Enhanced stability of horseradish peroxidase encapsulated in acetalated dextran microparticles stored outside cold chain conditions.

Micro- and nanoparticles have been shown to improve the efficacy of safer protein-based (subunit) vaccines. Here, we evaluate a method of improving the vaccine stability outside cold chain conditions by encapsulation of a model enzyme, horseradish peroxidase (HRP), in an acid-sensitive, tunable biodegradable polymer, acetalated dextran (Ac-DEX). Vaccines… CONTINUE READING
