AATOM(TM) 700 alkyne

Product key features: Ex/Em: 699/715 nm Extinction coefficient: 120,000 cm^(-1)M^(-1) Reactive group: alkyne Efficient Conjugation: Click chemistry labeling of azides on peptides, antibodies, and other biomolecules High Quantum Yield & Stability: Provides bright fluorescence with high photostability and thermal resilience Zwitterionic: Minimizes non-specific binding to biological surfaces, reducing background noise in live-cell imaging and super-resolution microscopy. Product description: AATOM(TM) 700 is a near-infrared fluorescent dye characterized by its strong absorption, high photo and thermal stability, and good aqueous solubility. It is optimally excited within the 670-715 nm wavelength range. As a zwitterionic compound, AATOM(TM) 700 remains electrically neutral when conjugated to biomolecules or other substrates. Its strong electron-accepting properties result in efficient fluorescence quenching by electron donors such as guanine and tryptophan. These properties make AATOM(TM) 700 ideal for precise applications including single-molecule detection and super-resolution microscopy techniques like PALM, dSTORM, and STED. Furthermore, AATOM(TM) 700 is compatible with flow cytometry (FACS), fluorescence in situ hybridization (FISH), and a variety of other biological assays, making it a versatile tool in advanced fluorescence-based research. The alkyne derivative of AATOM(TM) 700 is widely used for labeling azides on peptides, antibodies, and other biomolecules via click chemistry. It participates in copper-catalyzed azide-alkyne cycloaddition (CuAAC) with azide-containing molecules.
