Abstract

Provided herein are coacervate compositions including cytokines, and methods of making and using the same. The coacervate can be formed by the mixing of an active agent, such as a drug or protein with the polyanion, such as heparin or heparan sulfate, and a custom-made polycation (e.g., PEAD or PELD). The coacervates can be used in the treatment of diseases and disorders where targeted treatment is desired, for example in treatment of cancers.
