Author:Pretorius, PJ; Linder, PWDate:1998The acid-base properties of hydrous ferric oxide were studied by glass electrode potentiometry. From the potentiometric data, surface protonation constants were derived according to the Diffuse Double Layer convention. Chemical equilibrium ...Read more
Author:Zawaira, A; Pooran, A; Barichievy, S; Chopera, DDate:Sep 2011A number of molecular biology techniques are available to generate variants from a particular start gene for eventual protein expression. The authors discuss the basic principles of these methods in a repertoire that may be used to achieve ...Read more
Author:Van Brummelen, AC; Becker, JVW; Mancama, Dalubuhle T; Hoppe, HCDate:Jan 2010The most important contributing factor to the current malaria crisis is the rapid spread of parasite resistance to available anti-malarial drugs. Anti-malarial drug resistance is critical and the need for compounds with novel modes of action ...Read more
Author:Van Brummelen, AC; Becker, JVW; Mancama, Dalubuhle T; Hoppe, HDate:Jan 2010In order to establish malaria parasite transfection technology in South Africa, firefly luciferase and green fluorescent protein (GFP) reporter constructs were prepared. In attempt to simplify these constructs, a var intron (PFC0005w), ...Read more
Author:Segobola, J; Adriaenssens, E; Tsekoa, Tsepo L; Rashamuse, Konanani; Cowan, DDate:Jan 2018The Kogelberg Biosphere Reserve in the Cape Floral Kingdom in South Africa is known for its unique plant biodiversity. The potential presence of unique microbial and viral biodiversity associated with this unique plant biodiversity led us to ...Read more
Author:Twala, BV; Sewell, BT; Jordaan, JDate:Jan 2010Immobilisation of enzymes is of considerable interest due to the advantages over soluble enzymes, including improved stability and recovery. Glucose Dehydrogenase (GDH) is an important biocatalytic enzyme due to is ability to recycle the ...Read more
Author:Govindasamy, K; Potgieter, S; Kumar, S; Land, K; Muzenda, EDate:Sep 2012Microfluidics has found widespread application in the fields of molecular biology, DNA analysis and most recently, point of care diagnostics. We present a paper based microfluidic device for rapid, in-the-field detection of pathogenic bacteria ...Read more
