DBCO-C2-PEG4-amine is a PEG linker which contains DBCO and amine moieties. The DBCO group is commonly used in copper-free Click Chemistry reactions. The amine group is reactive with carboxylic acids, activated NHS esters, carbonyls (ketone, aldehyde) etc. The hydrophilic PEG spacer increases solubility in aqueous media. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Product Info
The Flex caddy allows the Thermocycler GEN2 to be installed on the Opentrons Flex deck and sit below the deck, enabling below-deck cable routing and labware placed on top of modules to remain closer to the deck surface. The calibration adapter is used to calibrate the location of the Thermocycler. Caddies and calibration adapters are specific to the type of module.
Note: This item does not include the Thermocycler Module. The module is available with or without the Flex Caddy and Calibration tool: Thermocycler Module GEN2

DNase activity in a convenient and sensitive lateral flow colormetric assay that delivers results in real time. Great for Quality Testing for DNase contamination of materials and supplies.
Attogene’s DNaseAlarm Lateral Flow test is designed for the sensitive and accurate analysis of DNAse activity in liquid samples. DNase Alarm uses a synthetic DNA substrate that attaches to the streptavidin colloidal reporter molecule (gold) using a 5’ biotin. The DNA substrate also contains a FAM molecule that enables it to be captured by the anti-FAM antibody (test line). In the absence of DNases, the DNA oligo tethers gold to the test line giving a visual test line. When DNases are present, the DNA substrate is degraded, and the gold particles can no longer be tethered to the test line thus, signal is lost. Since the cleavage of the DNA Substrate increases over time when DNase activity is present, results can be evaluated kinetically. This assay has applications for quality control testing and analysis of unit activities of DNase and DNase inhibitors. DNase’s can cause havoc in laboratories working with DNA and are important to perform routine testing.
This test can be used to rapidly and efficiently detect DNase’s in both liquid and on solid surfaces and a perfect tool for monitoring manufacturing.

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.
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.
