麦芽β-葡聚糖酶/β-葡聚糖酶检测试剂盒 Malt β-Glucanase/Lichenase Assay Kit (MBG4 Method) 货号:K-MBG4 Megazyme试剂盒

麦芽β-葡聚糖酶/β-葡聚糖酶检测试剂盒

英文名:Malt β-Glucanase/Lichenase Assay Kit (MBG4 Method)

货号:K-MBG4

规格:100 assays (manual) / 400 assays (auto-analyser)

市场价: 4664

alt β-glucanase:                  
100 assays (manual format) / 400 assays (auto-analyser format)
Lichenase:                            
100 / 200 assays (manual format) / 330 assays (auto-analyser format)

The MBG4 reagent contains a single substrate, namely 4,6-O-benzylidene-2-chloro-4-nitrophenyl-β-(31-β-D-cellotriosyl-glucoside) (BCNPBG4). The benzylidene acetal group prevents any hydrolytic action by exo-acting hydrolytic enzymes such as β-glucosidase or cellobiohydrolase. Mixed linkage 
β-glucanase (endo-1,3:1,4-β-glucanase) / lichenase (EC 3.2.1.73) acts specifically to release 2-chloro-4-nitrophenol (CNP) from this substrate. The rate of release of CNP is directly related to the β-glucanase/lichenase activity in a sample. The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH = 10.0).

Note that the substrate is not hydrolysed by β-glucosidase or cellobiohydrolase. The substrate can be hydrolysed by certain endo-cellulases (e.g.Trichoderma sp.) but this does not result in an increase in absorbance.

过氧化氢酶检测试剂盒 Catalase Assay Kit 货号:K-CATAL Megazyme试剂盒

过氧化氢酶检测试剂盒

英文名:Catalase Assay Kit

货号:K-CATAL

规格:100 / 200 assays per kit

市场价: 4134

 Megazyme’s catalase assay kit provides a simple colourimetric method for the measurement of catalase activity. The method is delivered in a fast and reliable format and may be used to detect catalase activity in various samples, including food, biological and bacterial samples. The calculation method included allows for significant variation in the concentration of the H2O2 substrate solution that is employed in the assay which translates into a reduction in the ‘hands on’ time required by the analyst in comparison to other commercial kits.

Colourimetric method for the determination of catalase activity.

Principle:
          (catalase)
(1) 2H2O2 → H2O2 

                              (peroxidase)
(2) 2H2O2 + DHBS + AAP → quinoneimine + 4H2O
                                                  (purple colour)
Note: 
DHBS 
3,5-Dichloro-2-hydroxybenzenesulfonic acid
AAP = 4-aminoantipyrene

 

Kit size:                            100 / 200 assays
Method:                            Spectrophotometric at 520 nm
Total assay time:            20 min
Detection limit:                0.5 U/mL

乳糖检测试剂盒 Lactose Assay Kit 货号:K-LOLAC Megazyme试剂盒

乳糖检测试剂盒

英文名:Lactose Assay Kit

货号:K-LOLAC

规格:65 assays per kit

市场价: 5618

The K-LOLAC test kit offers a rapid, novel, sequential measurement of free-glucose and lactose in conventional, low-lactose and lactose-free dairy products. This sequential assay format reduces the manual input required by an analyst when compared to traditional lactose assay formats and therefore improves both accuracy and efficiency. When used in combination with the Megazyme Creep Calculator provided, the β-galactosidase employed in this kit allows for the selective measurement of lactose in the presence of galacto-oligosaccharides (GOS) which are commonly found in lactose-free dairy products. This constitutes a significant improvement over existing commercially available lactose assay kits which typically overestimate lactose content in lactose-free samples due to the unselective hydrolysis of GOS by β-galactosidase. Lastly, the sensitivity of the K-LOLAC assay kit has been doubled through the use of a cascade biochemical pathway, helping to significantly reduce the LOD and LOQ for the assay.
