D-乳酸检测试剂盒,D-Lactic Acid Assay Kit

D-乳酸检测试剂盒,D-Lactic Acid Assay Kit

名称:D-乳酸检测试剂盒
英文名:D-Lactic Acid Assay Kit
规格:50次
产地:爱尔兰
外观 :五玻璃瓶。
比重 :不适用
在水中的溶解度: 易溶
pH值: 7.0
气味: 无
粉末和液体形式
稳定性: 稳定 5年或以上(冷冻)

成分:
名称 比例
甘氨酰甘氨酸缓冲液 1瓶(玻璃)
烟酰胺腺嘌呤二核苷酸 1瓶(玻璃)
D-谷氨酸丙酮酸转氨酶 1瓶(玻璃)
D-乳酸脱氢酶酶 1瓶(玻璃)
D-乳酸的标准品 1瓶(玻璃)

许多食品和饮料中都发现有D-乳酸.  由乳酸菌产生, D-乳酸存在于牛奶的发酵产品中比如酸奶,腌菜,腌肉和腌鱼中。牛奶、肉、和果汁的质量可以通过测定D-乳酸的含量来确定。在葡萄酒生产中,D-乳酸的产生标志着酒被乳酸菌***。在化学工业中,D-乳酸和L-乳酸都是生产过程中聚合物的原料,比如聚交酯和一些生物学上可降解的聚合物。同时也应用在化妆品和医药品中。

原理:

D-乳酸的定量分析需要两步酶化反应。  第一个反应由D-乳酸脱氢酶(D-LDH)催化,D-乳酸在烟酰腺嘌呤二核苷酸(NAD+)的催化下,被氧化成丙***酸

然而, 因为反应(1)的移动和D-乳酸和NAD+有着密切的关系,下一步反应需要消耗掉产生的丙***酸 在大量D-谷氨酸的存在下,通过在D-谷氨酸-丙***酸转氨酶(D-GPT)的作用下把丙***酸转化为D-丙氨酸和2-***戊二酸。(2).

以上两个反应中产生的 NADH 的量可以用来计量D-乳酸的量。  NADH的量通过340nm处增加的吸光率来测量。

特异性,敏感度, 线性和准确性:

此方法特异性检测D-乳酸.

此方法特异性检测D-乳酸和L-乳酸。在D-乳酸锂(MW=96.0)的检测中,大约可以预期结果为96%(W/W),L-乳酸锂可以得到98%(W/W)。

检测的灵敏度为0.005 个吸光度单位。相当于样品最大体积为1.50 mL 时,样品浓度为0.107 mg/L(或者 1.60 mg/L ,样品体积0.1 mL) 。检测限为 0.214 mg/L,这是在0.010的吸光度差异,样品最大体积为1.50 mL为得到的 。

D-乳酸检测的线性变化为0.5 到 30 μg 。在重复测定中,同一份样品溶液,可能产生0.005 到 0.010 个吸光光度值的差异。这就相当于样品1.50 mL,样品溶液中D-乳酸的浓度为0.107 到 0.214 mg/L 。如果样品在制备阶段被稀释过,结果要乘以稀释倍数F。如果样品制备阶段,称量过样品,比如10 g/L,可能会产生0.02 到 0.05 g/100 g 的差异。

干扰:

如果D-乳酸的转换在实验指定的时间内(大约5分钟)彻底完成,通常认为是没有发生任何干扰。不过,这个也可以进一步验证,通过在实验的完成时,向比色皿中加入D-乳酸混合物(大约每0.1mL15ug),吸光光度值有会明显增加。

样品中的干扰物质的分析可以通过加入一个内参来确定。需要进行一个标准品定量回收实验,通过这个回收实验(也就是在最初的提取步骤中向样品中加入D-乳酸)可以算出样品在处理和提取过程中的损失量。
