ATTO 647 is rhodamine-based fluorescent label for the red spectral region that has similar spectral properties to Cy5. It has strong absorption, high fluorescence quantum yield, high thermal and photostability, and its absorption and fluorescence are independent of pH from 2 to 11. ATTO 647 is suitable for single-molecule detection applications, high-resolution microscopy (such as SIM, STED), flow cytometry (FACS) and fluorescence in-situ hybridization (FISH). ATTO 647N NHS ester is used for labeling amino-containing molecules such as proteins, peptides and amino-modified oligonucleotides.
An NHS ester allows the functionalization of an amino moiety in a variety of molecules, including DNA and RNA oligonucleotides, as well as peptides or proteins. NHS esters are especially useful in situations where the equivalent phosphoramidites exhibit instability to the conditions of oligonucleotide synthesis and/or deprotection.
ATTO 647是一種基于羅丹明的熒光標(biāo)記,用于紅色光譜區(qū),具有與Cy5類似的光譜特性。它具有強(qiáng)吸收、高熒光量子產(chǎn)率、高熱穩(wěn)定性和光穩(wěn)定性,其吸收和熒光與pH值從2到11無(wú)關(guān)。ATTO 646適用于單分子檢測(cè)應(yīng)用、高分辨率顯微鏡(如SIM、STED),流式細(xì)胞術(shù)(FACS)和熒光原位雜交(FISH)。ATTO 647N NHS酯用于標(biāo)記含氨基分子,如蛋白質(zhì)、肽和氨基修飾的寡核苷酸。
NHS酯允許多種分子中的氨基部分功能化,包括DNA和RNA寡核苷酸,以及肽或蛋白質(zhì)。NHS酯在等效磷酰胺對(duì)寡核苷酸合成和/或脫保護(hù)條件表現(xiàn)出不穩(wěn)定性的情況下特別有用。
