Angstrom Bio Launches AMPD™, Platform for High-accuracy, High-frequency, Low-cost COVID-19 and Respiratory Pathogen Testing

Angstrom Bio | October 14, 2020

Angstrom Bio, Inc. today announces the launch of AMPD™, its nanopore sequencing and machine learning powered platform for high-accuracy, high-frequency, low-cost COVID-19 and respiratory pathogen testing. AMPD leverages the extreme resolution and bandwidth of nanopore sequencing to provide the accuracy and volume necessary to detect the earliest stages of exposure to pathogens like SARS-CoV-2 and influenza and to enable schools and places of work to reopen safely and confidently. Angstrom will partner with businesses, schools, and public sector organizations to implement cost-effective testing programs designed to maximize employee and stakeholder safety and to minimize the potential for operational disruption. The company intends to bring more than 1,000,000 results per day online in 2021, at prices that enable nearly any organization to have access to repeated, high-quality testing. "Despite the tremendous progress made in diagnostics since the beginning of the pandemic, it is clear that testing today remains an area plagued by too many tradeoffs between availability, accuracy, and speed, as well as ease of collection, cost, and adaptability," said Carlos F. Santos, Ph.D., Angstrom's CEO. "We designed AMPD to eliminate the need for such tradeoffs. By leveraging the extraordinary resolution and bandwidth of nanopore sequencing and the power of our machine learning-driven diagnostic pipelines, and by rethinking pre-COVID-19 diagnostic workflows, we have been able to design a platform that can provide the extreme scale and accuracy required to meet the unprecedented challenges posed by COVID-19." At the heart of AMPD is a novel nucleotide chemistry and computational biology platform designed to harness the bandwidth and resolution of Oxford Nanopore Technologies' nanopore Third-Generation Sequencing (TGS) systems. Unlike diagnostic systems that rely upon fluorescence-driven workflows for diagnostic analysis, nanopore TGS counts individual DNA molecules that pass through each of hundreds of nano-scale pores in a specially-designed membrane. The combination of single-molecule resolution and parallelism allow for the processing of tens of thousands of diagnostic results per AMPD run, while enabling orders of magnitude greater sensitivity than is currently available. This makes AMPD ideal for parties that require timely access to affordable, repeated testing, but that cannot compromise safety.

GenScript and Gladstone-UCSF Institute of Genomic Immunology Collaborate on Groundbreaking Non-Viral Cell Therapy Study

Genscript Biotech Corporation | September 23, 2022

GenScript USA Inc., the world's leading life-science research tools and services provider, is collaborating with researchers at the Gladstone-UCSF Institute of Genomic Immunology to advance the development of new, non-viral cell therapies that modify genomic sequences in the pursuit of more effective cell therapy products while limiting the cellular toxicity that is typically associated with previously available methods. A new study, published in Nature Biotechnology, details methods for achieving highly efficient non-viral knock-in using GenScript's GenExact™ single-strand DNA modified with Cas9-target sequences. This method achieved up to ˜40% knock-in efficiency in primary immune cell types. One powerful application of CRISPR/Cas genome editing technology involves the precise insertion of DNA sequences via the HDR pathway. Traditionally, researchers have relied on viral vectors to deliver DNA insertion templates used for gene therapy into cells. However, difficulties manufacturing large amounts of clinical-grade viral vectors have delayed getting cell therapies to patients. Additionally, viral vectors can insert genes at any location within the genome, leading to safety concerns. Previous research by the group at Gladstone and UCSF has shown that synthetic DNA templates can be delivered without the use of viral vectors, but high levels of double-stranded DNA can be toxic to cells, resulting in low efficiency. Efficiency can be improved using a modified version of the DNA templates that can bind to the Cas9 enzyme. However, additional work was required to improve the yield of successfully engineered cells and to make the process compatible with the manufacturing of future cell therapies. Those goals motivated the team's current study. In this study, the team tested modified GenExact ssDNA designed with Cas9-targeted sequences to determine if the gene-editing efficiency could be improved with lower toxicity. First, synthetic sgRNA was complexed with Cas9 protein to form a RNP complex. Then the RNP and ssDNA template were delivered into the cell via electroporation, enabling efficient gene editing. The team discovered that this combination of GenExact ssDNA with Cas9-targeted sequence offers up to 40% knock-in editing efficiency with minimal cellular toxicity. This approach can accelerate the development and manufacture of novel, high-yield non-viral gene therapies — and at lower cost. "We are very proud to have collaborated on this groundbreaking scale-up work by the talented team at Gladstone and UCSF. GenScript is excited for the opportunities that this high-yield cell-line engineering process will provide to our customers," said Ray Chen, Ph.D, president of GenScript Life Science Group. "We were very happy to partner with Genscript on critical experiments demonstrating high efficiency and yield of CAR knock-in cells at clinical scale. The long ssDNA produced by Genscript exceeded our expectations and helped us clearly demonstrate the potential for future therapeutic applications using these methods.", Brian Shy, MD, PhD, a former clinical fellow in the lab of Alex Marson, MD, PhD, director of the Gladstone-UCSF Institute of Genomic Immunology About GenScript Biotech Corporation GenScript Biotech Corporation is a global biotechnology group.
