Patent ID: 10378017

Abstract:
The invention relates to an oligonucleotide including one or more modified nucleoside bases having the structure -B-L-A wherein for each of the modified nucleosides A is independently a monosaccharide or oligosaccharide, L is a linker molecule, and B is independently a pyrimidine or pyridine base linked to the sugar-phosphate backbone of the oligonucleotide; and wherein the oligonucleotide binds specifically to a carbohydrate-binding monoclonal antibody with an affinity of less than 100 nM. Immunogenic conjugates that include the oligonucleotide, and pharmaceutical compositions that include the oligonucleotide or the immunogenic conjugate are also disclosed. Various method of using the oligonucleotides, immunogenic conjugates, and pharmaceutical compositions are disclosed, including inducing an immune response, inhibiting viral or bacterial infection, treating a cancerous condition, and detecting a neutralizing antibody. A method is also disclosed for selecting the oligonucleotides using an alternative Selection of Modified Aptamers (SELMA).
