Descripción general

ATTO 425 NHS ester is a new fluorescent marker based on the Rhodamine structure. It has strong absorption, high fluorescence quantum yield, high thermal stability and photochemical stability, and is suitable for single molecule detection and high-resolution microscopy. ATTO 425 NHS ester is an NHS ester derivative of ATTO 425 that can be used to label proteins or antibodies.

Application:

Atto 425 NHS ester is used in the development of bifunctional fluorescent, inorganic micro-partices (Zeolite L crystals) designed for targeting or imaging mutliple components . Reacts with amino groups or amine modified oliognucleotides to form a stable amine bond. Utilized as an essential component of molecular beacons, which were designed for use in real-time PCR assays to allow for rapid and accurate identification of gram-negative bacteria . When conjugated with benzylguanine, the fluorescence of Atto 425-NHS is quenched but becomes fluorescent upon labeling of the SNAP-tag fusion protein, making this conjugate an ideal candidate for experiments in living cells . Used as one of the donor probes in three-color FRET experiments designed to investigate the kinetics of RNA-protein complex formation .
Atto fluorescent labels are designed for high sensitivity applications, including single molecule detection. Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation.
