Atto 647N是新一代红色光谱区荧光标签。该染料设计用于生命科学领域，如标记DNA、RNA或蛋白质等。该标签具有吸收性强、荧光量子产量高、光稳定性好、耐臭氧性好、溶解性好、三重形成少该标签具有吸收性强、荧光量子产率高、光稳定性好、耐臭氧性好、溶解性好、三重态形成少等特点。Atto 647N 是一种阳离子染料。偶联至底物后，染料携带+1的净电荷。 与大多数Atto标签一样，在典型应用中，吸收和荧光反应在2至11的pH值范围内是独立的。所提供的Atto 647N 由两种具有几乎相同吸收和荧光特性的异构体混合物组成。Atto-染料标记的磷脂 Sigma-Aldrich 提供了多种带有一个或两个脂肪酸基团（亲脂性基团）和一个磷酸酯残基（亲水基团）的甘油磷脂。它们标记在亲水性头基上。将磷脂掺入膜后，荧光团位于膜的水/脂质界面。我们目前提供1，2-二棕榈酰基-sn-甘油-3-磷酸乙醇胺（DPPE），1，2-二油酰基-sn-甘油-3-磷酸乙醇胺（DOPE），棕榈酰基-sn-甘油-磷酸乙醇胺（PPE）和，用Atto-染料标记的1，2-二肉豆蔻酰基-sn-甘油-3-磷酸-乙醇胺（DMPE）。在此查找更多信息 Atto 647N belongs to a new generation of fluorescent labels for the red spectral region. The dye is designed for application in the area of life science, e.g. labeling of DNA, RNA or proteins. Characteristic features of the label are strong absorption, excellent fluorescence quantum yield, high photostability, excellent ozone resistance, good solubility, and very little triplet formation. Atto 647N is a cationic dye. After coupling to a substrate the dye carries a net electrical charge of +1 . In common with most Atto-labels, absorption and fluorescence are independent of pH in the range of 2 to 11, used in typical applications. As supplied Atto 647N consists of a mixture of two isomers with practically identical absorption and fluorescence properties. Atto-Dye Labeled Phospholipids Sigma-Aldrich offers a variety of glycero-phospholipids carrying one or two fatty acid groups (lipophilic groups) and a phosphate ester residue (hydrophilic group). They are labeled at the hydrophilic head group. After incorporation of the phospholipid into a membrane the fluorophore is located at the water/lipid interface of the membrane. We currently provide 1,2-dipalmitoyl- sn -glycero-3-phosphoethanolamine (DPPE), 1,2-dioleoyl- sn -glycero-3-phosphoethanolamine (DOPE), palmitoyl- sn -glycero-phosphoethanolamine (PPE), and 1,2-dimyristoyl- sn -glycero-3-phospho-ethanolamine (DMPE) labeled with Atto-dyes. find more information here
