(glucose oxidase)
(1) D-Glucose + H2O + O2 → D-glucono-δ-lactone + H2O2
(peroxidase)
(2) 2H2O2 + p-hydroxybenzoic acid + 4-aminoantipyrine →
quinoneimine + 4H2O

淀粉总量HK检测试剂盒
英文名： Total Starch HK Assay Kit
货号：K-TSHK
规格：100 assays per kit
A modification of AOAC Method 996.11 AACC Method 76-13.01 RACI Standard Method for the measurement and analysis of total starch in cereal flours and food products. This kit contains an improved α-amylase that allows the amylase incubations to be performed at pH 5.0 (as well as pH 7.0). The method has been further modified by adjusting the D-glucose determination to a hexokinase/glucose-6-phosphate dehydrogenase/NADP+ based format.
UV-method for the determination of Total Starch in grains,
animal feeds, foodstuffs and other materials
Principle:
(α-amylase, 100°C + DMSO)
(1) Starch granules + H2O → maltodextrins
(amyloglucosidase)
(2) Maltodextrins + H2O → D-glucose
(hexokinase)
(3) D-Glucose + ATP → G-6-P + ADP
(glucose-6-phosphate dehydrogenase)
(4) G-6-P + NADP+ → gluconate-6-phosphate + NADPH + H+
Kit size: 100 assays
Method: Spectrophotometric at 340 nm
Total assay time: ~ 90 min
Detection limit: 1-100% of sample weight
Application examples:
Cereal flours, food products and other materials
Method recognition:
AOAC (Method 996.11), AACC (Method 76-13.01), ICC (Standard
Method No. 168), and RACI (Standard Method)

Molecular Weight: 416.4
Purity: > 95%
High purity 1,4-β-D-Xylotriitol for use in research, biochemical enzyme assays and in vitro diagnostic analysis. This compound can be used as a substrate for xylan degrading enzymes such as endo-1,4-β-xylanase or β-xylosidase. Borohydride reduced oligosaccharides can be used in the place of native oligosaccharides when performing enzymatic degradation experiments using reducing sugar assays. The native oligosaccharides cannot be used for this purpose because, being reducing sugars themselves, they generate a large ‘blank’ value in these assays.
