一般描述
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。
应用
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。
