Cyanine7.5 hydrazide,酰肼近红外荧光染料
产品介绍
Cyanine7.5 hydrazide
A carbonyl-reactive hydrazide derivative of Cyanine7.5 near infrared (NIR) fluorophore. This dye has similar spectral properties with ICG (indocyanine green), but has a higher uantum yield of fluorescence. Hence, this fluorophore is ideal for in vivo imaging.
This is a carbonyl-reactive dye which is particularly useful for the labeling of antibodies after periodate oxidation. It also labels other carbonyl pounds (aldehydes and ketones), for example, many saccharides.
