Sulfo-Cyanine5.5 is a dye with far-red emission approaching NIR range. It has found application in non-invasive live-organism imaging. This particular derivative of sulfo-Cyanine5.5, the DBCO (or ADIBO) derivative, contains cycloalkyne for copper-free conjugation of this fluorophore with various organic azides.
The reaction between DBCO and azides is blazingly fast, orders of magnitude exceeding the rate of copper-catalyzed reaction between azides and terminal alkynes. It is also catalyst-free.
This reagent can be used to conjugate sulfo-Cyanine5.5 dye to a variety of azide-labeled molecules.
Sulfo-Cy5.5 是一种具有接近 NIR 范围的远红发射的染料。 它已在非侵入性活体成像中得到应用。 这种特殊的磺基-Cyanine5.5 衍生物，即 DBCO（或 ADIBO）衍生物，含有环炔烃，用于无铜共轭这种荧光团与各种有机叠氮化物。
DBCO 和叠氮化物之间的反应非常快，数量级超过了铜催化的叠氮化物和末端炔烃之间的反应速率。 它也不含催化剂。
该试剂可用于将磺基-Cyanine5.5 染料与多种叠氮化物标记的分子结合。
