NBD-F
CAS No. : 29270-56-2
MCE 国际站:NBD-F
产品活性:NBD-F (4-Fluoro-7-nitrobenzofurazan) 是一种用于氨基酸分析 (amino acid analysis) 的前荧光试剂。NBD-F 与一级或二级胺反应生成荧光产物,用于分析氨基酸和低分子量胺。
研究领域:Others
作用靶点:Fluorescent Dye
In Vitro: As the percentage of the organic phase changes, the retention time of NBD-F remains relatively stable, while the retention times of the derivatization products changes. The pH of the mobile phase affects the separation of the NBD-F and the derivatization products. NBD-F is a fluorescent derivatization reagent that is originally developed for amino acid analysis, and recently applied to the analysis of other amino acid derivatives such as N-methyl-D-aspartic acid and glutathione. The use of NBD-F appears to have several advantages in that the derivatization procedure is simple and its derivatives are highly stable.

指在大肠杆菌等细菌细胞中具有能和染色体分开进行独立复制的 F因子的雄性菌株。具有 F纤毛,通过与雌性菌株接合,可以高的频率进行 F因子的传递,同时也以低频率雄性菌的染色体向雌性菌传递。 F 菌株群体中有时有的细菌会失去 F因子而变为 F- 菌,但这种频率是很低的(约为 0.1%)。通过在含有适当浓度的吖啶色素的培养基中培养等方法,由于仅 F因子的复制受特异的抑制,所以可以很高的频率获得 F-菌株。
