UGO 700 NHS ester [equivalent to ATTO 700 NHS ester]

UGO 700 is a near-infrared fluorescent dye distinguished by its strong absorption, high photo and thermal stability, and excellent aqueous solubility. It is optimally excited within the 670-715 nm wavelength range. As a zwitterionic compound, UGO 700 remains electrically neutral when conjugated to biomolecules or other substrates. Its strong electron-accepting properties enable efficient fluorescence quenching by electron donors such as guanine and tryptophan. These characteristics make UGO 700 highly suitable for precision applications, including single-molecule detection and super-resolution microscopy techniques like PALM, dSTORM, and STED. Additionally, UGO 700 is compatible with flow cytometry (FACS), fluorescence in situ hybridization (FISH), and a wide range of other biological assays, solidifying its role as a versatile and indispensable tool in advanced fluorescence-based research.
