An easily available endoplasmic reticulum targeting near-infrared fluorescent probe for esterase imaging in vitro and in vivo

Abstract

Here, we report an easily available endoplasmic reticulum-targeting near-infrared fluorescent probe (ER-CE), which can detect esterase in the endoplasmic reticulum and monitor the changes in the esterase amount in tumors in mice in real time. These results indicate that ER-CE is expected to become a powerful analysis tool for the research of endoplasmic reticulum esterase-related diseases.
