Lumiprobe Corporation是美国一家高品质生物技术公司，专业提供分子生物学研究用的活性荧光染料。从2006年起，公司开始生产并销售生命科学研究和诊断学应用的优质化学药品。主要产品有：活性染料（ReactiveDye）和SYBRGreen I染料，定制合成荧光双标记引物。产品主要应用：点击化学（CLickChemistry）、蛋白质组学研究中的双向荧光差异凝胶电泳（2DDIGE）和实时荧光定量PCR（ReaLtimePCR）。Lumiprobe是通过ISO 9001认证的生命科学应用标准和定制试剂制造商。

荧光染料又称为荧光探针, 因具备检测速度快、重复性好、用样量少、无辐射等优点，成为大家广泛使用的荧光标示剂。同时也是细胞生物学等科学研究中不可或缺的重要工具，利用荧光探针可测定RNA和DNA的结构、研究DNA碱基损伤修复、辨别蛋白质分子中氨基的状态和蛋白质分子的活性区, 检测pmol级的蛋白质 ,区分不同构象的核酸以及有关药物的化学反应活性。荧光免疫分析采用时间-分辨技术可用于许多蛋白质、激素、病毒抗原及DNA杂交体的分析。激光诱导荧光光谱在活细胞、活体体液、DNA碱基序列和细菌原体的鉴定、恶性肿瘤的早期诊断和治疗中起到了重要的作用。

由于大多数荧光染料不具备选择性，被固载在生物活性载体的荧光染料，可利用生物活性物质之间的选择性（抗原抗体，生物素链霉亲和素），或者通过染料分子用适当的修饰官能团，通过官能团之间的相互反应，实现对目标物质的靶向性标记，下面我们就来给大家介绍常见的几类活性荧光染料：

活性荧光素及其衍生物广泛用于共价标记生物分子，例如抗体，碳水化合物，核酸，蛋白质，肽和寡核苷酸。各活化官能团对应的反应基团如下：

Sulfo-Cyanine3 is a sulfated derivative of Cyanine3 dye, well soluble in water because of two negatively charged sulfo groups in its structure. By its spectral characteristics, this yellow-orange fluorescent dye is an analog of Cy™3.

Hydrazides efficiently react with aldehydes and ketones resulting in hydrazones, so this compound can be used for conjugation with carbonyl derivatives of biomolecules.

The reaction runs in aqueous conditions, which is important when working with antibodies and proteins. Cys-diol groups in sugars in glycosylated proteins and antibodies can be oxidized into dialdehydes, and cysteine in proteins can be converted with enzymes to formyl glycerol (i. e. reactive groups for conjugation with Sulfo-Cyanine3 hydrazide). Carboxyl groups of aspartic and glutamic acids in proteins and peptides can be also conjugated with Sulfo-Cyanine3 hydrazide in the presence of activating agents: carbodiimide (EDAC) or methyl morpholine (DMTMM) derivatives.

Sulfo-Cy3 是 Cy3 染料的硫酸化衍生物，由于其结构中有两个带负电荷的磺基，因此可很好地溶于水。根据其光谱特性，这种橙黄色荧光染料是 Cy™3 的类似物。

酰肼有效地与醛和酮反应生成腙，因此该化合物可用于与生物分子的羰基衍生物缀合。

反应在水性条件下进行，这在处理抗体和蛋白质时很重要。糖基化蛋白质和抗体中的糖中的 Cys-二醇基团可被氧化成二醛，蛋白质中的半胱氨酸可被酶转化为甲酰基甘油（即与磺基花青 3 酰肼结合的反应基团）。蛋白质和肽中的天冬氨酸和谷氨酸的羧基也可以在活化剂存在的情况下与磺基花青 3 酰肼结合：碳二亚胺 (EDAC) 或甲基吗啉 (DMTMM) 衍生物。
