Cyanine5.5 dye, free acid form, unactivated. The dye can be considered non-reactive for most applications. It can be used as a control or reference sample, and for instrument calibration.
Pre-activated NHS ester for the labeling of amine groups is also available.
Sulfo-Cyanine5.5 is a far red/NIR fluorophore possessing high hydrophilicity and aqueous solubility. The dye displays good brightness in far red region due to outstanding molar extinction coefficient. This is amine derivative which is reactive towards electrophiles. It can also be used for enzymatic transamination labeling.
