Choline ionic liquid enhances the stability of Herceptin® (trastuzumab)†
Abstract
We investigated the effect of an emerging biocompatible ionic liquid, choline dihydrogen phosphate (CDHP), on the stability of high-concentration formulations of Herceptin® (trastuzumab). Our results show that CDHP significantly suppresses unfolding and aggregation of trastuzumab, demonstrating great promise as an additive in the development of stable therapeutic antibody formulations.
