Industry news

Aptamer Group, the developer of diagnostic and therapeutic Optimer™ reagents, has announced a commercial partnership with Mologic, a leading developer and manufacturer of lateral flow and rapid diagnostic tests. The partnership will work towards CE marking of Aptamer Group’s AptaDx SARS-CoV-2 lateral flow rapid antigen test for professional use, to detect the SARS-CoV-2 spike protein antigen in anterior nasal swabs. Initial test analysis with laboratory samples has demonstrated excellent sensitivity being able to detect as little as 1000 virus particles per mL, with further clinical validation to support the CE marking to be performed at the Integrated COVID Hub North East in Newcastle, UK.

Testing of the Optimer reagents has shown that they recognize the original viral strain and the dominant emerging variants. These variants are the ‘Kent’ variant, B.1.1.7, the Danish variant, D614G, and the South African variant, B1.351 (also known as 501Y.V2).

Working with Mologic will help to accelerate the development of Aptamer Group’s test to market and provide Aptamer Group with manufacturing capacity through Mologic, in addition to other partners, for the final commercialized test. Aptamer Group is involved in ongoing discussions with other global manufacturers to access additional capacity for the delivery of several million tests per month.

Aptamer Group’s SARS-CoV-2 rapid antigen test will be the first aptamer-based diagnostic test to be commercialised. Aptamers are synthetic nucleic acid-based affinity reagents, produced by solid phase synthesis offering simple, scalable, and highly cost-effective affinity solutions. The production of aptamers compared to standard protein-based affinity reagents offer significant cost advantages, allowing large scale development and delivery of tests globally, including to low- and middle-income countries.

Further updates will be provided following the completion of the clinical evaluation of the test performance.

Dr Arron Tolley, CEO of Aptamer Group, commented: “‘Following our initial collaboration with Mologic to develop the AptaDx SARS-CoV-2 rapid antigen test over recent months, I am delighted to have now extended our partnership to progress the CE marking of Aptamer Group’s test. We have seen encouraging laboratory performance of the rapid antigen test and have demonstrated the detection of the current main SARS-CoV-2 variants. We are now keen to take the test through clinical evaluation with Newcastle’s Integrated COVID Hub to support the CE marking with Mologic. I look forward to updating the market on clinical and commercial progress in due course.”

Mark Davis, Chief Executive Officer of Mologic, said: “The agreement with Aptamer Group further demonstrates our commitment to efforts tackling the COVID-19 pandemic, globally. In doing so, Mologic and our partners are able to offer an accelerated route to market, with increased manufacturing capacities, to crucially support expanded access to these rapid test technologies.”

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Cellular PathologyCellular Pathology deals with the microscopic analysis of tissue samples and cells. Sample preparation and processing includes fixation, staining, sectioning and slide mounting, using equipment such microtomes and cryostats. In choosing immunohistochemistry and immunocytochemistry kits, consider chromogens, staining method, antibodies, microscopes and imaging.Biopharmaceutical AdvancesBiopharmaceutical advances follow the development of pharmaceuticals derived from biotechnology, also known as biotechnology medicines. Biopharmaceuticals may be produced from cell lines, plants, or microbial cells. Important considerations of biopharmaceutical use include application, cost, production process and purification.Clinical TrialsClinical Trials, an essential part of drug discovery process, assess the safety and effectiveness of a new medication or device in the pharmaceutical industry. Clinical Trials are a phased process (Phase 0, Phase I, Phase II, Phase III and Phase IV) which begins after initial preclinical testing.Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Clinical GeneticsMolecular Genetics covers the analysis of hereditary genetic disease and chromosomal abnormalities. Genetics can be analysed using DNA, RNA, and protein microarrays, PCR, RT PCR and DNA sequencing. Genetic equipment includes genetic workstations, thermal cyclers, cooling blocks and electrophoresis products. Diagnostic kits are used for DNA / RNA extraction and purification.Clinical MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.
