Application

Atto 540Q is a new quencher for fluorescence characterized by high molecular absorption (105.000). Atto 540Q is characterized by a high photostability and thermostability. It is moderately hydrophilic, and soluble in polar solvents as DMF or DMSO. Atto 540 Q NHS ester is used to label molecules such as proteins via conjugation to primary amine groups.

Numerous synthetic fluorophores have been developed that can switch their spectroscopic properties upon interaction with other molecules or by irradiation with light. In recent years, protein-labeling techniques have been introduced that permit the specific attachment of such molecules to proteins...
