Cyanine5.5 NHS ester is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides, an analog of Cy5.5® NHS ester.
Cy5.5 is a far-red (and near-infrared) emitting dye which is ideal for fluorescence measurements where background fluorescence is a concern. It is also suitable for in vivo NIR imaging experiments.
This reagent can replace NHS esters of Cy5.5® and DyLight 680.

Amino-11-dUTP
Amino-11-dUTP is a triphosphate for the modification of DNA.Sulfo-Cyanine5.5 amine
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.General properties
