Atto 647

BioChemika, for fluorescence, ≥90% (HPCE)

Descriptions

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.

General description

Atto 647 is a new label with high molecular absorption (120,000) and quantum yield (0.20) as well as sufficient Stokes shift between excitation and emission maximum. Atto 647 is characterized by a high photostability.
