DesertSci is pleased to announce that Proasis3, our widely used Protein Structure Database and Visualisation system, can now be run on the Apple iPad® with structure viewing using PyMol® (Schrödinger Inc). This latest development delivers the full functionality of Proasis3 to the iPad® and allows scientists the flexibility of a more mobile system. Developed at the request of our expanding community of users, we believe this will be a popular, additional platform for Proasis3.
