DBCO-PEG2-NHS ester is a click chemistry PEG reagent containing NHS ester that is able to react specifically and efficiently with primary amines (e.g. the side chain of lysine residues or aminosilane-coated surfaces) at neutral or slightly basic condition to form a covalent bond. The hydrophilic PEG spacer arm improves water solubility and provides a long and flexible connection that minimizes steric hindrance involved with ligation. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Introduction
MagPure A3 utilizes Magen’s solid-phase paramagnetic bead technology for high-throughput purification of PCR amplicons. AmPure utilizes an optimized buffer to selectively bind PCR amplicons 100bp and larger to paramagnetic beads. Excess primes, nucleotides, salts and enzymes can be removed using a simple washing procedure. The resulting purified PCR product is essentially free of contaminants.

Principle
This product is based on the purification method of high binding magnetic particles. PCR amplicons mix with MagPure A3, 100bp and larger DNA binds to magnetic beads. Excessprimes, nucleotides, salts and enzymes can be removed using a simple washing procedure and finally DNA was eluted by Elution Buffer or Water.
Advantages
Wide application – DNA products, enzyme digestion system, PCR reaction
High recovery – suitable for 100bp-30kb fragments
High purity – effectively remove dNTP, primer, primer dimer, salt ion and other impurities
Strong applicability – manual operation or automatic workstation

Storage and Stability
MagPure A3 should be stored at 2-8°C upon arrival and is stable up to 18 months under the condition. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect its performance. Shake the reagent well before use. It should appear homogenous and consistent in color.DO NOT FREEZE.

Product Info
Overview
Columns bind proteins of interest while endotoxins flow through
Reduce endotoxin levels to less than 0.01 EU/µg of protein
Proteins are desalted
Greater than 95% protein recovery
Concentrate protein samples and remove detergents at the same time
Effectively remove a wide range of detergents including SDS, Triton® X-100, CHAPS, NP-40, and Tween 20
Purification is based on spin column chromatography that uses Norgen’s resin separation matrix
The ProteoSpin™ Total Protein Concentration, Detergent Clean-Up and Endotoxin Removal Kits are designed for the rapid removal of endotoxins from previously purified proteins or peptides, with protein recoveries of > 95% being achieved. Endotoxins, also known as lipopolysaccharides, are cell-membrane components of Gram-negative bacteria such as E. coli. Endotoxins liberated by Gram-negative bacteria are frequent contaminations of protein solutions derived from bioprocesses. Due to the high toxicity of endotoxins in vivo and in vitro, their removal from protein preparations is often necessary prior to the use of the protein in downstream applications. These kits efficiently reduce endotoxin levels to ≤ 0.01 EU/mg of protein, using spin column chromatography based on Norgen’s proprietary resin as the separation matrix. These kits are highly efficient in removing many different salts commonly used in the laboratory including, but not limited to, MgCl2, NaCl, KCl, CaCl2, LiCl and CsCl. The purified protein samples can be used in a number of downstream applications including sequencing, cloning, and in vitro and in vivo introduction into cells and organisms for various purposes. The simultaneous removal of salts while concentrating a dilute protein solution makes the kit a convenient method for preparing proteins before running many downstream applications such as SDS-PAGE, isoelectric focusing, X-ray crystallography, NMR spectroscopy, mass spectroscopy and other applications.
Mini Kit
The ProteoSpin™ Total Protein Concentration, Detergent Clean-Up and Endotoxin Removal Mini Kit is designed for the rapid removal of endotoxins from up to 200 μg of previously purified proteins or peptides, with protein recoveries of > 95% being achieved.
