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.

Introduction

This product supplies a simple and rapid extraction of total RNA including microRNA from Blood, buffy coat, bone marrow, Cell suspension and other body fluids. The kit is based on superparamagnetic particles purification technology, no phenol-chloroform extraction or alcohol precipitation. Purified RNA is ready for downstream applications such as RT-PCR, virus RNA testing and so on.

Details

Principle

The Kit can be used for both manual extraction process and automatic nucleic acid extraction machines. This Kits is suitable for extracting RNA from ≤ 1 x10⁶ cells suspension, 50 μl Whole Blood, 50μl buffy coat, 20μl bone marrow. This product is based on the purification method of high binding magnetic particles. The sample is lysed and digested under the action of lysate and Protease. RNA/DNA is released into the lysate. After adding magnetic particles and binding solution, DNA/RNA will be adsorbed on the surface of magnetic particles, and impurities such as proteins will be removed without adsorption. The adsorbed particles were digested using DNase and washed with washing buffer to remove proteins and impurities, washed with ethanol to remove salts, and

Storage and Stability

MagPure RNA Particles and Proteinase K should be stored at 2–8°C upon arrival. DNase I should be stored at -20°C. However, short-term storage (DNase I up to 1 weeks, MagPure RNA Particles and Proteinase K up to 8 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 atleast 18 months under these conditions.
