General description

Atto 647N is a superior red-emitting label with high molecular absorption (150.000) and quantum yield (0.65) as well as sufficient stoke′s shift. Atto 647N is characterized by a high thermal and photostability.
Absorption and fluorescence are independent of pH, at least in the most relevant range of pH 4 to 11. The amine derivative may be used for reactions with activated carboxy-groups like NHS-esters, TFP-esters etc.

Cholesterol-mediated lipid interactions are thought to have a functional role in many membrane-associated processes such as signalling events. Although several experiments indicate their existence, lipid nanodomains ('rafts') remain controversial owing to the lack of suitable detection techniques in living cells.
