Perylene is a bright and extremely photostable fluorescent polycyclic aromatic hydrocarbon (PAH) label with a quantum yield approaching quantitative. Due to the low lifetime of fluorescence, this probe does not form excimers.
With this phosphoramidite, perylene can be introduced into DNA by automated oligonucleotide synthesis. Perylene is attached to the 5′ position of deoxyuridine (dU) through a triple bond and the fluorophore is electronically coupled to the deoxyuridine base. This coupling of dU and perylene makes the fluorescence sensitive to the base pairing of the dU portion of the molecule, allowing the discrimination between perfect and one base mismatched targets.
This amidite requires no special handling, coupling, or deprotection conditions. Recommended diluent is acetonitrile.
Perylene 是一种明亮且极耐光的荧光多环芳烃 (PAH) 标记，其量子产率接近定量。 由于荧光的低寿命，该探针不会形成准分子。
使用这种亚磷酰胺，可以通过自动寡核苷酸合成将苝引入 DNA。 苝通过三键连接到脱氧尿苷 (dU) 的 5′ 位置，并且荧光团与脱氧尿苷碱基电子耦合。 dU 和苝的这种偶联使荧光对分子的 dU 部分的碱基配对敏感，从而可以区分完美和一个碱基错配的靶标。
这种亚酰胺不需要特殊的处理、偶联或脱保护条件。 推荐的稀释剂是乙腈。
