D-虫荧光素钾盐
Luciferin is a common bioluminescent reporter used for in vivo imaging of the expression of luciferase. This water soluble substrate for the firefly luciferase enzyme utilizes ATP and Mg2+ as cofactors to emit a characteristic yellow-green emission in the presence of oxygen, which shifts to red light in vivo at 37°C. Through the utilization of ATP, the reaction can be further used to indicate the presence of energy or life in order to function as a life-death stain.
SulfoCy7（=Cy7 ）
Cyanine dyes are a series of reactive fluorescent dyes that are widely used for labeling peptides, proteins, nucleotides and nucleic acids.
Good water solubility enables labeling reactions conveniently run in aquesous media without using organic solvents (such as DMF or DMSO) as co-solvent
Low non-specific binding of resultant conjugates facilitate the assay development
A wide range of excitation and emission wavelengths makes them available for versatile fluorescence instruments

SulfoCy5.5 SE（=Cy5.5 NHS=Cy5.5 SE）
Sulfo Cy5.5 SE=Cy5.5 NHS ester dyes has been wide used to label biological molecules for fluorescence imaging and other fluorescence-based biochemical analysis. Cy5.5 NHS ester is a reactive dye readily reacts with amino groups for the labeling of amino-groups in peptides, proteins, and oligonucleotides. It is a water soluble and hydrophilic dye for the far-red part of the spectrum. The dye has four sulfo groups which give it a negative charge at physiological pH values. The dye can be used for in vivo imaging and applications that demand low fluorescent background. Cy5.5 is a far-red (and near-infrared) emitting dye which is ideal for fluorescence measurements where background fluorescence is a concern. It is also suitable for in vivo NIR imaging experiments. Upon attachment to biomolecules (for example oligonucleotides), negligible shifts in excitation and emission wavelength have been observed.
SulfoCy7 SE（=Cy7 NHS=Cy7 SE）
Cy7 NHS is water soluble near infrared dye，specially useful for NIR imaging. Water soluble Cyanine Cy7 NHS ester is for the labeling of various amine-containing molecules in aqueous phase without use of any organic co-solvent. This water soluble near infrared dye is therefore particularly useful for the labeling of pepties, proteins and oligos etc which denature in the presence of organic co-solvents, as well as for proteins with low solubility. This dye is highly hydrophilic and water-soluble. Near infrared fluorescent imaging takes advantage of transparency of biological tissues at particular range of wavelengths. The method is non-destructive, and allows to monitor distribution of various labeled molecules in live organisms. Sulfo-Cyanine7 NHS ester reagent allows to prepare sulfo-Cyanine7-labeled biomolecules, such as proteins, with ease. Dye labeled molecules can be subsequently used for various research and drug design related experiments.
Super Fluor 647 SE（～Alexa Fluor 647 SE）
Super Fluor® dyes are the ideal substitute for Alexa Fluor dyes. Super Fluor® dye are a series of superior fluorescent labeling dyes that span the full visible spectrum. These dyes have better labeling performances than the classic fluorescent labeling dyes such as Cy 3, Cy5, FITC and Texas Red
Super Fluor 680 SE (～Alexa Fluor 680 SE)
Super Fluor® dyes are the ideal substitute for Alexa Fluor dyes. Superfluor® dyes are a series of superior fluorescent labeling dyes that span the full visible spectrum. These dyes have better labeling performances than the classic fluorescent labeling dyes such as Cy 3, Cy5, FITC and Texas Red
