Amplite 荧光法葡萄糖-6-磷酸脱氢酶(G6PD)检测试剂盒是美国AAT Bioquest生产的用于检测葡萄糖的试剂盒,葡萄糖-6 - 磷酸脱氢酶( G6PD)催化葡萄糖-6 - 磷酸转化为6 - phosphoglucono -δ-内酯,所述和限速步骤中戊糖磷酸途径。这是至关重要的代谢途径,它提供通过维持辅酶烟酰胺腺嘌呤二核苷酸磷酸( NADPH)的水平降低了能量的细胞(如红细胞),以及用于生产戊糖。 NADPH的生产是非常重要的用于脂肪酸和/或类异戊二烯,如肝,乳腺,脂肪组织,和肾上腺生物合成的组织。该NADPH还保持谷胱甘肽在这些细胞的水平,有助于保护红血细胞免受氧化损伤。G6PD缺乏易患个人非免疫性溶血性贫血。 AAT Bioquest的Amplite 荧光葡萄糖-6 - 磷酸脱氢酶检测试剂盒提供了用于生物样品如血清,血浆,尿液,以及细胞培养样品中检测G6PD缺乏一种简单,灵敏,快速基于荧光的方法。在酶偶联测定法,比例是专门由一个荧光NADPH的传感器监测,以得到高的红色荧光产物的浓度。荧光信号可在EX/ EM = 540 nm/590 nm处读取荧光酶标仪。与G6PD检测试剂盒,我们能够探测到小至 1 mU/ml G6PD在100 μL的反应体积。百萤生物是AAT Bioquest的中国代理商,为您提供优质的Amplite 荧光法葡萄糖-6-磷酸脱氢酶(G6PD)检测试剂盒。

样品实验方案
简要概述
1.准备G6PD工作溶液(50 µL)
2.添加G6PD标准品或测试样品(50 µL)
3.在室温下孵育30分钟-2小时
4.监测Ex / Em = 540/590 nm时的荧光增加
溶液制备
1.储备溶液
所有未使用的储备溶液应分为一次性使用的等分试样,并在制备后储存在-20°C下。 避免重复冻融循环。
1.1 NADP储备溶液(100X):
在NADP小瓶(组分C)中加入100 µL H2O,制成100X NADP储备溶液。
1.2 G6PD标准溶液(100 U / mL):
将100 µL H2O或1X PBS缓冲液加到G6PD Standard(组分D)的小瓶中,制成100 U / mL G6PD标准溶液。
2.标准溶液
G6PD标准
将10 µL G6PD标准溶液添加到990 µL 1X PBS缓冲液中,以生成1000 mU / mL G6PD标准溶液。 将15 µL的1000 mU / mL G6PD标准溶液加入到485 uL的1X PBS缓冲液中以生成30 mU / mL的G6PD(G6PD7),然后进行1:3的系列稀释以获得G6PD标准品的系列稀释(G6PD6- G6PD1)。 注意:稀释的G6PD标准溶液不稳定,应在4小时内使用。
3.工作溶液
将5 mL测定缓冲液(组分B)加入一瓶酶探针(组分A)中。 将50 µL NADP储备溶液(100X)加入组分A的瓶子中,并充分混合。 注意:此G6PD分析工作溶液足以用于一个96孔板。
样品操作及实验分析
表1.黑色96孔微孔板中G6PD标准品和测试样品的布局。 G6PD = D-葡萄糖-6-磷酸脱氢酶标准品(G6PD1- G6PD7,0.04至30 mU / mL); BL =空白对照; TS =测试样品
BL | BL | TS | TS |
G6PD1 | G6PD1 | ... | ... |
G6PD2 | G6PD2 | ... | ... |
G6PD3 | G6PD3 | ||
G6PD4 | G6PD4 | ||
G6PD5 | G6PD5 | ||
G6PD6 | G6PD6 | ||
G6PD7 | G6PD7 |
表2.每个孔的试剂组成
孔 | 容积 | 试剂 |
G6PD1-G6PD7 | 50ul | 连续稀释(0.04至30 mU / mL) |
BL | 50ul | 稀释缓冲液(PBS) |
TS | 50ul | 测试样品 |
1.根据表1和表2提供的布局,准备G6PD标准品(G6PD),空白对照(BL)和测试样品(TS)。对于384孔板,每孔使用25 µL试剂代替50 µL。
2.向G6PD标准品,空白对照和测试样品的每个孔中添加50 µL G6PD工作溶液,以使总测定体积为100 µL /孔。 对于384孔板,请向每个孔中添加25 µL工作溶液,总体积为50 µL /孔。
3.避光保存,室温下孵育反应30分钟至2小时。
4.用荧光板读数器在Ex / Em = 540/590 nm处监测荧光增加,在570 nm处截止。
