Propargyl-PEG4-acid is a PEG reagent with an alkyne and a terminal carboxylic acid. The carboxylic acid reacts with primary amine groups with the help of activators (e.g. EDC, or HATU). The 4-unit PEG spacer increases hydrophilicity. The alkyne can participate in copper-catalyzed Click Chemistry. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction
The HiPure FastFilter Plasmid DNA Maxi Kits combine the power of HiPure technology with the time-tested consistency of alkaline-SDS lysis of bacterial cells to deliver high-quality DNA. HiPure DNA columns facilitate the binding, washing and elution steps thus enabling multiple samples to be simultaneously processed. This system also includes a special filter cartridge which replaces the centrifugation step following alkaline lysis. Plasmid DNA purified by this system is suitable for automated fluorescent DNA sequencing, restriction endonuclease digestion, transfection of mammalian cells, and other manipulations. Up to 1000 µg high copy number plasmid DNA or 50-500 µg low copy number plasmid DNA can be purified from 200mL overnight culture.

Principle
The HiPure Plasmid procedure is based on alkaline lysis of bacterial cells followed by adsorption of DNA onto silica in the presence of high salt. The unique silica membrane used in the kit completely replaces glass or silica slurries for plasmid DNA minipreps. The procedure consists of 3 basic steps: Preparation and clearing of a bacterial lysate by alkaline method,then transfer the supernatant to column to bind DNA. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).
Advantages
High purity – purified plasmid can be directly used in sequencing, enzyme digestion and PCR, etc.
Fast – it takes only 15-60 minutes to complete the isolation
Economy – high cost performance

Storage and Stability
The kit components can be stored dry at room temperature (15-25°C) and are stable for at least 18 months under these conditions. If any precipitates form in the buffers, warm at 37℃ to dissolve. After addition of RNase A,Buffer P1 is stable for 6 months when stored at 2-8°C.

Attogene’s Montmorillonite Bentonite Clay binds toxins with high affinity and high capacity. Montmorillonite has been shown to be the active ingredient in bentonites. The proposed mechanism of action of Attogene’s Montmorillonite Bentonite Clay is through the adsorption of toxins (mainly onto the interlayer spaces of montmorillonite). Attogene’s Montmorillonite Bentonite Clay is a common anti-caking agent in animal feeds to adsorb aflatoxins and diminish their bioavailability. Its composite for application in drug system can be formed through the utilization of anionic, cationic, and nonionic surfactants.
Bentonite is a promising rock of clay which is found in nature. It is a major source of montmorillonite in nature. It is a rock produced of highly colloidal and plastic clays mainly comprised of montmorillonite. In addition to montmorillonite, bentonite may compose of some amount of crystalline quarz, cristobalite, and feldspar. Montmorillonite nanoclay is used as a drug carrier system and as an additive. Its composite for application in drug system can be formed through the utilization of anionic, cationic, and nonionic surfactants. These are used to improve basal spacing resulting in organo clay to be utilised in drug loading and drug release.

The ExcelTaq™ 5X Fluorescent PCR Master Mix is a ready-to-use mixture for amplifying targeted DNA fragments. It is designed to serve as a master mix for virtually all PCR applications. This product is supplied as a 5X concentrated mixture containing all the essential ingredients for PCR with the exception of templates and primers. In addition, the mixture contains electrophoresis tracking dye (Bromophenol blue) and a safer fluorescent DNA staining dye, which enables the user to track the electrophoresis process in real time as well as eliminates the need for the staining process. The resultant PCR reaction mixture is sufficiently dense enough to be loaded directly into a TAE or TBE buffered gel for electrophoresis.
