Q-PAGE™ Bis-Tris Precast Gel is a high-performance and easy to use precast polyacrylamide gel for electrophoresis in Bis-Tris buffer system (MOPS or MES). The optimized gel formula allows Q-PAGE™ Bis-Tris Precast Gel to show improved resolution, accurate results, and an extended shelf-life over conventional Laemmli Tris-HCl gels.
Q-PAGE™ Bis-Tris Precast Gels are available in gradient (4 to 12%) and fixed (8% and 12%) concentrations of polyacrylamide in 12-and 15-well formats. Two available cassette sizes, Mini (10 x 8.3 cm) and Midi (10 x 10 cm), are compatible with most popular protein electrophoresis systems. Q-PAGE™ Mini (QP2XXX) Gels are suitable for Bio-Rad® and other systems. Q-PAGE™ Midi (QP3XXX) Gels are suitable for Invitrogen® XCell SureLock® Mini-Cell, Invitrogen® Mini Gel Tank, Hoefer SE260, and other systems.

Introduction
HiPure FFPE Nucleic acid Kit supplies a simple and rapid DNA extraction for formalin-fixed, paraffin-embedded (FFPE) tissue and sections samples. This kit is based on silica gel column purification technology, no phenol-chloroform extraction or alcohol precipitation. The whole extraction only takes 20 minutes (not including digestion time). DNA can be directly used for downstream applications such as PCR, southern blot and viral DNA detection, etc.

Principle
Hipure FFPE Nuclear acid kit adopts silica gel column purification. The sample is deparaffinated by xylene and digested by lysate and protease. After de crosslinked at 90 ℃, DNA/RNA is released into the lysate. Adding ethanol to adjust the binding conditions, the sample is transferred to the column where DNA/RNA is adsorbed on the membrane and protein is removed without adsorption. Protein and other impurities are washed by buffer GW1, and the salt is removed by buffer GW2. Finally, the DNA / RNA is eluted by low salt buffer.
Advantages
Safety – deparaffinating without contacting with xylene or other toxic solution
Fast – without overnight incubation and digestion, several samples can be extracted within 2hours
High efficiency -remove the formaldehyde modification of DNA, greatly enhancing the sensitivity of PCR

Storage and Stability
Proteinase K should be stored at 2-8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15-25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2-8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.

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.
