(accepted) The process of microarray oligo-target hybridization was modeled using equilibrium adsorption. The relationship between hybridization signal intensity and Gibbs free energy change for oligo-target duplex formation was our function of interest. The equilibrium adsorption model predicts S-shaped functional relationship between these two variables. We called the respective curve Energetic Hybridization Isotherm (EHI). It was demonstrated that change of target/probe ratio could result in shifts of the inflection point of S-shaped EHI curve along both axes. This study provides insights into EHI curves’ behavior observed in microarray experiments. |
