“At FARMOVS, we have the opportunity to work with the world’s top pharmaceutical companies, where we form part of the evaluation of labelled and/or conjugated antigens and antibodies that are developed for accurate quantification of endogenous and pharmaceutical compounds. Alternatively, commercially available kits and reagents are also used for the same purpose if the sponsor cannot supply the customised antigens/antibodies. The developed assay methods are put through a rigorous validation assessment to confirm the selectivity, sensitivity, and robustness of the assay,” says Anton Engelbrecht, FARMOVS Bioanalysis Specialist. 

FARMOVS, affiliated to the University of the Free State and operating from the Bloemfontein Campus, is a leading clinical research organisation (CRO) with a unique advantage. As the only on-site ISO15189-accredited and GLP-certified pharmacokinetic laboratory on the African continent, with numerous successful inspections by leading international regulators, it offers the highest quality bioanalytical services in a variety of biological matrices for the development of pharmaceutical products.

Engelbrecht says: “The team of bioanalytical experts thrives on the excitement generated by new discoveries that lead to better treatment of a variety of physiological diseases.”

Advanced technology backed by 47 years of bioanalytical experience

The clinical research organisation prides itself on advanced technology, backed by 47 years of bioanalytical experience. It has developed more than 580 validated analytical methods that adhere to the International Council for Harmonisation and the US Food and Drug Administration (FDA) guidelines. FARMOVS’ analytical methods have been used in more than 3 000 pre-clinical and clinical trials, contributing to the manufacturing of pharmaceutical drugs that are now used by households across the globe.

At FARMOVS, Engelbrecht says, it is a “world filled with novel methods of analysis and subsequent technological integration that expands the horizons of clinical research forming an important part of the discovery and production of new life-saving medicines that is constantly improving the quality of life of people all over the world”.

Engelbrecht says: “New technology and innovation should be the building blocks of any laboratory, and among these are the three fastest sample production members of our Immunochemistry Laboratory team – the STARLet pipettors.”

“We chose the Microlab® STARLet apparatus by Hamilton, because of its ability to perform sample analysis in large quantities at a greater speed by means of robotic pipetting and robotic automated microplate reading, which is a semi-automated process.”

He shared his excitement about improvements in the field of immunoassay development for the purposes of pharmaceutical analysis. This involves the preparation of unique immunoanalytical reagents, analysis of new categories of compounds, methodology, and instrumentation. The most important examples in this field are the continuous development of bead-based immunoassays.

Staying competitive in the industry

Immunoassay methods, such as radioimmunoassay (RIA) and enzyme immunoassay (EIA), among others, are also used at FARMOVS to analyse macromolecules for clients. “The RIA method is used for the determination of several pharmaceutically important compounds in biological fluids. RIA requires a sample containing the antigen of interest, a complementary antibody, and a radiolabelled version of the antigen. To increase the selectivity of an assay, all samples are pre-treated to eliminate high molecular weight endogenous matrix components, including anti-drug antibodies,” explains Engelbrecht.

Although FARMOVS has adequate technology to provide market-related results, the plan is to expand the team to include a multiplex platform that is a sensitive, fully automated immunoassay platform with multiplexing and custom assay capability. “This will pave the way to use an even more sensitive method to quantify biomarkers in the fields of oncology, neurology, cardiology, inflammation, and infectious disease. We aim to remain competitive in our industry, so naturally we must recruit the brightest and most evolved to join the team,” he says.

Prof Tredoux turns theories regarding the formation of metals on its head
2013-09-17

 

Prof Marian Tredoux
17 September 2013

The latest research conducted by Prof Marian Tredoux of the Department of Geology, in collaboration with her research assistant Bianca Kennedy and their colleagues in Germany, placed established theories regarding how minerals of the platinum-group of elements are formed, under close scrutiny.

The article on this research of which Prof Tredoux is a co-author – ‘Noble metal nanoclusters and nanoparticles precede mineral formation in magmatic sulphide melts’ – was published in Nature Communications on 6 September 2013. It is an online journal for research of the highest quality in the fields of biological, physical and chemical sciences.

This study found that atoms of platinum and arsenic create nanoclusters, long before the mineral sperrylite can crystallise. Thus, the platinum does not occur as a primary sulphur compound. The research was conducted at the Steinmann Institute of the University of Bonn, Germany, as well as here in Bloemfontein.

Monetary support from Inkaba yeAfrica – a German-South African multidisciplinary and intercultural Earth Science collaborative of the National Research Foundation (NRF) – made this research possible. Studies are now also being conducted on other metals in the precious metal group, specifically palladium, rhodium and ruthenium.

The discovery of the nanoclusters and the combination with arsenic can have far-reaching consequences for the platinum mine industry, if it can be utilised to recover a greater amount of platinum ore and therefore less wastage ending up in mine dumps. This will signify optimal mining of a scarce and valuable metal, one of South Africa’s most important export products.

For Prof Tredoux, the research results also prove thoughts she already had some twenty years ago around the forming of platinum minerals. “Researchers laughed in my face, but the evidence had to wait for the development of technology to prove it.” Young researchers were very excited at recent congresses about the findings, since the new models can bring new insights.

“Chemistry researchers have been talking about platinum element clusters in watery environments for quite a while, but it was thought that these would not appear in magmas (molten rock) due to the high temperatures (>1 000 degrees celsius).”

Prof Tredoux has already delivered lectures at congresses in Scotland, Hungary, Sweden and Italy on this research.
