產(chǎn)品簡介:
磺化Cy7.5(sulfo Cyanine 7.5; sulfo Cy7.5)是一種發(fā)近紅外(NIR)熒光的花青素類熒光染料。磺化Cy7.5是磺化修飾過的Cy7.5,水溶性好。磺化Cy7.5的消光系數(shù)高,熒光也很亮,并且對pH不敏感,并且由于它的熒光波長(Em:797nm)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,而長波長穿透性強(qiáng)),所以磺化Cy7.5常應(yīng)用于小動物活體體內(nèi)成像中。磺化Cy7.5可以用來標(biāo)記蛋白,抗體,多肽,核酸分子,納米粒等。由于強(qiáng)水溶性加帶電荷,磺化花青素標(biāo)記的生物分子更穩(wěn)定,不易產(chǎn)生疏水性聚集。
本產(chǎn)品磺化Cy7.5熒光基(fluorophore)是優(yōu)化后的結(jié)構(gòu),多次甲基(polymethine)橋鏈經(jīng)環(huán)己烯固化,熒光***產(chǎn)率提高了20%,從而使熒光更亮。
馬來酰亞胺(maleimide)是生物標(biāo)記反應(yīng)中常用的基團(tuán),它可以和巰基(-SH)通過親和加成反應(yīng)生成穩(wěn)定的巰醚(thioester)結(jié)構(gòu)從而實(shí)現(xiàn)標(biāo)記。盡管胺基(比如賴氨酸精氨酸側(cè)鏈)也有親和性,但在中性或微酸性緩沖液中,馬來酰亞胺選擇性標(biāo)記巰基(反應(yīng)速度比胺基快>1000倍)。標(biāo)記反應(yīng)反應(yīng)迅速,選擇性高,產(chǎn)率好,另外,巰基是一種在生物分子中***存在的官能團(tuán),比如蛋白中的絲氨酸(cysteine)和雙硫鍵等,因此馬來酰亞胺/巰基(maleimide/thiol)標(biāo)記已成為僅次于NHS/胺基標(biāo)記的***常用生物連接反應(yīng)(bioconjugation)。
磺化Cy7.5-馬來酰亞胺的水溶性非常好,所以可以在水相的標(biāo)記反應(yīng)體系中直接使用,不需要有機(jī)溶劑助溶,特別適合標(biāo)記對有機(jī)溶劑敏感的生物分子。另外磺化Cy7.5水溶性好,并且染料分子本身帶電荷,標(biāo)記后不會引發(fā)目標(biāo)分子疏水性聚集,提高熒光標(biāo)記產(chǎn)物的穩(wěn)定性?;腔疌y7.5-伯胺也溶于甲醇,DMSO,DMF等有機(jī)溶劑,標(biāo)記反應(yīng)也可以在純有機(jī)溶劑中進(jìn)行。如需脂溶性Cy7.5染料,可選擇普通花青(cyanine),即Cy7.5-馬來酰亞胺( D10039 )。
磺化Cy7.5-馬來酰亞胺標(biāo)記后的產(chǎn)物Ex/Em是788/808nm。和它具有相似熒光特性的染料包括Alexa Fluor 790,DyLight 800,吲哚菁綠(indocyanine green, ICG)等。
