Long-read DNA analysis can give rise to errors, experts warn

Phys.org | January 22, 2019

Advanced technologies that read long strings of DNA can produce flawed data that could affect genetic studies, research suggests. New methods that can read long sections of genetic material—categorised by a series of letters—are up to 99.8 percent accurate, however, in a genome of more than 3 billion letters, this may equate to millions of mistakes in the results. These errors may falsely indicate that an individual has a genetic difference that heightens their risk of a particular disease. Researchers say data produced by these technologies should be interpreted with caution, as it may create problems for analyzing genetic information from people and animals. Previously, genetic sequencing technologies were focused on reading short strings of DNA. These sequences would be patched together, which is time-consuming and labor-intensive.

Data integrity is a fundamental element of ensuring compliance in a regulated laboratory and is not a new concept - it dates back decades. However, with computerized laboratory systems now taking the place of paper systems, your compliance strategy must adapt, or you risk difficult regulatory inspections.

Bio-Techne And Carterra Initiate A Clinical Research Collaboration For COVID-19 Variant Analysis

Bio-Techne Corporation | September 08, 2021

Bio-Techne, a leading supplier of high-quality and innovative tools for life science research, therapeutic manufacturing and clinical diagnostics and Carterra Inc., the world leader in high-throughput antibody screening and characterization, today announced a clinical research collaboration studying COVID-19 variants. New variants, such as Delta, can be more easily transmitted and more likely to evade the immune response of vaccinated or previously infected people. 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 leverages Carterra's flagship analytical platform - the LSA® - 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. About Bio-Techne Bio-Techne Corporation is a global life sciences company providing innovative tools and bioactive reagents for the research and clinical diagnostic communities. Bio-Techne products assist scientific investigations into biological processes and the nature and progress of specific diseases. They aid in drug discovery efforts and provide the means for accurate clinical tests and diagnoses. With thousands of products in its portfolio, Bio-Techne generated approximately $931 million in net sales in fiscal 2021 and has approximately 2,700 employees worldwide. About Carterra, Inc. Carterra® is the leading provider of high throughput technologies designed to accelerate and improve the discovery of novel therapeutic candidates. Carterra's LSA™ instrument, software, and consumables for monoclonal antibody (mAb) characterization deliver up to 100 times the throughput of existing platforms in 10% of the time while using only 1% of the sample required by other systems. The LSA combines patented microfluidics technology with real-time high throughput Surface Plasmon Resonance (HT-SPR) and industry-leading data analysis and visualization software to revolutionize mAb screening. Carterra, Inc. is based in Salt Lake City, Utah, and has Customer Experience Centers in San Francisco, Salt Lake City, Boston, and Munich, Germany.
