Bright-Dtech™ 545 – Tb (Green) Coupled to Anti-Rabbit IgG (H + L)
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.
Secondary antibodies aim to detect and visualize a primary antibody that is bound to its protein of interest. Rabbit antibody is often used in applications such as ELISA, Western Blot, IHC, or cell imaging.
If you are using a primary antibody produced in rabbits, you will choose as the secondary antibody an anti-rabbit antibody produced in a species other than rabbit.
Due to lanthanide’s fingerprinting emission spectrum, Bright-Dtech™ – Tb (Green) 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.
