Ionic liquids as stabilisers of therapeutic protein formulations: a review of insulin and monoclonal antibodies.

Therapeutic proteins such as insulin and monoclonal antibodies (mAbs) have become an essential part of the modern healthcare system and play a crucial role in the treatment of various diseases including cancer and autoimmune disorders. However, their long-term stability is a significant concern, affecting efficacy, shelf-life, and safety. Ionic liquids (ILs) have emerged as promising additives to enhance protein stability and address the aforementioned issues.
