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.

Term of Validity: 14 months

Isothermal nucleic acid Principle Summary

The kit is based on rapid nucleic acid amplification technology at room temperature and constant temperature, its principle is that at room and constant temperature, the recombinase and primer form a protein/single-stranded nucleotide complex Rec/ssDNA, and invade the double-stranded DNA template with the help of auxiliary proteins and single-stranded binding protein SSB; then form a D-loop region at the invasion point and start to scan the DNA duplex, after finding the target region complementary to the primer and disintegration of the complex Rec/ssDNA, the polymerase also binds to the 3′ end of the primer to start the chain extension.

Isothermal nucleic acid Product Features

1/ High sensitivity and specificity, short reaction time.

2/ The reagent form is freeze-dried, stable and easy to operate.

3/ The reaction can be operated by metal bath and water bath pot without purchasing expensive PCR apparatus.
