UV-method for the determination of Lactulose in milk and
foodstuffs containing dairy products

Principle:
(β-galactosidase)
(1) Lactulose + H2O → D-galactose + D-fructose
(glucose oxidase + catalase + H2O2)
(2) D-Glucose + H2O + O2 → D-gluconic acid + H2O2
(hexokinase)
(3) D-Fructose + ATP → F-6-P + ADP
(phosphoglucose isomerase)
(4) F-6-P → G-6-P
(glucose-6-phosphate dehydrogenase)
(5) G-6-P + NADP+ → gluconate-6-phosphate + NADPH + H+
(gluconate-6-phosphate dehydrogenase)
(6) Gluconate-6-phosphate + NADP+ → ribulose-5-phosphate + NADPH
+ CO2 + H+

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。

The CELLG3 assay reagent for the measurement of endo-cellulase (endo-1,4-β-glucanase) contains two components;

1) 4,6-O-benzylidene-2-chloro-4-nitrophenyl-β-D-cellotrioside (BCNPG3) and 2) thermostable β-glucosidase. The benzylidene blocking group prevents any hydrolytic action by the β-glucosidase on BCNPG3.  Incubation with an endo-cellulase generates a non-blocked colourimetric oligosaccharide that is rapidly hydrolysed by the ancillary β-glucosidase.  The rate of formation of 2-chloro-4-nitrophenol is therefore directly related to the hydrolysis of BCNPG3 by the endo-cellulase.  The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH 9.0).
Please note that a new assay kit (K-CELLG5) is now available for the measurement of endo-cellulase.  The CELLG5 reagent contains a cellopentaose core and exhibits vastly improved sensitivity for some cellulases.  In addition, the exchange of the benzylidene blocking group in CELLG3 for 3-keto-butylidene in CELLG5 improves the substrate’s water solubility significantly, allowing for a reduction in the concentration of DMSO required in the assay.  As DMSO is known to inhibit certain cellulases, this is another benefit in using CELLG5.  Megazyme now recommends the use of K-CELLG5 for all assays for the measurement of endo-cellulase.
Colourimetric method for the determination of 
endo
-1,4-β-glucanase (cellulase) in enzyme preparations and fermentationproducts
Principle:
(endo-1,4-β-glucanase)
(1) 3-Ketobutylidene-G5-β-PNP + H2O → Blocked-GX + G(5-X)-β-PNP
(thermostable β-glucosidase)
(2) G(5-X)-β-PNP + H2O → D-glucose + PNP
(alkaline solution)
(3) PNP → phenolate ion (yellow colour)
Note: PNP = 4-nitrophenol
