DBCO-C6-NHS ester is an amine-reactive compound, which can be used to modify an amine-containing molecule in organic media. This reagent isn’t soluble in aqueous media. The extended 6-carbon atom spacer arm improves solubility in commonly used organic solvents including dichloromethane, chloroform, THF, and ethyl acetate and it also improves derivatization efficiency and stability of conjugates. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.

SMOBIO’s B-BOX™ is a long wavelength, blue light LED epi-illuminator. It is compact in design and robust in structure. The B-BOX™ epi-illuminator provides an unprecedented level of safety for its user due to its non-UV light source and a low operating voltage of only 12 Volts, as well as its capability working with non-carcinogenic DNA/ protein dye. The B-BOX™ comes with high quality non-flickering LED light that is highly sensitive for DNA and protein dye. B-BOX™ can greatly ease the routine chore of gel extraction, enabling easy visualization and gel cutting even in bright ambient light. The multi-angle filter plate (Cat. No. VE0102) provides optimal angles for gel cutting, visualization, and documentation. The B-BOX™ also comes with amber colored filter goggles (Cat. No. VE0103) for gel cutting and visualization. The Phox™ Photobox (Cat. No. VE0104) provides a mini darkroom environment for images taken with any smartphone. Finally, a built-in barrier system around the working area helps facilitate cleaning.
