Lectures and textbooks can cover the theoretical aspects of protein purification and laboratory classes can teach the practical techniques, but there are other topics which are difficult to learn by conventional methods. In order to purify any protein you need to know which separation techniques are likely to be most effective under the circumstances and, probably more important, which techniques are not. This knowledge cannot be picked up by following a fixed recipe for a class practical. It requires some thought and usually comes with experience, generally during postgraduate research. This is the iPhone version of the award-winning program that has been widely used in schools, colleges and universities since 1983. Protein Purification's associated tutorial aims to guide you through a simulation of some of the more commonly-used protein separation techniques and to let you experiment with the simulation. It starts off by letting you examine how a simple mixture of proteins behaves during gel filtration and ion-exchange chromatography and then goes on to allow the design and testing of full purification protocols using more complex mixtures of proteins. It is assumed that you are familiar with the theoretical background to the most common separation techniques, enzyme assays etc. and that you understand the concept of the isoelectric point of proteins. The app will model failure as accurately as success - so be careful!
Version History The in-app upgrade has been removed. This is now the full version, ad-supported. 1.8.0 11/12/2014 Removed restriction on pooling fractions. Minor layout changes and bug fixes. 1.7.3 01/03/2014 Added support for iOS7. 1.7.0 09/12/2013 Bug fixes and layout enhancements. 1.6.0 08/29/2013 Bug fixes. 1.5.3 06/19/2013 The app now uses a file extension of .ppmixture for compatibility with the Mixture Editor. Existing files will be automatically updated. 1.5 01/24/2013 The simulation of ammonium sulfate fractionation has been rewritten based on the work of Kramer, J.M. et al., (2012) Biophysical Journal 102, 1907-1915. It now calculates the surface negative charge density to estimate the solubility of each protein. The simulation of hydrophobic interaction chromatography has also been rewritten. 1.4 12/11/2012 The simulation of ammonium sulfate fractionation has been rewritten based on the work of Kramer, J.M. et al., (2012) Biophysical Journal 102, 1907-1915. It now calculates the surface negative charge density to estimate the solubility of each protein. 1.3 12/06/2012 Fixed a bug that prevented the app giving exactly the same results as the online and iPad versions. Minor layout fixes. 1.2 11/19/2012 Compatibility with iOS 6 and the iPhone 5 1.1 09/24/2012 1.0 09/15/2012
