Cellulase Activity Assay Kit.

The CellG5 assay reagent for the measurement of endo-cellulase (endo-1,4-β-glucanase) contains two components; 1) 4,6-O-(3-Ketobutylidene)-4-nitrophenyl-β-D-cellopentaoside (BPNPG5) and 2) thermostable β-glucosidase. The ketone blocking group prevents any hydrolytic action by the β-glucosidase on BPNPG5.  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 4-nitrophenol is therefore directly related to the hydrolysis of BPNPG5 by the endo-cellulase. The reaction is terminated and the phenolate colour is developed on addition of Tris buffer solution (pH 9.0).

The CellG5 assay represents a huge step forward in the methodology for the measurement of cellulase that traditionally relied on substrates such as CM-cellulose, Avicel, cellooligosaccharides, filter paper or dyed polysaccharides including CMC Congo red or cellulose azure.

Volcano3G® RT-PCR Probe 2x Master Mix contains all components required for general RT-qPCR
– optimized reaction mix for sensitive and reliable results
– engineered, truly thermostable Taq DNA polymerases with reverse transcriptase activity
– fast start function due to a hotstart aptamer formulation which prevents unspecific amplification at lower temperatures (<57°C)
– Pipetting aid in form of a blue dye for better visibility during aliquoting into well-plates
– included lysis function*

* = A sample extraction and sample lysis is not necessary as immediate hot PCR cycling conditions can brake cell- and virus membranes. Please see our published references to this product.

Note: Volcano3G® RT-PCR Probe 2x Master Mix is a unique master mix. If you are using it for the first time, we recommend to design primers to have higher melting/annealing temperatures (above 65°C). Additionally, for assay setup it is advised to perform RT-PCR test reactions with temperature gradients (i.e., for the annealing and extension steps) to identify the most proficient PCR protocol for your needs using our Volcano DNA polymerase products.

For research use and further manufacturing.

In case you are aiming to use our RUO products as components or for your development of e.g. an IVD medical device, please contact us.
