ProteoSpin™ Abundant Serum Protein Depletion Kit
Rapid and efficient removal of abundant proteins from serum and plasma samples
Process 10 samples in 30 minutes
Allows for visualization of low abundance proteins
Convenient and affordable spin column protocol
Generic protocol allows for depletion from human and other animal samples
Purification is based on spin column chromatography that uses Norgen’s resin separation matrix
This kit provides a fast and simple procedure for the effective depletion of major serum proteins including albumin, α-antitrypsin, transferrin and haptoglobin from serum and plasma samples. Such abundant proteins usually obscure less abundant proteins in gel electrophresis making them difficult to visualize and recover. The kit reduces sample complexity to allow for convenient investigation of less abundant proteins. In other applications such as mass spectroscopy, fractionating abundant proteins improves the resolution of less abundant proteins. The kit is 'generic' in that it is not antibody-based and can thus be used to deplete abundant proteins from any starting material - human or various other animals - making it more versatile, flexible and affordable than other kits. Resulting proteins are ready for a range of applications including 2D gel electrophoresis, SDS-PAGE, Mass Spectrometry, Protein microarrays, DIGE (Difference Gel Electrophoresis) and more.
Figure 1. Depletion of Abundant Proteins. Abundant proteins were depleted from human serum using the ProteoSpinTMAbundant Serum Protein Depletion Kit. Lane 1 represents the input human serum proteins, while Lanes 3 and 4 represent the elution after the abundant proteins were depleted with the kit. Lane 2 represents the binding flowthrough, and contains the proteins that have been depleted from the serum sample.
Figure 2. Depletion of Abundant Proteins. A 2D gel was run after the abundant serum proteins were depleted from human serum using the ProteoSpinTM Abundant Serum Protein Depletion Kit. The abundant proteins including albumin, a-antitrypsin, transferin and haptoglobin have been removed from the sample, allowing the visualization and detection of the lower abundance proteins of interest.
All solutions should be kept tightly sealed and stored at room temperature. Once opened, the solutions should be stored at 4°C. This kit is stable for 2 years after the date of shipment.
