Principle:
                        (5-methylphenazinium methosulphate)
(1) L-Ascorbic acid + R-H2 + MTT → dehydroascorbate +                                                                                         MTT-formazan + H+
                            (ascorbic acid oxidase)
(2) L-Ascorbic acid + ½O2 → dehydroascorbate + H2O

Lumiprobe荧光素的替代染料–菁染料

Lumiprobe荧光素的替代染料–菁染料

知识背景:

菁染料是性能优良的可代替荧光素的染料,摩尔吸光系数高,其琥珀酰亚胺酯是最常用的脂肪氨基标记试剂,广泛用于蛋白、抗体、核酸及其他生物分子的标记和检测。通过改变次甲基链的长度, 可改变其荧光发射波长,每增加一个双键,按照Huoffman 规则正好红移约100nm。

菁染料Cy3 和Cy5 已成为基因芯片的首选荧光标记物; 另外,Cy5, Cy5.5 和Cy7 的吸收在近红外区背景非常低,是荧光强度最高、最稳定的长波长染料。特别适合于活体小动物体内成像代替放射性元素。

但由于菁染料, 尤其是不对称菁染料的合成副反应多, 副产物极性相近, 产物的分离提纯相当困难。菁染料特别是水溶性菁染料分子极性大, 分离提纯越加困难。

应用领域:

 广泛应用于多肽,蛋白,核苷酸及其他生物分子的标记和检测。
