Mycobacterium avium

Description 

The ExcelDye™ 6× DNA Loading Dye (Orange) is pre-mixed buffer for tracking the DNA sample during the electrophoresis on agarose or polyacrylamide gels. It contains one dye (Orange G) for tracking the DNA migration. The Orange G migrates at approximately 30 bp on a standard 2% TAE agarose gel (50 bp on 1% TAE agarose gel). The included glycerol keeps the DNA at the bottom of the well and the presence of EDTA chelates divalent metal ions to prevent the process of metal-dependent nuclease.

Composition 

• 0.15% Orange G 
• 10 mM Tris-HCl (pH 8.0) 
• 60% glycerol 
• 60 mM EDTA

Storage 

4°C for 12 months
-20°C for 36 months

Overview

• Extract high quality & quantity total RNA including miRNA
• No phenol step required; isolate all RNA in one fraction
• Bind & elute all RNA irrespective of size or GC content, without bias
• Very sensitive & linear down to a few cells without the need for carrier RNA
• Isolate from a wide variety of specimens
• Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
• Available in a variety of formats to suit your needs
• Purification is based on spin column chromatography that uses Norgen’s resin separation matrix

Norgen’s Exosomal RNA Isolation Kit (for the extraction of RNA from EV’s that have been isolated using IZON’s qEV columns) constitutes an all-in-one system for the isolation of exosomal RNA from exosomes previously isolated using IZON’s qEV columns or concentrated using IZON’s EV Concentration kit. This kit allows for the isolation of RNA from intact extracellular vesicles (EVs) where the purification is based on spin column chromatography that employs Norgen’s proprietary resin.

The kit is designed to isolate all sizes of extracellular vesicle RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kit allows the user to elute into a flexible elution volume ranging from 50 μL to 100 μL. The purified RNA is of the highest integrity, and can be used in a number of downstream applications including real time PR, reverse transcription PCR, Nothern blotting, RNase protection and primer extension, and expression array assays.

Overview

• All-in-one solution for inclusion body protein isolation and purification
• Fast and convenient spin column protocol
• Complete kit with Cell Lysis Reagent, Inclusion Body Solubilization Reagent, buffers and spin columns to purify proteins
• Purification is based on spin column chromatography that uses Norgen’s resin separation matrix

These kits provide everything required to isolate and purify inclusion body proteins from induced bacterial cultures. First a proprietary Cell Lysis Reagent is used to selectively lyse the cells and release inclusion bodies in their solid form. Next, inclusion bodies are dissolved and their contents released using the provided IB Solubilization Reagent. Inclusion body proteins are then further purified using spin columns for rapid and convenient buffer exchange and desalting. This kit provides a convenient way to screen recombinants prior to scaling up.

ProteoSpin™ Inclusion Body Protein Isolation Micro Kit

The process is efficient and streamlined and can process up to 12 samples in only 60 minutes. Each spin column is able to recover up to 50 µg of acidic or basic proteins. Purified recombinant proteins are then ready for SDS-PAGE, 2D gels, Western blots, Mass Spectrometry analysis, and other applications.

ProteoSpin™ Inclusion Body Protein Isolation Maxi Kit

The procedure is efficient and streamlined and can process up to 4 samples in approximately 2 hours. Each spin column is able to recover up to 12 mg of acidic or basic proteins from 100 mL of induced bacterial culture. Purified recombinant proteins are then ready for SDS-PAGE, 2D gels, Western blots, Mass Spectrometry analysis, and other applications.

About Inclusion Bodies

Bacteria are widely used for the expression of different proteins. However, 70-80% of the proteins expressed in bacteria by recombinant techniques are typically contained in insoluble inclusion bodies (i.e., protein aggregates). The protein of interest found in these subcellular structures is often inactive, due to incorrect folding. The production rate of recombinant proteins stored in inclusion bodies is invariably higher than those synthesized as soluble proteins. The reason behind this is thought to be the resistance of insoluble proteins to proteolysis by cellular enzymes. In addition, separation of insoluble recombinant proteins in inclusion bodies is considerably easier than that of soluble proteins. These factors have been the major influences favoring scale-up of high-value proteins using bacterial fermentation for example. Procedures for the purification of the expressed proteins from inclusion bodies are often labour-intensive, time-consuming and not cost-effective. This kit provides the essential reagents for cell disruption, inclusion body solubilization and purification using spin column chromatography – all optimized to work together thereby simplifying the process and saving a tremendous amount of time and cost.

Storage Conditions

The Cell Lysis Reagent and IB Solubilization Reagent should be stored at 4°C upon receipt of this kit. All other solutions should be kept tightly sealed and stored at room temperature. This kit is stable for 2 years after the date of shipment. Once opened, the solutions should be stored at 4°C when not in use except for the pH Binding Buffers (Acidic and Basic). Some precipitation will occur with 4°C storage. This precipitation should be dissolved with slight heating to room temperature before using.
