Flamma® 552 Carboxylic acid

Flamma® Fluors 552 Carboxylic acid is inactive form of bright yellow fluorescent dye induced from cyanine structure and used to generate a stable fluorescence signal in bioimaging. Flamma 552 fluorophore is attached with the octanoic acid. The maxima of Ex/Em values are at 550/564 nm, similar to that of Alexa 555, DyLight 549, ATTO 550 and Cy3. Flamma 552 might be excited using 532, 543, 546 or 555 nm laser lines and displays excellent optical property. Flamma 552 acid might be coupled with primary amine at small molecules or on biomolecules by standard amide bond coupling conditions, or it might be converted to a reactive amine form by using standard chemical techniques. Flamma® Fluors 552 acid can be utilized as a reference standard for dye-conjugates.
