AIE-ER is a specialized fluorescent probe for the endoplasmic reticulum (ER) that operates in the green channel with excitation at λ ex =405 nm and emission between λ em =450~650 nm. It is notable for its exceptional photostability, high brightness, and low working concentration, potentially facilitating research into ER-related diseases [1].

AIE-ER在HeLa细胞中表现出较低的细胞毒性（1-10 μM; 24 h），即使浓度达到10 μM时，细胞活性仍保持在75%以上[1]。
