Descripción

Descripción general

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.

Aplicación

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. 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.

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.
