Guanosines labeled with free Amino groups (-NH₂)

Amine labeled nucleotides are widely used for attachment of labels through amine-reactive groups such as:

• dyes / fluorescent probes → Probes & Epigenetics used in
  
  • immunochemistry
  • DNA labeling by PCR or Nick Translation → Probes & Epigenetics
  • fluorescence in situ hybridization (FISH)
  • quantitative real-time PCR → Molecular Biology
  • signal transduction studies
  • cell tracing
  • receptor labeling
  • fluorescent analog cytochemistry
• stationary phases for affinity chromatography or pull-down studies
• proteins and peptides
• nucleic acids and oligonucleotides
• PNAs
