CelGreen nucleic acid gel stain *10,000× concentrate in DMSO* is a fluorescent dye with a unique involvement that binds to all dsDNA double helix sulcus regions.In the free state, the side strand and CelGreen emit weak fluorescence, but the fluorescence is greatly enhanced once they are combined with the double-stranded DNA. Therefore, the fluorescence signal strength of CelGreen is related to the amount of double-stranded DNA, and the amount of double-stranded DNA in the PCR system can be detected according to the fluorescence signal.
Cy5.5 diacid is commonly used in biomolecular labeling, fluorescence imaging and other fluorescence biological analysis. Cy5.5 dyes and their derivatives are widely used to label polypeptides, proteins and nucleic acids.
N-methyl Mesoporphyrin IX 是广泛使用的 G-quadruplex DNA 特异性荧光结合剂,能有效监测 Aβ 纤颤。N-methyl Mesoporphyrin IX 对 G-四链体 DNA 敏感,对双链体、三链体和单链形式的 DNA 没有反应。N-methyl Mesoporphyrin IX 需通过与 Aβ 组装体堆叠才能发出强荧光。同时 N-methyl Mesoporphyrin IX 是一种原位抑制剂,是体外和细胞内 Aβ 淀粉样蛋白生成的非原位监测器。
