OG 488炔(也称为俄勒冈州绿色® 488炔或2 '，7'-二氟羧基荧光素炔，6-异构体)是一种明亮的绿色荧光炔激活探针，常规用于含叠氮化物生物分子的成像。OG 488炔通过铜催化点击反应(CuAAC)与叠氮化物反应，形成稳定的三唑连接基。二氟羧基荧光素具有更高的光稳定性，并且在比荧光素(pKa 6.5)更低的pH(pKa 4.8)下电离，这使得其即使在常规荧光素几乎不发荧光的微酸性pH下也发荧光。OG 488染料的吸收和发射实际上与广泛使用的荧光素染料相同。

OG 488 Alkyne, (also known as Oregon Green® 488 Alkyne or 2',7'-Difluorocarboxyfluorescein Alkyne, 6-isomer) is a bright, green-fluorescent alkyne-activated probe routinely used for imaging of azide-containing biomolecules. OG 488 Alkyne reacts with azides via a copper-catalyzed click reaction (CuAAC) to form a stable triazole linker.The fluorinated carboxyfluoresceins have higher photostability and ionize at a lower pH (pKa 4.8) than fluorescein (pKa 6.5), which makes them superior fluorescent dyes for use as reporter molecules in biological systems. The absorption and emission of OG 488 dye are virtually identical to widely used fluorescein dyes. The combination of higher photostability, lower pKa, and excitation ideally suited to the 488 nm laser line makes OG 488 dye an ideal replacement for the widely used fluorescein dyes.Oregon Green® is a registered trademark of Thermo Fisher Scientific.
