產(chǎn)品介紹

Cyanine5.5 maleimide

Cyanine5.5 maleimide is a thiol reactive dye which is capable of selective labeling of sulfhydryl groups in proteins, an analog of Cy5.5® maleimide.

Near infrared emission of Cyanine5.5 makes this dye suitable for bioimaging applications.

Cyanine5.5 can replace Cy5.5®, Alexa Fluor 680, and DyLight 680.
