Opis

General description

Atto 425 is a member of the commercially available coumarin derivatives.

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.

Other Notes

Study of stability during one- and two-photon excitation in fluorescence correlation spectroscopy, FCS; employed in triple-color coincidence analysis[1].
