Summary
Software
1) Intrinsic Noise Analyzer (iNA) is an open source software for studying reaction kinetics in living cells. The software analyzes mathematical models of intracellular reaction kinetics such as gene expression, regulatory networks or signaling pathways to quantify concentration fluctuations due to the random nature of chemical reactions. iNA implements stochastic simulation, deterministic rate equation, and system size expansion methods such as Linear Noise Approximation and Effective Mesoscopic Rate Equations.
