FITC labeled polyamino acid---poly (L-lysine HBr salt) FITC

Fluorescamine labeled amino acids

The foreign trade name of Fluorescamine is Fluram, and its chemical name is 4-phenylspiro [furan-2 (3H), 1-dihydroisobenzofuran] -3,3-dione. It is a newly developed fluorescent labeling reagent in recent years, which can determine picomoles (pmol, i.e. 10-12 mol) of primary amines and is suitable for in vitro diagnostic determination of amino acids, peptides, and other primary amines. Fluorescamine (I) reacts with primary amine (II) to produce strong fluorescent substances. Under mild conditions, it reacts with amino acids or peptides to form stable fluorescent complexes. Can be used for fluorescence determination experiments of amino acids and enzyme hydrolyzed proteins.

荧光胺(Fluorescamine)标记氨基酸

荧光胺(Fluorescamine)的外商品名为弗路兰(Fluram),其化学名为4-苯基螺[呋喃-2(3H),1-二氢异苯并呋喃]-3,3-二酮,是近年来新发展的荧光标记试剂,可以测定微微摩尔(pmol即10~(12)mol)的伯胺,可适用于体外诊断测定氨基酸,肽,和其他伯胺,荧光胺(I)与伯胺(Ⅱ)反应后生成的强荧光物质。在温和条件下与氨基酸或者多肽中的氨基反应形成稳定的发荧光的复合物。可用于氨基酸、及酶水解蛋白的荧光测定试验。
