MedKoo CAT#: 555730

CAS#: 1392488-07-1

Description: QUN88071 is a water soluble Near-Infrared Fluorescent Sensor for in Vivo Imaging. QUN88071 is soluble in pure PBS and newborn calf serum (without addition of any co-organic solvent) with a solubility of at least 2 mM in PBS and 3 mM in newborn calf serum. The unique optical properties of the new type of fluorescent dyes can be exploited as a useful strategy for development of NIR fluorescent sensors. This product has not formal name. For the convenience of scientific communication, we named it by combining its Inchi key (3 letters from the first letter of each section) with the last 5 digit of its CAS#) according to MedKoo Chemical Nomenclature (https://www.medkoo.com/page/naming).

Additional Information

Fluorescence imaging is a very powerful technique for localization and dynamic monitoring of biomolecules in living systems. The development of new fluorescent imaging sensors has facilitated the recent significant advances in cell biology and medical diagnostic imaging. Near-infrared (NIR) light (650−900 nm) is advantageous to be employed in biological imaging due to minimum photodamage to biological samples, deep tissue penetration, and minimum interference from background autofluorescence by biomolecules in the living systems.
