2-Aminopurine, a fluorescent analog of guanosine and adenosine, is a widely used fluorescence-decay-based probe of DNA structure. 2-Aminopurine has been used to probe nucleic acid structure and dynamics. 2-Aminopurine has been used to inhibit eukaryotic initiation factor-2α (eIF2α)-phosphorylation of osteoarthritis (OA) chondrocytes. 2-Aminopurine (2AP) is an analog of guanosine and adenosine, which can base pair with cytosine and thymine. It is used as a fluorescent probe in nucleic acid structure and dynamics. 2-Aminopurine (2-AP) inhibits double-stranded RNA-dependent protein kinase, protein kinase R (PKR).

| 7-Aminoactinomycin D
7-aminoactinomycin D (7-aad) can bind to DNA, and the maximum excitation/emission wavelength is 546nm/647 nm. The best excitation laser is 561nm or 488nm. It gives red fluorescence and is often used to observe the nucleus and nucleic acid. Store in freezer (-5 to -30°C) away from light. The solvent was DMSO. *The compound is unstable in solutions, freshly prepared is recommended |
