VCell 6.1 released to beta site

October 25th, 2016|News, VCell Posts|

2016-10-14.  A new version of VCell (6.1) was released to beta site. The new version replaces VCell 6.0 in beta, and enhances the new Rule-Based Modeling capabilities available in VCell. Advantages of Rule-Based Modeling in VCell are

  • Specify rule-based models in a GUI, no scripting language required
  • Rule-based models can span multiple compartments
  • Reactions and rules can be mixed in one model
  • Full support for rules in all VCell Application types (spatial, nonspatial, deterministic, stochastic).
  • A set of rules can […]

New VCell Model from the Hille lab

June 9th, 2016|News, VCell Posts|

VCell models were used to quantitatively analyze FRET measurements were used to demonstrate that voltage-sensing phosphatases (VSPs) have catalytic activity for PIP3 (Keum et al. 2016.  Phosphoinositide 5- and 3-phosphatase activities of a voltage-sensing phosphatase in living cells show identical voltage dependence. Proc Natl Acad Sci U S A. 10.1073/pnas.1606472113, PMID 27222577).  Find the public VCell model here.
