Theses: Doctorates and Masters
This study included a series of experiments focussed on comparing extraction protocols for metabolomics-based analysis of Lewis rat polycystic kidney (LPK) tissue samples and healthy Lewis rat tissue samples. Firstly, the optimal sample loading (mass of tissue) was investigated. Based on previous studies, the appropriate mass to test was approximately 5 mg. Three different volumes of tissue extract equivalent to 1, 2.5 and 5mg of pooled healthy kidney tissue and pooled polycystic kidney tissue were trialled to see how they differed in terms of the number of reproducible, uniquely identified peaks captured after metabolite extraction, derivatisation and gas chromatography-mass spectrometry …
