CY5-Dextran (MW60-80k) is a fluorescent probe formed by covalent conjugation of the cyanine dye Cy5 to dextran. It is a pH-insensitive fluid-phase endocytosis tracer (the pH of endosomal lumen is precisely quantified by the fluorescence ratio of FITC/Cy5). CY5-Dextran (MW60-80k) is internalized by cells via a clathrin-independent fluid-phase pinocytosis pathway, and is sequentially evidenced by early endosomes, late endosomes are transported to lysosomes. CY5-D I cannot pass through the limited pore size formed by uncoating of human rhinovirus type 2 (HRV2), but can be released into the neutral cytoplasm upon adenovirus-mediated endosomal rupture, thus distinguishing between the two viral modes of "pore-forming escape" and "lysis escape". CY5-Dextran (MW60) -80k) has an excitation wavelength of 635 nm, and it can also be used for time-lapse imaging of endocytosis dynamics of stromal cells in tissues such as rat salivary glands under in vivo two-photon microscopy .

Lyso-OC is a two-photon fluorescent probe that enables real-time monitoring of autophagy through ultrasensitive detection of lysosomal polarity changes. Lyso-OC possesses a coumarin (HY-N0709) solvatochromic group and a morpholine lysosome-targeting group, allowing selective lysosomal localization in living cells. Lyso-OC emits strong fluorescence in low-polarity lysosomes, whereas in high-polarity autolysosomes formed during autophagy, its fluorescence intensity decreases and the emission peak shifts by approximately 30 nm.
