Novel Polymeric Nanogels for Controlled Intracellular Protein Delivery and Traceless Release

PRODUCT OPPORTUNITIES

• Nanogel encapsulated protein prodrugs or therapeutics
• Nanogel encapsulated diagnostic agents
• Protein encapsulation reagents and kits for intracellular delivery and traceless release

PRODUCT OPPORTUNITIES

COMPETITIVE ADVANTAGES

• Broadly applicable protein encapsulation and delivery technology (capable of encapsulating proteins with surface exposed lysine residues which are present on the surface of >85% of globular proteins)
• High protein encapsulation fidelity and loading capacity
• High protein stability against degradation by proteases
• High-fidelity protein delivery into the cytosol
• Stimuli-responsive, traceless release of the encapsulated proteins in the cytosol

TECHNOLOGY DESCRIPTION

This invention provides a new class of polymeric nanogels that are capable of encapsulating proteins for controlled intracellular delivery and releasing them in the cytosol. The nanogels are degraded under the cytosolic, reducing conditions, resulting in traceless release of the intact protein molecules that retain their native conformation, activity and function.
