IR 780 is a heptamethine cyanine fluorescent probe for in vivo imaging of tumor cells.{59759} It displays excitation/emission maxima of 780/799 nm, respectively.{59760} IR 780 is transported into tumor cells, an effect that can be blocked by the organic anion transporting polypeptide (OATP) inhibitor sulfobromophthalein (bromosulfalein; Item No. 21058), and targeted to the mitochondria.{59759} It has an additive effect on the increase in reactive oxygen species (ROS) production induced by sonodynamic therapy (SDT) in 4T1 breast cancer cells when used at a concentration of 16 µM.{59761} IR 780 (0.2 mg/kg, i.v.) preferentially accumulates in tumor tissue in MCF-7, HeLa, and MG-63 mouse xenograft models and in a syngeneic mouse model of chemically induced lung tumors, and its fluorescence is detectable for up to 20 days. It also has an additive effect on the SDT-induced reduction in tumor growth in an 4T1 murine mammary carcinoma model. IR 780 has been incorporated into heparin-folic acid-IR 780 nanoparticles for use in photothermal therapy.{59762}

Cayman Chemical’s mission is to help make research possible by supplying scientists worldwide with the basic research tools necessary for advancing human and animal health. Our utmost commitment to healthcare researchers is to offer the highest quality products with an affordable pricing policy.
Our scientists are experts in the synthesis, purification, and characterization of biochemicals ranging from small drug-like heterocycles to complex biolipids, fatty acids, and many others. We are also highly skilled in all aspects of assay and antibody development, protein expression, crystallization, and structure determination.
Over the past thirty years, Cayman developed a deep knowledge base in lipid biochemistry, including research involving the arachidonic acid cascade, inositol phosphates, and cannabinoids. This knowledge enabled the production of reagents of exceptional quality for cancer, oxidative injury, epigenetics, neuroscience, inflammation, metabolism, and many additional lines of research.
Our organic and analytical chemists specialize in the rapid development of manufacturing processes and analytical methods to carry out clinical and commercial GMP-API production. Pre-clinical drug discovery efforts are currently underway in the areas of bone restoration and repair, muscular dystrophy, oncology, and inflammation. A separate group of Ph.D.-level scientists are dedicated to offering Hit-to-Lead Discovery and Profiling Services for epigenetic targets. Our knowledgeable chemists can be contracted to perform complete sample analysis for analytes measured by the majority of our assays. We also offer a wide range of analytical services using LC-MS/MS, HPLC, GC, and many other techniques.
