PEG13-bis(Amino-Tri-(Propargyl-PEG2-ethoxymethyl)-methane) is large molecule with two sets of three terminal alkynes joined together by a large PEG linker. The alkynes are most frequently used in copper click chemistry with azides. The PEG linkers as well as numerous amide bonds provide high aqueous solubility to this compound, which may alter ADME of this compound.

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.
Maxi Kit
The ProteoSpin™ Total Protein Concentration, Detergent Clean-Up and Endotoxin Removal Maxi Kit is designed for the rapid removal of endotoxins from up to 4 mg of previously purified proteins or peptides, with protein recoveries of > 95% being achieved.

Sulfo DBCO-Amine can be used to derivatize carboxyl-containing molecules or activated esters (e.g. The NHS ester) with DBCO moiety through a stable amide bond. The low mass weight will add minimal spacer to modified molecules and the hydrophilic sulfonated spacer arm will greatly improve water solubility of DBCO derivatized molecules. DBCO is commonly used for copper-free Click Chemistry reactions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

This product is based on silica Column purification. The sample is lysed and digested with lysate and protease, DNA is released into the lysate. Transfer to an adsorption column. Nucleic acid is adsorbed on the membrane, while protein is not adsorbed and is removed with filtration. After washing proteins and other impurities, nucleic acid was finally eluted with low-salt buffer (10mm Tris, pH9.0, 0.5mm EDTA).

Storage and Stability
Proteinase K should be stored at 2–8°C upon arrival. However, short-term storage (up to 12 weeks) at room temperature (15–25°C) does not affect their performance. The remaining kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions. The entire kit can be stored at 2–8°C, but in this case buffers should be redissolved before use. Make sure that all buffers are at room temperature when used.
