DBCO-PEG5-acid is an analog of DBCO-Acid with PEG linker and a DBCO group. DBCO group is a highly reactive cycloalkyne which is commonly used for copper-free Click Chemistry reactions. The hydrophilic PEG chain allows for increased water solubility of compounds in aqueous media. The terminal carboxylic acid can react with primary amine groups in the presence of activators (e.g. EDC, or HATU) to form a stable amide bond. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

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.

Norgen’s Streptococcus agalactiae TaqMan PCR Lyophilized Kit is designed for the detection of Streptococcus agalactiae specific DNA in a real-time PCR based on the use of TaqMan® technology. The lyophilized format is designed to ship the kit at ambient temperature.
Norgen’s Streptococcus agalactiae TaqMan Lyophilized Probe/Primer and Control Set is designed for the detection of Streptococcus agalactiae specific DNA in a real-time PCR based on the use of TaqMan® technology. The lyophilized format is designed to ship the kit at ambient temperature.
All kit components should be stored at -20°C upon arrival.
Once reconstituted, repeated thawing and freezing (>2 times) of the Master Mix and Positive Control should be avoided, as this may affect the performance of the assay. If the reagents are to be used only intermittently, they should be frozen in aliquots.
Each kit is provided with 4 tubes of 2X PCR Master Mix and each tube is enough to run 25 reactions. It is not necessary to reconstitute all Master Mix tubes at once. The Master Mix tubes can be reconstituted as and when needed.
All kit components can be stored for 2 years after the date of production without showing any reduction in performance.
