Aminooxy-PEG3-propargyl has a alkyne group and an aminooxy group. The aminooxy group reacts with aldehydes or ketones to form a stable oxime linkages. The alkyne group can participate in copper catalyzed azide-alkyne Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries. Aminooxy compounds are very reactive and sensitive; they cannot be stored for long term. Immediate use (within 1 week) is highly recommended.

Overview

• Isolate all sizes of exosomal and extracellular vesicle RNA, including microRNA
• ​Bind and elute all RNA irrespective of size or GC content, without bias
• No phenol extractions
• No Proteinase K treatment
• No carrier RNA
• Concentrate isolated RNA into a flexible elution volume ranging from 50 µL to 100 µL
• Purify high-quality RNA in 15-20 minutes
• Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin

This kit provides a fast, reliable and convenient method to isolate and concentrate exosomal RNA from previously purified exosomes. It allows for the isolation of RNA from intact extracellular vesicles (EVs) purified from different urine or plasma/serum sample volumes. The purification is based on Norgen’s proprietary resin.

The Exosomal RNA Isolation Kit is designed to isolate all sizes of RNA, including microRNA. 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 PCR, reverse transcription PCR, Northern 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. 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 Binding Buffer C and Binding Buffer N. Some precipitation will occur with 4°C storage. This precipitation should be dissolved with slight heating to room temperature before using.
