產(chǎn)品描述
Cy5.5 (Cyanine 5.5) 是一種發(fā)近紅外(NIR)熒光的花青素?zé)晒馊玖?。它的消光系?shù)高,熒光也很亮,并且對(duì)pH不敏感,并且由于它的熒光波長(zhǎng)(Em:~700nm)恰好處于肌體組織近紅外窗口 I 的區(qū)域(肌體的血液,體液和組織此區(qū)域背景熒光弱,而長(zhǎng)波長(zhǎng)穿透性強(qiáng)),所以Cy5.5常應(yīng)用于小動(dòng)物活體體內(nèi)成像中。 Cy5.5可以用來(lái)標(biāo)記蛋白,抗體,多肽,納米粒等,它醉常見(jiàn)的使用是標(biāo)記核酸分子(DNA和RNA)。
