CyGbPF is efficiently cleared by the kidneys, enabling the assessment of immune activation via optical urine analysis. CyGbPF allows real-time non-invasive evaluation of cancer immunotherapeutic efficacy in living animals. CyGbPF can be used in research on cancers such as breast cancer. Excitation wavelength/emission wavelength: approximately 658 nm/approximately 717 nm.

CDg16 is a selective fluorescent dye targeting SLC18B1 (λ_abs/λ_em=458/544 nm) that is actively transported into lysosomal vesicles of activated macrophages independent of the endocytic pathway. CDg16 enables highly specific vesicle localization in live cells. CDg16 exhibits no cytotoxicity and accurately distinguishes activated M1 and M2 subsets from different origins. CDg16 shows low background staining in non-activated cells and normal organs, making it suitable for time-lapse imaging. In preclinical animal models of inflammatory sites, atherosclerotic plaques and liver inflammation, CDg16 allows visualization of activated macrophages. CDg16 can be used to study inflammation-related diseases and atherosclerosis.

HJTA is a selective, pH/GSH dual-responsive Fluorescent probe and anticancer agent. HJTA selectively undergoes an enzymatic reaction with GSTπ. HJTA induces Apoptosis and Autophagy by regulating the expression of apoptotic and autophagic proteins. HJTA exhibits pH- and GSH-dual-responsive fluorescence in tumor cells. HJTA selectively illuminates tumor tissues, enabling precise in situ visualization of colon tumors. HJTA exerts anticancer effects against colon cancer. HJTA can be used for colon cancer research.

AldeRed 588-A is a fluorescent labeling reagent and a substrate for aldehyde dehydrogenase (ALDH). AldeRed 588-A is metabolized by functionally active ALDH enzymes, thereby specifically labeling viable ALDH^bright cell populations with red-shifted fluorescence. AldeRed 588-A supports one-step isolation and sorting of ALDH-expressing cells (including normal stem cells and cancer stem cells), and can be used in combination with green fluorophores for multicolor experimental applications. AldeRed 588-A is widely applicable to research related to various cancers such as bladder cancer, breast cancer, and head and neck cancer.

BODIPY-DOX is a conjugate composed of BODIPY and Doxorubicin (HY-15142A), as well as a pH-activated fluorescent probe for M1 macrophages and an apoptosis inducer. BODIPY-DOX undergoes pH-induced hydrazone bond cleavage in acidic M1 macrophage phagosomes, thereby releasing cytotoxic Doxorubicin (Dox) and inhibiting the function of pro-inflammatory M1 macrophages. BODIPY-DOX highly selectively inhibits the production of relevant pro-inflammatory cytokines by mouse and human monocyte-derived M1 macrophages, while exerting minimal effects on M2 or unactivated macrophages. Therefore, BODIPY-DOX enables simultaneous fluorescent tracing, differentiation and elimination of specific macrophage subsets, and exhibits the potential to regulate tissue regeneration in zebrafish models.

oLOX is a fluorescent activity reporter. oLOX can be activated by lysyl oxidase family (LOXF) enzymes, which in turn releases a luciferin fluorescent product that reports LOXF enzyme activity. After oLOX is activated in in vitro fibrotic lung tissues, the fluorescence intensity increases, enabling real-time detection of fibrotic activity. oLOX can be used in studies related to pulmonary fibrosis.

HOTN is a hypochlorous acid (HClO) Fluorescent indicator. HOTN is oxidized by HClO, causing cleavage of its Py⁺-N⁺ moiety and a change in hydrophobicity, which in turn triggers aggregation-induced emission to generate a strong fluorescent signal. HOTN is used for in vivo imaging of inflammation and hepatocellular carcinoma, as these diseases typically result in high levels of HClO.

PiF is a fluorescent probe with high specificity for pancreatic β-cells (Ex/Em = 535 nm/565 nm), and its fluorescence signal increases significantly with elevated insulin concentrations in in vitro experiments.
