一般說明
1-氟-2,4-二硝基苯(DNFB)是修饰蛋白和多肽N端氨基酸的试剂。DNFB通常也称为桑格(Sanger′s)试剂,以Frederick Sanger的名字命名,他在1945年的一篇经典的论文中报道了使用DNFB对蛋白和多肽的N末端进行特异性衍生的过程。
應用
1-氟-2,4-二硝基苯用于诱发小鼠严重接触性超敏反应,通过体内成像方法,检测基因表达和诱发慢性瘙痒,用作分析搔痒行为的模型。
生化/生理作用
1-氟-2,4-二硝基苯是一种接触过敏性半抗原,通常用于实验研究接触超敏反应,诱发瘙痒模型和特应性皮炎。肥大细胞激活是DNFB诱发过敏的关键步骤。DNFB和蛋白质N端氨基酸共价连接,可用于桑格(Sanger )测序。
