Abstract: Provided herein are methods for site-specific conjugation of glycan intact antibodies by a transglutaminase. According to particular embodiments, the reaction conditions are maintained or reduced to a low-ionic strength condition, which allows for efficient and fast conjugation without the need for antibody deglycosylation. Also described are pharmaceutical compositions and uses related to the conjugation method.

Abstract: A fibronectin type III (FN3) domain-nanoparticle or direct conjugate complex containing a polynucleotide molecule, a toxin, polynucleotide molecule or other pharmaceutically active payload is obtained by panning an FN3 domain library with a protein or nucleotide of interest, recovering the FN3 domain and conjugating the FN3 domain with a toxin or nanoparticle containing an active polynucleotide, such as an ASO or siRNA molecule. A fibronectin type III (FN3) domain-nucleic acid conjugate is obtained by panning an FN3 domain library with a protein or nucleotide of interest, recovering the FN3 domain and conjugating the FN3 domain to a nucleic acid (e.g., ASO or siRNA). The nanoparticle complex, nucleic acid conjugate or FN3 domain toxin conjugate may be used in the treatment of diseases and conditions, for example, oncology or auto-immune indications.
