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.

N-(t-Boc-Aminooxy-PEG2)-N-bis(PEG3-propargyl) is a branched crosslinker molecule with two terminal propargyl groups and a t-Boc protected aminooxy group. The propargyl groups can react with azide-bearing compounds or biomolecules via copper catalyzed azide-alkyne Click Chemistry to yield a stable triazole linkage. The protected amine can be deprotected under acidic conditions. Reagent grade, for research purpose. Please contact us for GMP-grade inquiries.

Fractionate leukocytes from whole blood in minutes with provided RBC Lysis Buffer
Isolate total RNA, including microRNA, without phenol
Rapid and convenient spin-column format and 96-well plate for high throughput applications
Purified RNA is ready for any downstream application including RT-PCR, qRT-PCR, NGS, arrays and more. Find out more information on Norgen’s NGS services
Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix
These kits provide a rapid method for the isolation and purification of total leukocyte (white blood cell) RNA from mammalian blood samples. These kits are supplied with an RBC (red blood cell) Lysis Buffer for selective removal of red blood cells and fractionation of leukocytes by centrifugation. Isolation of leukocyte RNA results in improved expression profiling and other downstream applications by removing the masking effects of some RNAs which are very abundant in whole blood, such as globin mRNAs. These kits are able to isolate total leukocyte RNA, including both large mRNA and all small RNA species containing microRNA (miRNA) and small silencing RNA (siRNA). The purified RNA is of the highest quality and can be used in a number of downstream applications.
Leukocyte RNA Purification Kit (Spin Column)
This kit provides a rapid method for the isolation and purification of total leukocyte RNA from mammalian blood samples in 40 minutes. Allowable blood input ranges from 10 μL to 2 mL or 3 x 106 Leukocytes
Leukocyte RNA Purification Plus Kit (Plus)
Norgen’s Leukocyte RNA Purification Plus Kit provides a rapid method for the isolation and purification of total leukocyte (white blood cell) RNA from up to 3 mL of mammalian blood samples. Complete 10 purifications in as little as 40 minutes.
Purification is based on 96-well column chromatography using Norgen’s proprietary resin as the separation matrix. Purification can be performed using either a vacuum manifold or centrifugation. Norgen’s kit allows for the isolation of total leukocyte RNA, including all small RNA species. The purified RNA is of the highest quality and can be used in a number of downstream applications including real time PCR, reverse transcription PCR, northern blotting, RNase protection and primer extension, and expression array assays. Allowable blood input ranges from 10 μL to 1 mL or 1.5 x 106 Leukocytes.
All solutions should be kept tightly sealed and stored at room temperature. The RBC Lysis Buffer should be stored at 4°C upon arrival. These reagents should remain stable for at least 1 year in their unopened containers.
