Uses
Cy5.5-SE (Cyanine5.5 NHS ester) is a CY dye. CY, short for Cyanine, is a compound consisting of two nitrogen atoms connected by an odd number of methyl units. Cyanine compounds have the characteristics of long wavelength, adjustable absorption and emission, high extinction coefficient, good water solubility and relatively simple synthesis[1]. CY dyes are of en used for the labeling of proteins, antibodies and small molecular compounds. For the labeling of protein antibodies, the combination can be completed through a simple mixing reaction. Below, we introduce the labeling method of protein antibody labeling, which has certain reference significance[2]. Storage: protect from light.
in vivo
Cy5.5-labeled factor VIIa is developed for imagining cancer. Cy5.5 labeled with these targeting proteins specifically localize to the tumor xenografts for at least 14 days but unconjugated Cy5.5 does not localize to any xenografts or organs. This method of imaging anti-tissue factor in the tumor VECs may be useful in detecting primary tumors and metastases as well as monitoring in vivo therapeutic responses[1]. pH/temperature sensitive magnetic nanogels conjugated with Cy5.5-labled lactoferrin (Cy5.5-Lf-MPNA nanogels) are developed as a promising contrast agent for preoperative MRI and intraoperative fluorescence imaging of glioma[2].
