产品详情
2-Di-1-ASP (DASPI; Compound 18a) 是一种单苯乙烯基染料,广泛用作双链 DNA 的线粒体染色和凹槽结合荧光探针。2-Di-1-ASP 对 G-四链体 (G4) 和双链 DNA 具有选择性。
生物活性
2-Di-1-ASP (DASPI; Compound 18a) is a mono-stryryl dye, and widely used as mitochondrial stain and groove-binding fluorescent probes for double-stranded DNA. 2-Di-1-ASP is selective for G-quadruplex (G4) and double-stranded DNA.

体外研究(In Vitro)
2-Di-1-ASP (Compound 18a) displays significant fluorescence enhancements in the presence of G-quadruplex (G4) structures (up to 300-fold), and good selectivity with respect to double-stranded DNA. 2-Di-1-ASP shows fluorimetric selectivity for parallel G4-DNA forms ( c-kit2 , c-kit87up , c-myc ). has not independently confirmed the accuracy of these methods. They are for reference only.
