunochemistry: Adjuvants, Antigens, Haptens, and Vaccines and other aspects.HPLC of Formula: 130539-43-4
