The ProteoSpin™ Detergent Clean-Up Micro Kit removes detergents from protein samples while concentraing the sample at the same time. The kit employs a novel spin column technology that offers convenience, speed, and ease-of-use. The kit can remove trace amounts of detergents from protein samples while maintaining high protein recovery.  All types of detergents including ionic, non-ionic and zwitterionic detergents can be effeciently removed in a very short time, eliminating the need for for labourious procedures such as dialysis. The kit is designed to remove detergents in protein solutions either in their free form or bound form, as when complexed with the protein.  Also, unlike other commercially available kits that can only remove a single detergent and often do not remove denaturants, the ProteoSpin™ Detergent Clean-Up Micro Kit removes a variety of detergents and denturants that may be used during the purification of the protein sample while providing high protein recovery.

The kit employs a prorietary matrix to remove detergents from protein samples. Breifly, pH Binding Buffer is added to the protein sample and the sample is applied to Norgen's column (BIND).  Under these conditions the proteins will bind to the column while detergents and other contaminants are removed in the flowthrough.  The bound proteins are then washed to remove any remaining impurities (WASH).  Lastly, the clean proteins are eluted into a small volume of the provided Elution Buffer or into other optional elution buffers (user-provided) (ELUTE).  Please see the procedure flowchart to the right.

No further purification of the protein sample is required after detergent removal, and it can be used directly in a variety of downstream applications including  mass spectrometry, SDS-PAGE, isoelectric focusing, and NMR spectroscopy. This kit also offers the additional advantage of fractionating basic proteins from a protein solution, thereby allowing for additional purification of that basic proteins from other contaminating acidic proteins. 

FEATURES AND BENEFITS

• Remove  a variety of detergents - Detergents including SDS, Triton® X-100, CHAPS, NP-40, Triton® X-114 and Tween 20 can be removed using the kit.
• Effective detergent removal - Detergent removal of greater than 95% for many protein samples, allowing for detergent-sensitive tryptic digestion.  Can also remove detergents that are complexed with proteins.
• Complete kit - The ProteoSpin™ Total Protein Detergent Clean-Up Micro Kit contains all the solutions and columns for the processing of 25 total protein samples.  Each spin column is able to process 50 µg of either acidic or basic protein
• Fast and easy processing -  Preparation time for 12 samples is only 20 minutes.
• Eluted proteins can be used directly in downstream applications - No need for additional sample preparation procedures for downstream applications. Concentrate protein sample and remove detergents at the same time.
• No detergent carryover - Each sample is processed individually using its own spin column, resulting in no carryover or column bleed from sample to sample.
• Ready-to-use columns - No purging, swelling of resin, or lengthy activation steps required.
