Sulfo-Cyanine5.5 maleimide,水溶Cy5.5
产品介绍
Sulfo-Cyanine5.5 maleimide
Sulfo-Cyanine5.5 dye is a water soluble far red to NIR emitting dye which is very hydrophilic due to the presence of four sulfo groups. Sulfo-Cyanine5.5 derivatives exhibit high water solubility. The dye is a perfect choice for the labeling of sensitive proteins, nanoparticles, and highly hydrophylic biopolymers.
This maleimide is a thiol reactive dye that selectively labels cysteine residues. Disulfide bonds of native proteins should be reduced with an appropriate reducing agent, such as TCEP, according to our remended protocol.
