Currently, several categories of probes have been studied, which generally include organic NIR dyes such as cyanine
dyes, rhodamine dyes, BODIPY-based NIR probes, squaraine-based NIR probes, phthalocyanines and porphyrin derivatives, and nanoprobes such as NIR dye-containing nonmetallic nanoparticles, gold nanostructures, and quantum dots.
Shahedi, Novel Ag/Kaolin Nanocomposite as Adsorbent for Removal of Acid Cyanine
5R from Aqueous Solution, J.
Attributes/comments: Allows for enhance absorption to the sparsely functional, yet electron-rich surface of difficult to disperse organic pigments such as PR 179 (perylene), PB 15:1 (phthalo cyanine
blue) and PBk 7 (high-jetness carbon black) in water-based systems, resulting in lower pigment particle size, stronger color development and lower viscosity.
The researchers used Sybr[R] Green, an asymmetrical cyanine
dye used as a nucleic acid stain.
dyes could improve the efficiency of molecular probes in identifying, for example, the presence of a virus or a tumor receptor.
Total RNAs were isolated from the cells using Trizol (Invitrogen, Carlsbad, CA, USA) and amplified with cyanine
3 (Cy3)- or Cy5-labeled CTP.
dye could accumulate in the mitochondrial matrix under the influence of MMP.
A-Band fluorescence, excitation of the protonated chromophore of the fluorescent protein; B-Band fluorescence, excitation of the deprotonated chromophore form of the fluorescent protein: CFP, cyan fluorescent protein; Cy5, cyanine
dye; YFP, yellow fluorescent protein.
dye is used for determining cardiac output, hepatic function, liver- blood flow and for ophthalmic angiography, it is also considered to be of potential help in treatment of various cancers.
Briefly, protein (50 g) was labeled with 400 pmol of amine reactive cyanine
The design of the assay included fluorescent detection at 540 nm, based on using urine protein samples labeled with a green fluorescent dye, Cyanine
To determine whether CPT and NPOA cotreatment-induced apoptosis of NSCLC cells was through the modulation of mitochondria-mediated apoptosis pathway, JC-1, a cyanine
dye, was used to detect the depolarization of mitochondrial membrane potential (MMP), a hallmark of mitochondrial-mediated apoptosis .
