3-甲基-8-（2′-脱氧-β-D-呋喃核糖基）异黄嘌呤

3-甲基-8-（2′-脱氧-β-D-呋喃呋喃糖基）异黄嘌呤蝶呤是一种高度荧光的鸟苷类似物，可以亚磷酰胺保护的二甲氧基三苯甲基形式，通过3’，5’特异性插入寡核苷酸中。 -磷酸二酯键合，使用自动DNA合成仪。

3-Methyl-8-(2′-deoxy-β-D-ribofuranosyl)isoxanthopterin is a highly fluorescent guanosine analogue, which in a dimethoxytrityl, phosphoramidite protected form, can be site-specifically inserted into oligonucleotides through a 3′, 5′-phosphodiester linkage using an automated DNA synthesizer.
