    Jan 30, 2015 · Delivery of siRNA is a key hurdle to realizing the therapeutic promise of RNAi. By targeting internalizing cell surface antigens, antibody–siRNA complexes provide a possible solution. However, initial reports of antibody–siRNA complexes relied on non-specific charged interactions and have not been broadly applicable.Author: Trinna L. Cuellar, Dwight Barnes, Christopher Nelson, Joshua Tanguay, Shang-Fan Yu, Xiaohui Wen, Suz...

Site-specific Antibody-polymer Conjugates for siRNA Delivery

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3955097/
    Sep 18, 2013 · We describe here the development of site-specific antibody-polymer conjugates (APCs) for the selective delivery of small interference RNAs (siRNAs) to target cells. APCs were synthesized in good yields by conjugating an aminooxy-derivatized cationic block copolymer to an anti-HER2 Fab or full length IgG by means of genetically encoded para -acetyl phenylalanine ( p AcF).Author: Hua Lu, Danling Wang, Stephanie Kazane, Tsotne Javahishvili, Feng Tian, Frank Song, Aaron Sellers, B...

    Mar 15, 2015 · Systemic delivery of antibody–siRNA complexes is feasible as has been demonstrated for an anti-CD7-siRNA construct that was used to treat HIV infection in humanized mice . This construct was based on a scFV single chain antibody with a c-terminal histidine that was coupled to a small cationic peptide via a disulfide bond.Author: Sebastian Bäumer, Nicole Bäumer, Neele Appel, Lisa Terheyden, Julia Fremerey, Sonja Schelhaas, Eva W...

    Therefore, antibodies against internalizing receptors have been thought to be a possible targeting ligand for siRNA delivery. There are two types of delivery platforms available: 1) a covalently bound antibody-siRNA conjugate and; 2) a non-covalently bound complex of siRNAs and cationic peptide-modified antibodies . Considering the manufacturing process, antibody siRNA conjugates provide a single entity without optimizing various factors, such as the siRNA…Author: Tsukasa Sugo, Michiko Terada, Tatsuo Oikawa, Kenichi Miyata, Satoshi Nishimura, Eriya Kenjo, Mari Og...

    Apr 18, 2012 · However, the efficient delivery of siRNAs into cancer cells in vivo remains a major obstacle. An antibody fragment fused to an RNA binding protamine peptide specifically delivered siRNAs and knocked down gene expression in cells bearing a cell surface protein recognized by the antibody.Author: Yan-dan Yao, Tian-meng Sun, Song-yin Huang, Shuang Dou, Ling Lin, Jia-ning Chen, Jian-bin Ruan, Chen...

    Sep 10, 2019 · Monoclonal antibody (mAb) targeting of siRNAs and ASOs has the potential to deliver these drugs to a variety of specific cell and tissue types. However, most conjugation strategies rely on random chemical conjugation through lysine or cysteine residues resulting in conjugate heterogeneity and a distribution of Drug:Antibody Ratios (DAR).Author: Ian J.
