  1. 16. Characterization of Biomolecular Interactions Using a Multivariate Approach

    Författare :Karl Andersson; Mats Gustafsson; Jörgen Carlsson; Olav Kvalheim; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Biochemistry; Chemometrics; QSAR; Interaction; kinetics; Biokemi; Biochemistry; Biokemi;

    Sammanfattning : This thesis presents a novel bioinformatic methodology denoted the bio-chemometric approach. The methodology is designed for generation of detailed descriptions and predictions of biomolecular interactions. It is based on multivariate analysis of the sensitivity of a biomolecular interaction to multiple minor changes in the experimental conditions. LÄS MER
