ATTO 678H
Like ATTO 643 and ATTO 647N, ATTO 678H 属于新一代长波长荧光标记物。该染料的特性包括吸收能力强、荧光量子产率高以及热稳定性和光化学稳定性高。 ATTO 678H is highly 亲水性 and highly water-soluble, and compared to ATTO 680, it exhibits significantly reduced aggregation behavior and a low tendency toward nonspecific binding. After coupling to a substrate, the dye is singly negatively charged. Unlike ATTO 680, it is not an electron acceptor; its fluorescence is not quenched by guanine, tryptophan, etc. Efficient fluorescence excitation occurs in the 665–695 nm range.
