一般說明

3-(2-吡啶基)-5,6-二(2-呋喃基)-1,2,4-三嗪-5′,5′′-二磺酸二钠盐也被称为Ferene,常用于测定水溶液中铁离子的浓度。该试剂对亚铁离子(Fe2+)反应灵敏,在还原剂存在的情况下与这些离子形成紫色复合物。形成的紫色的强度与溶液中铁离子的浓度成正比,并可以分光光度法定量测定。

應用

3-(2-吡啶基)-5,6-二(2-呋喃基)-1,2,4-三嗪-5′,5′′-二磺酸二钠盐已用作检测铁的灵敏比色测定法(ferene测定法)的成分。

A new method for specifically staining the iron atoms present in transferrin and lactoferrin after polyacrylamide gel electrophoresis and isoelectric focusing is described. The stain, 3-(2-pyridyl)-5,6-bis(2-(5-furylsulfonic acid))-1,2,4-triazine, disodium salt, or Ferene S, will detect transferrin in 5 microliters of human
