Sulfo-Cy5 DBCO是一个近红外 (NIR) 红色荧光染料 λabs和 λem 值分别为646 nm 和 670 nm。Sulfo-Cy5 DBCO不适合对通透性细胞的胞内成分进行染色，可能会表现出较高的背景。Sulfo-Cy5 DBCO 是一种点击化学试剂。它含有 DBCO 基团，可以和含有 Azide 基团的分子发生环张力 (strain) 促进的炔-叠氮环加成反应 (SPAAC)。 Sulfo-Cy5 DBCO is a near-infrared (NIR)red fluorescent dye with λabsand λem of 646nm and 670 nm, respectively. Sulfo-Cy5 DBCO is not suitable for staining intracellular components of permeabilezed cell, it may exhibits a high background. Sulfo-Cy5 DBCO is a click chemistry reagent, it contains a DBCO group that can undergo strain-promoted alkyne-azide cycloaddition (SPAAC) with molecules containing Azide groups. Extinction Coefficient Excitation Maximum: 250000; Sulfo-Cy5 DBCO is a water-soluble derivative of Cyanine5 fluorophore. DBCO group enables copper free biocompatible Click Chemistry with fast reaction kinetics and good stability. This reagent is compatible to a wide range of standard fluorescent instrumentation such as imagers, plate readers, and microscopes.
