Lumiprobe Corporation是美國一家高品質(zhì)生物技術(shù)公司,專業(yè)提供分子生物學(xué)研究用的活性熒光染料。從2006年開始,公司生產(chǎn)并銷售生命科學(xué)研究和診斷學(xué)應(yīng)用的化學(xué)藥品。產(chǎn)品主要有:活性染料(Reactive Dye)和SYBR Green I 染料,用于寡核苷酸合成的亞磷酰胺,點擊化學(xué)用染料和其它試劑。 產(chǎn)品主要應(yīng)用:點擊化學(xué)(Click Chemistry)、蛋白質(zhì)組學(xué)研究中的雙向熒光差異凝膠電泳(2D DIGE)和實時熒光定量PCR(Realtime PCR)。
作為Lumiprobe*代理,上海仁邦醫(yī)藥生物可提供Lumiprobe的完整產(chǎn)品線,滿足您的各種科研實驗需求。產(chǎn)品包括:羧酸類染料、羰基類染料,標(biāo)記分子氨基活性染料,標(biāo)記分子巰基活性染料,動物活體成像用染料,蛋白質(zhì)、多肽、核酸等生物分子標(biāo)記染料、點擊化學(xué)等。渠道正規(guī)(市場上部分是分裝,質(zhì)量不能保證),質(zhì)量保證,價格競爭力,而且我們的貨期僅需要3-5工作日,不需要像其他家攢單貨期3-4周。
磺化和非磺化染料都可用于標(biāo)記生物分子例如DNA和蛋白質(zhì)。染料之間的差異是它們的溶解性:磺基染料是水溶性的,并且它們不使用有機(jī)共溶劑用于在水性環(huán)境中的標(biāo)記。它們不易于在水中聚集。
There are two varieties of cyanine dyes: non-sulfonated cyanines, and sulfonated cyanines. For many applications they are interchangeable, because their spectral properties are nearly identical. Both sulfonated and non-sulfonated dyes can be used for the labeling of biomolecules such as DNA and proteins. The difference between the dyes is their solubility: sulfo- dyes are water-soluble, and they do not use of organic co-solvent for the labeling in aqueous environment. They are less prone to aggregation in water.
