产品描述
MCLA,又称为6-(4-Methoxyphenyl)-2-methyl-3,7-dihydroimidazo[1,2-a]pyrazin-3(7H)-one hydrochloride,能够与超氧化物阴离子(O2–)或单线态氧(1O2)反应产生化学发光。MCLA与超氧化物可逆反应形成一加合物,该加合物的不可逆衰变产生冷光(~465nm),此反应表观速率常数是~105M–1s–1。MCLA化学发光是灵敏的超氧化物检测手段,最显著的应用是白细胞功能研究。

使用方法(For reference only)
– Prepare reaction buffer: 5 µM MCLA + buffer
Buffer examples:
for Cytochrome C: 50 mM Tris-Cl, pH 7.8, 0.1 mM EDTA, 7 mM sodium succinate .
for mitochondria proteins: 125 mM KCl, 10 mM HEPES, 5 mM MgCl2, 2 mM K2HPO4
– Conduct reaction in 100 µl of reaction buffer – Light emission is detected and quantified using a microplate luminometer with opaque (white) 96-well plates. The photomultiplier can be set to default with an integration time of 1000 ms. The MCLA signal is quantified as an integral of 20 s to 60 s of continuous measurement. – A positive control can be prepared with the xanthine/xanthine oxidase system: 1 mM xanthine + 0.1 unit/ml xanthine oxidase causes a ~100-fold increase in chemiluminescent signal as compared with xanthine or xanthine oxidase alone, which did not differ significantly from reaction buffer alone. Addition of SOD (CuZn-SOD from erythrocytes) decreases the MCLA signal by over 98%.
注意事项
为了您的安全和健康,请穿实验服并戴一次性手套操作。
