  2. Determination of a robust metabolic barcoding model for chemotaxonomy in Aizoaceae species : expanding morphological and genetic understanding by Hilgart, Amelia

    Published 2016
    “…Many studies have found that by comparing the vast metabolic fingerprints of closely related species to each other, secondary metabolites tend to be unique to the samples of individual species and are identified in clustering algorithms as the variables responsible for species-specific clustering. …”

  6. Development and preliminary evaluation of a diagnostic assay for neurosyphilis using a reverse transscription-polymerase chain reaction approach by Sindle, Jinny Charmaine

    Published 2025
    “…E. coli JM109 harbouring a positive control plasmid was used to spike CSF clinical samples. The sensitivity of the RT-PCR reaction using T. pallidum RNA was optimised and the assay could detect 101 T. pallidum equivalents of RNA The optimal quantity of the positive control was determined to be 5 x 10 3 E. coli positive control cells, and 15 μI of eluted RNA was used in the RT-PCR reactions. …”
