“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.

Good quality wheat essential for bread production

“Wheat quality, specifically grain protein, is of the most crucial components determining the profitability of wheat farmers.”

This is according to Robbie Lindeque, wheat breeder at the ARC Small Grain Institute in Bethlehem. As a wheat breeder, one of his primary aims is to make a contribution to sustainable wheat production in the inland of South Africa.

A closer analysis of bread wheat protein

With his PHD thesis, "Protein quality versus quantity in South African commercial bread wheat cultivars”, Lindeque answered critical questions regarding the South African wheat industry. The major question of his PhD, which he received on 30 June 2016, was whether protein quality could compensate for protein quantity as a measure of bread quality in South Africa.

The three main wheat-producing areas in South Africa, the dryland summer rainfall region (Free State), dryland winter rainfall region (Western Cape), and the cooler irrigation regions (Northern Cape), were used as a starting point for the study.

Proteins are essential for the baking of good quality bread. Worldwide, the utilisation of wheat flour shipments in the baking industry is determined by the protein proportion of the shipment.

Lindeque says the aim of his thesis was to determine whether a closer analysis of bread wheat protein would provide a better indication of good or bad bread quality. “The conclusion from this study was that both protein quantity and protein quality from all three production areas in South Africa varies constantly in accuracy regarding the estimation of bread volume, mainly as a result of environmental factors,” says Lindeque.

Results relevant to the wheat industry

In 2012, application was made to the Winter Cereal Trust for funding of the project. After funding was approved – thus making the Winter Cereal Trust the main partner – seed samples were collected from the 2012 and 2013 national cultivar adaptation trials.

“After this, the seed underwent protein and flour analyses, which added a third year to the study, with the fourth year consisting of statistical processing and documenting of the results,” says Lindeque.

Funding by the Winter Cereals Trust contributed to the fact that the study constantly attempted to keep issues and results as relevant as possible to the wheat industry.
