Cyanine5 hydrazide|Cy5 hydrazide|Cy5酰肼   Cyanine5 hydrazide is a reactive dye for the labe生 of aldehydes and ketones, an analog of Cy5® hydrazide. This dye reacts smoothly and nearly quantitatively with various carbonyl groups encountered in biomolecules. Examples are proteins subjected to oxidative stress, glycosylated proteins pre-activated by periodate oxidation (including antobodies), and oligonucleotides with aldehyde moieties. Cyanine5 hydrazide replaces carbonyl-reactive Cy5®, Alexa Fluor 647, DyLight 649 dyes.                  Cyanine5 hydrazide|Cy5 hydrazide|Cy5酰肼   General properties： Appearance: dark blue powder Molecular weight: 569.61 Molecular formula: C32H42Cl2N4O Solubility: moderate solubility in water, good in polar organic solvents (DMF, DMSO, alcohols) Storage conditions: Storage: 24 months after receival at -20°C in the dark.
