T4 DNA Ligase is an ATP and Mg2+ dependent dsDNA ligase which catalyses the formation of a phosphodiester bond between 3’-hydroxyl and 5’-phosphate termini in duplex DNA, duplex RNA and some DNA/RNA hybrids. T4 DNA Ligase is active on both blunt-end and cohesive-end substrates. It is also completely inactivated by incubating at 70°C for 10 minutes.
This is a high-quality (commercial grade) version of the T4 DNA Ligase. T4 DNA Ligase is recombinantly produced in E. coli. ArcticZymes’ T4 DNA Ligase is extensively tested for contaminating DNase and RNase activities as well as residual host-cell gDNA.

The D-Glucosamine test kit is a high purity reagent for the measurement and analysis of D-glucosamine in neutraceutical/food products. This kit can also be used to measure N-Acetyl-D-Glucosamine and D-Glucosamine sulphate.
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.
