Intrinsically Fluorescent Analogs - Xanthosine and Inosine Nucleotides |
|
|
|
|
|
|
|
Our compact, low molecular weight intrinsically fluorescent nucleotides combine fluorescence with close mimicry of the properties of natural nucleotides in respect of protein binding and interaction. They display environmentally sensitive fluorescence and therefore give strong signals upon a binding event which makes them perfect probes for stopped-flow and equilibrium analysis. The Mant-fluorophore is a commonly used FRET-probe in combination with Tryptophan or Tyrosin residues of the protein of interest.
