Amino Acid Analysis by High-Performance Liquid Chromatography after Derivatization with 1-Fluoro-2,4-Dinitrophenyl-5-L-Alanine Amide (Marfey's Rea

Precolumn derivatization of amino acids followed by their resolution by reverse-phase high-performance liquid chromatography (RP-HPLC) is now the preferred method for quantitative amino acid analysis. The derivatization step introduces

新型发光试剂ImmunoStar®Zeta的开发

前言 日本和光纯药株式会社于2009年正式将免疫印迹高灵敏度发光试剂ImmunoStar®LD（code NO.290-69904等）投放市场。这种试剂的发光底物，使用了鲁米的诺衍生物L-012（8-Amino-5-chloro-7-phenylpyrido [3,4-d ] pyridazine-1,4-（2H , 3H ） dione Sodium Salt）。L-012与鲁米诺相比，发光信号更强，性能更优异。然而，正因为ImmunoStar®LD与原有的免疫印迹用发光试剂相比
