General description

Atto 565 NHS ester is a commonly used amine-reactive reagent, provided by ATTO-TEC. It is widely used in protein labeling and readily reacts with compounds containing amino groups, forming a chemically stable amide bond between the dye, e.g., a protein. The optimum pH-range for NHS-ester coupling is pH 8.0 – 9.0. At this pH amino groups of proteins, i.e., the ε-amino groups of lysines are unprotonated to a degree sufficiently high for fast coupling.

Features and Benefits

  • Strong absorption
  • High fluorescence quantum yield
  • High thermal and photo-stability

Other Notes

Fluorescence of bioconjugates; employed in fluorescence resonance energy transfer, FRET, experiments.

How transcriptional bursting relates to gene regulation is a central question that has persisted for more than a decade. Here, we measure nascent transcriptional activity in early Drosophila embryos and characterize the variability in absolute activity levels across expression boundaries.

Single-cell quantitative studies of transcription have revealed that transcription occurs intermittently, in bursts. Although the
