Transiently responsive protein-polymer conjugates via a 'grafting-from' RAFT approach for intracellular co-delivery of proteins and immune-modulators

Chem Commun (Camb). 2015 Sep 21;51(73):13972-5. doi: 10.1039/c5cc04809e.

Abstract

We report on transiently responsive protein-polymer conjugates that temporarily change their protein conformation from the soluble to the particle-like state. 'Grafting-from' RAFT polymerization of a dioxolane-containing acrylamide with a protein macroCTA is used to design polymer-protein conjugates that self-assemble into nanoparticles at physiological temperature and pH. Acid triggered hydrolysis of the dioxolane units into diol moeities rendered the conjugates fully water soluble irrespective of temperature.
