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.

Overview

• Convenient – With the ready-to-use Master Mix, the user needs only to add template to the master mix and enzyme in order to set up the reverse transcriptase reaction
• Time Savings – Set up RT reactions in a shorter time since less pipetting steps are required
• Cost Efficient – No need to buy separate enzymes, dNTPs and buffers. All are included with the ready-to-use Master Mix kits
• High Sensitivity and Yield – the optimized Master Mix allows for highly sensitive amplifications with high yields of PCR products
• Robust Enzyme – broad range of working temperatures from 37°C to 60°C. Capable of amplifying difficult templates with a high degree of reproducibility

TruScript Reverse Transcriptase is Available in Three Convenient Formats:

1. TruScript Reverse Transcriptase Kit (Cat.#54440)

This kit contains 5X RT Buffer and a vial of TruScript Enzyme Mix (200 units/µL). This enzyme can be used for reverse-transcription reactions with any user-supplied primers.

2. TruScript First Strand cDNA Synthesis Kit (Cat.#54420)

This is an all-in-one, ready-to-use product for simple set-up of reverse transcription of total RNA (both poly A- or non-poly A-containing transcripts).

The kit contains the 2x Reaction Mix and the TruScript Enzyme Mix. The 2x Reaction Mix contains a blend of buffer, nucleotides and primers (oligo dT and random hexamers) for effective cDNA synthesis from total RNA transcripts.

3. TruScript First Strand cDNA Synthesis Kit for mRNA (Cat.#54400)

This is an all-in-one, ready-to-use product for simple set-up of reverse transcription of messenger RNA (poly A-containing transcripts).

The kit contains the 2x Reaction Mix and the TruScript Enzyme Mix. The 2x Reaction Mix contains a blend of buffer, nucleotides and oligo dT primer for the effective cDNA synthesis from total RNA transcripts or enriched mRNA sample.

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.
