“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.

In future, stargazers and astronomers will look at the Scorpius constellation near the Milky Way with new eyes. Earlier this year, a group of international astronomers announced the discovery of an exotic binary star system, AR Scorpii. The system is in the Scorpius constellation.

Prof Pieter Meintjes, researcher in the Department of Physics at the University of the Free State (UFS), worked with four colleagues on what he describes as a “wonderful discovery”. This sensational discovery, which could lead to the production of cleaner energy on Earth, will be published in the research journal, Nature, early in 2017.

Model developed to interpret new set of measurements
The exotic binary star which was discovered consists of a red dwarf and a white dwarf revolving around each other every 3,5 hours. The binary system showed very prominent pulsations of 117 and 118 seconds respectively. The pulsations can be explained by a bundle radiation produced by the white dwarf star.

“These new observations have shown that the radiation is strongly polarised, a sign that we are dealing with synchrotron radiation here. Synchrotron radiation is produced by electrons accelerated to extremely high energy levels in the magnetic field of the white dwarf star,” says Prof Meintjes.

He developed a theoretical model to interpret a new set of measurements that was taken by the 1,9 m telescope and the 10 m SALT telescope at the South African Astronomical Observatory (SAA0).

Totally unique phenomenon could contribute to energy production on Earth
“I further indicated that the interaction between the magnetic fields of the white dwarf star and the red dwarf star induces secondary processes that specifically describe the behaviour of the radiation in the radio band and infrared band accurately. AR Sco is the first white-red dwarf binary system of which all the pulsated radiation could be explained by the synchrotron process, which is totally unique,” says Prof Meintjes.

According to Prof Meintjes, the value of the model lies in the fact that the processes which produce the radiation in AR Sco, can also be applied to produce energy on Earth.

 

Plasma reactors are based on roughly the same processes which apply in AR Sco, and with refining, it could be utilised to generate electricity in future. This will be much cleaner than nuclear energy.

 

The model developed by Prof Meintjes explains all the radiation in the system – from radio waves to X-rays – in terms of electrons accelerated to extremely high energy levels by electric fields in the system, which then produce synchrotron radiation over a very wide band of the electromagnetic spectrum.

Prof Meintjes is currently working on a follow-up article examining the evolution of the AR Sco, in other words, the origin of such a unique system and the final state towards which it is evolving. “My vision for the immediate future is therefore to develop a model for the evolution of the source concerned,” he says.
