一般描述
赫斯特 33258，也被称为双联苯亚胺，是一种蓝色荧光染料。它被归类为一种染色体染剂，可与DNA双螺旋的小沟结合，识别一组四对A-T碱基对。
应用
赫斯特 33258被用于荧光法估算样品中DNA浓度，这种方法比分光光度法更好，它可以测定纳克级DNA。并且，由于赫斯特 33258适用于识别细胞培养基中的支原体污染，由于其高荧光性。

Development of eye tissue is initiated by a conserved set of transcription factors termed retinal determination network (RDN). In the fruit fly Drosophila melanogaster, the zinc-finger transcription factor Glass acts directly downstream of the RDN to control identity of photoreceptor

In the current model of DNA SSBR, PARP1 is regarded as the sensor of single-strand breaks (SSBs). However, biochemical studies have implicated LIG3 as another possible SSB sensor. Using a laser micro-irradiation protocol that predominantly generates SSBs, we were able

Measuring the concentration of DNA using fluorometry is more sensitive than spectrophotometry, allowing the detection of nanogram quantities of DNA. In this assay, DNA preparations of known and unknown concentrations are incubated with the fluorochrome Hoechst 33258. Absorption values for
