Atto 425-NHS ester

ATTO 425 NHS ester 是一种基于罗丹明 (Rhodamine) 结构 的 新型荧光标记物。具有强吸收、高荧光量子产率、高热稳定性和光化学稳定性，适合单分子检测和高分辨率显微镜。ATTO 425 NHS ester 是 ATTO 425 的 NHS 酯类衍生物，可标记蛋白或抗体。 应用： Atto 425 NHS 酯用于开发双功能荧光无机微粒（Zeolite L 晶体），设计用于靶向或成像多组分。与氨基或胺修饰的寡核苷酸反应形成稳定的胺键。用作分子信标的基本组份，旨在用于实时 PCR 分析，以快速、准确地鉴定革兰氏阴性细菌。当与苄基鸟嘌呤偶联时，Atto 425-NHS 的荧光被淬灭，但在标记 SNAP 标签融合蛋白后变为荧光，这使该偶联物成为活细胞实验的理想候选者。在三色 FRET 实验中用作供体探针之一，旨在研究 RNA-蛋白质复合物形成的动力学。 Atto 荧光标签专门为高灵敏度应用而设计，包括单分子检测。Atto 标签具有刚性结构，不显示任何顺式-反式-异构化。因此，这些标签具有超高强度，并且在共轭时具有最小的光谱偏移。 ATTO 425 NHS ester is a new fluorescent marker based on the Rhodamine structure. It has strong absorption, high fluorescence quantum yield, high thermal stability and photochemical stability, and is suitable for single molecule detection and high-resolution microscopy. ATTO 425 NHS ester is an NHS ester derivative of ATTO 425 that can be used to label proteins or antibodies. Application： Atto 425 NHS ester is used in the development of bifunctional fluorescent, inorganic micro-partices (Zeolite L crystals) designed for targeting or imaging mutliple components . Reacts with amino groups or amine modified oliognucleotides to form a stable amine bond. Utilized as an essential component of molecular beacons, which were designed for use in real-time PCR assays to allow for rapid and accurate identification of gram-negative bacteria . When conjugated with benzylguanine, the fluorescence of Atto 425-NHS is quenched but becomes fluorescent upon labeling of the SNAP-tag fusion protein, making this conjugate an ideal candidate for experiments in living cells . Used as one of the donor probes in three-color FRET experiments designed to investigate the kinetics of RNA-protein complex formation . Atto fluorescent labels are designed for high sensitivity applications, including single molecule detection. Atto labels have rigid structures that do not show any cis-trans-isomerization. Thus these labels display exceptional intensity with minimal spectral shift on conjugation.
