Process for inserting targeting ligand into a lipid nanoparticle encapsulating nucleic acid and compositions produced therefrom

Abstract

Methods for inserting a targeting moiety (such as an antigen-binding protein moiety, a fragment antigen-binding moiety, or the like) into a lipid nanoparticle and compositions resulting from such methods are provided. The methods generally utilize a reaction that forms targeted nanoparticles by combining a targeting moiety and a lipid nanoparticle. A quenching operation is then provided by cooling the reaction to a temperature that stops the insertion of the targeting moiety. The reaction substantially preserves the integrity of a nucleic acid cargo (such as an mRNA encoding a VHH binding molecule).
