Cy5 fluorophore emits strong near infrared fluorescent light upon excited at 650 nm while amine can react with a variety of amine reactive groups such as succinimidyl NHS ester, aldehyde, etc. Reaction between amine and other groups allows the labeling and conjugation of Cy5 PEG to the surface of proteins, antibodies or particles. PEG linker between Cy5 dye and amine offers better water solubility, flexible linker structure and enhanced stability. Compared to other common fluorescent dyes. Handling and Use: CY5-PEG-NH2  is sensitive to light and temperature. For best use, material should always be kept in low temperature in dry condition. Protect from light.  Avoid frequent thaw and freezing. For more information about using this product, .   Storage Conditions： CY5-PEG-NH2 should be stored at -20℃. Desiccate. Protect from light. Materials may be handled under inert gas for best stability.     Related Products: BIOTIN-PEG-NH2, DSPE-PEG-NH2 NH2-PEG-SH ,FA-PEG-NH2 FITC-PEG-NH2,RB-PEG-NH2 This product is for research use only and is not intended for use in humans or for diagnostic use.
