Bright-Dtech™ 575 – Dy (Yellow) Coupled to Biotin
With Bright-Dtech™, we offer you an innovative solution to have a higher detection sensitivity with easy-to-use protocols, applicable in various molecular and cellular biology techniques. They are ultra-efficient fluorescent nano-molecules with unique characteristics.
Biotin is a co-enzyme which has a strong affinity with Streptavidin. Our experts have therefore been able to take advantage of the link to offer you a product that meets your expectations which can be used in many detection protocols such as protein assays on microplates, Western Blot, flow cytometry, imaging and microscopy.
Due to lanthanide’s fingerprinting emission spectrum, Bright-Dtech™ – Dy (Yellow) can be incorporated with other Bright-Dtech™ nanoparticles to achieve multiple detection of biomarkers or proteins in the same biological sample.

Ultra-bright lanthanide nanoparticles
Terbium-doped LaF3 nanoparticles, surface-functionalized by photon-harvesting antenna ligands. Surface capping with antenna ligands leads to ultrabright nanoparticles, with the typical green luminescence signature of Tb atoms and very long excited-state lifetimes

Live cell imaging without autofluorescence using terbium nanoparticles
Application of a new type of surface photosensitized terbium NPs (Tb-NPs) for autofluorescence-free intracellular imaging in live HeLa cells. Combination of exceptionally high brightness, high photostability, and long photoluminescence (PL) lifetimes for highly efficient suppression of short-lived autofluorescence, enabling timed PL imaging of intracellular vesicles over 72 h without toxicity and at extremely low concentrations of Tb-NP for up to 12h.
