You Are Here uses your phone's GPS to show where you are on any map - Park or campus information boards, leaflets or even sketches.
Just take a picture of a map while you're out and about, or copy and paste one from the internet, then go to the place that the map shows. When you know where you are on the map, tap and hold to add a marker. Move around until you find another place on the map, and tap and hold to add a second marker. Your position will show on the map, updated as you move around.
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.
Protein Purification is the latest version of the award-winning program which has been widely used in schools, colleges and universities since 1983. It 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 simulation models failure as accurately as success - so you need to be careful!
Standalone webapp versions of Protein Purification are available for Windows 2000/XP/Vista/7 and OS X Snow Leopard, Lion and Mountain Lion. A free online version is also available for desktops and laptops.
An editor for the mixture files used by the Protein Purification simulation.
Mixtures can be created, edited and deleted. In each mixture, individual proteins can be created, imported, edited or deleted. Multisubunit proteins can be created by merging proteins.
Data can also be imported from online protein databases. Currently, import from RefSeq and UniProtKB are supported.
Files produced by the Mixture Editor can be used immediately by the Android version of the Protein Purification simulation app (the phone version must be upgraded). They can also be exchanged with the iPhone/iPad version of the Protein Purification simulation app via iTunes File Sharing.
Mixture Editor can import mixture files from email messages, Dropbox, etc.
