On Sept. 8, 2021, Bio-Techne and Carterra announced a clinical research collaboration studying COVID-19 variants. To assess immune responses to new variants and to plan for intervention mechanisms that avoid vaccine escape, scientists and epidemiologists need a fast and effective assay.

The partnership leveraged Carterra’s flagship analytical platform – the LSAﾮ – to characterize panels of SARS-CoV-2 spike and receptor-binding domain (RBD) variants in an information-rich assay. The SARS-CoV-2 variants were developed by Bio-Techne and used to fast-track the new, scalable assay for measuring the potential risks that new variants may evade the ability of the immune system to block the virus.

Bio-Techne has been leading the way in COVID-19 research reagent and immunoassay development enabling scientists to make discoveries leading to effective diagnoses, therapies and vaccines. The company was first to market with COVID-19 research protein variants and has significant expertise with SARS-CoV-2 antibody quantitation. Bio-Techne and Carterra will focus this collaboration on more than 40 variants, including the Delta variant that is prevalent today, and emerging variants as they are discovered.

The Carterra LSA will be used to generate high-definition insights with over 120 data points from patient serum samples, including a variant profile, ACE-2 blocking potential, and isotyping profiles of immunoglobin response. The LSA’s hands-free, high-throughput setup requires only 2 µL of patient serum and provides for the analysis of new and emerging variants in the ever-evolving field of COVID-19 research.

Carterra’s LSA instrument is the fastest, most sensitive and flexible biosensor platform on the market. Combining proprietary flow printing microfluidics with High Throughput Surface Plasmon Resonance (HT-SPR) technology, the LSA enables detailed screening and characterization of vast antibody or variant libraries, including full kinetic profiles. With the ability to generate real-time binding data for 384 proteins on one chip and assay up to 1152 patient samples in a single unattended run, the LSA significantly improves efficiency and speed in both drug discovery and clinical research.
