产品介绍
Cyanine5 NHS ester bromide 是一种活性染料,用于标记肽、蛋白质和寡核苷酸中的氨基。Cyanine5 NHS ester bromide 作为一种菁染料,可应用于通过精氨酸残基荧光标记神经紧张素 (8-13) 。
生物活性

Cyanine5 NHS ester bromide is a active compound, can be used to label amino groups inpeptides, proteins, andoligonucleotides. Cyanine5 NHS ester bromide is a cyanine dye, fluorescence-labeling neurotensin (8-13) via arginine residues[1].

体外研究
(In Vitro)

Cyanine5 NHS ester bromide can be excitable with a red (635 nm) and a 488 nm argon laser, respectively[1].
Cyanine5 NHS ester bromide applys for characterization[1]:
1. Acquire high resolution mass spectra (HRMS) with Agilent 6540 UHD Accurate-Mass QTOF LC/MS system coupled to an Agilent 1290 HPLC system, using an ESI source.
2. Perform preparative HPLC with a system from Knauer (Berlin, Germany). A Kinetex-XB C18, 5 μm, 250 × 21 mm (Phenomenex, Aschaffenburg, Germany) is used as stationary phase. Mixtures of 0.1% aq TFA and acetonitrile are used as mobile phase. The flow rate is 18-20 mL/min, and a detection wavelength of 220 nm is used throughout.
3. Analysis HPLC with a system from Agilent Technologies. A Kinetex-XB C18, 2.6 μm, 100 × 3 mm (Phenomenex) serves as stationary phase at a flow rate of 0.5-0.6 mL/min. The oven temperature is set to 25 ℃. Mixtures of 0.04% aq TFA and acetonitrile are used as mobile phase. The injection volume is 20 μL. Detection is performed at 220 nm.
