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.
Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
These kits provides a rapid method for the purification of total RNA from non-preserved saliva and nasal/throat swabs, and from preserved saliva collected on Norgen’s Saliva RNA Collection and Preservation Devices Dx (Cat. 53800) or preserved swabs collected in Norgen’s Total Nucleic Acid Preservative Tubes Dx (Cat. Dx69200). Purification is based on using Norgen’s proprietary resin separation matrix. RNA is preferentially purified from other cellular components such as proteins, without the use of phenol or chloroform. The chemistry employed in the kit allows the purification of total RNA, including viral and bacterial RNA, irrespective of size or GC content. The purified RNA is ideal for in vitro diagnostic use for medical purposes.
Saliva/Swab RNA Purification Kit Dx (Spin Column)
This kit is optimized to be used with any downstream application employing enzymatic amplification or other enzymatic modifications of RNA followed by signal detection or amplification. Any diagnostic results generated using the RNA isolated with Norgen’s Saliva / Swab RNA Purification Kit Dx in conjunction with an in vitro diagnostic assay should be interpreted with regard to other clinical or laboratory findings.
To minimize irregularities in diagnostic results, suitable controls for downstream applications should be used.
Norgen’s Saliva/Swab RNA Purification Kit Dx is intended for use by professional users such as technicians, physicians and biologists experienced and trained in molecular biological techniques.
Norgen’s Saliva/Swab RNA Purification Kit Dx does not provide a diagnostic result. It is the sole responsibility of the user to use and validate the kit in conjunction with a downstream in vitro diagnostic assay.
