Descrizione generale

Atto 495 is a new label for proteins and oligo-nucleotides with high molecular absorption (80.000) and quantum yield (0.45) as well as sufficient Stoke′s shift between excitation and emission maximum. Atto 495 is characterized by a high photostability and thermostability. It is slightly hydrophilic, and solubility in polar solvents as DMF or DMSO is high.

Applicazioni

Atto 495 is a lipophilic fluorescent compound, which has served as the neutral analyte in the model, along with SDS as the charged micelle acting as a carrier to transport this solute in an electric field[1][2]. Atto 495 was included as fluorescence EOF marker for chip electrophoresis. This reagent is zwitterionic at pH 8.3 and thus migrates as a neutral substance under the proper conditions[3][4].
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.
