詳細(xì)介紹
熒光染料Cyanine7 alkyne,1954687-62-7供應(yīng),Cy7 ALK
Alkyne derivative of Cyanine7, a near infrared fluorophore, analog of Cy7?. The alkyne can be conjugated to a variety of azides via copper-catalyzed Click chemistry.
The dye has limited solubility in water, but it can be successfully conjugated in aqueous buffers with the addition of DMSO or DMF.
