Description

General description

Atto 425 is a new label with high quantum yield (0.90) as well as sufficient stoke′s shift (excitation maximum 436 nm, emission maximum 484 nm). It is optimized for excitation with argon laser, and is characterized by high photostability. It does nearly not show cis-trans-isomerization, which limits brightness and reproducibility for many other dyes.

Application

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. Atto 425 biotin is suitable for fluorescence labeling of avidin/streptavidin conjugated molecules.
