Overview

• Simple protocol that is free of detergents
• Fast processing time
• Process a variety of inputs
• Compatible with mass spectrometry and NMR spectroscopy
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

This kit provides a fast and simple procedure for the isolation of total proteins from tissue, bacteria, yeast or mammalian cells without the use of SDS, Triton® X-100 and other detergents. Detergents are extensively used to prepare protein samples; however, these detergents have undesirable effects on downstream analysis. These effects include extraneous peaks in mass spectrometry, artifacts with chromatography and electrophoresis, interference with microinjection into cells and interference with protein immunization. 

The Detergent-Free Total Protein Isolation Kit maintains high protein recovery and yields proteins that are 100% detergent-free.  Purification is based on using Norgen’s proprietary resin together with Lysis Solution, followed by protein filtration using a filter column (provided). The purified proteins can be used in a number of downstream applications including mass spectrometry, SDS-PAGE, isoelectric focusing, NMR spectroscopy and more.

Each Lysis Tube is able to process up to 50 mg of tissue, 10¹⁰ bacterial cells, 10⁹ yeast cells or 10⁷ mammalian cells. Preparation time for 12 samples is less than 10 minutes.
