挑战
AstraZeneca, a global biopharmaceutical company, was facing challenges in automating data processing and increasing the quality of results. The company was using Acoustic Droplet Ejection (ADE) technology for high-throughput screening (HTS), which introduced samples into a mass spectrometer. However, the increase in throughput brought by Acoustic Mist Ionization Mass Spectrometry (AMI-MS) technology resulted in large amounts of data that needed efficient processing. The main challenges included eliminating laborious and potentially error-inducing manual interventions, guaranteeing data quality and traceability, adapting data processing to different targets and screening strategies, obtaining insightful visualization to speed assay development, and integrating MS data into screening data analysis platforms.
关于客户
AstraZeneca is a global, science-led biopharmaceutical company that develops innovative medicines used by millions of patients worldwide. The company is committed to discovering, developing, and delivering innovative, meaningful medicines and healthcare solutions that enrich the lives of patients. The medicines developed by AstraZeneca are used in three main therapy areas - Oncology, Cardiovascular & Metabolic Disease and Respiratory. The company also is selectively active in the areas of autoimmunity, neuroscience and infection. AstraZeneca operates in over 100 countries and its innovative medicines are used by millions of patients worldwide.
解决方案
AstraZeneca partnered with Genedata to develop a flexible, automated data processing workflow for efficiently processing the large amounts of data generated by the AMI-MS screening platform. The solution, Genedata Expressionist, is based on automated, customizable workflows, in which data is subjected to sequential processing steps. The software automatically parses and assigns spectra to their respective 384-well plate well, eliminating the need for manual scanning of barcodes. Advanced algorithms ensure the highest data quality by automatically quantitating peaks of interest using dynamic peak detection and clustering algorithms. The software also offers flexibility in assay design, allowing AstraZeneca’s scientists to employ any MS-based screening approach. The results are seamlessly exported to Genedata Screener, where plate-wise visualization of results enables routine QC and fast identification of potential hits.
运营影响
  • Significant time savings: The data processing workflow requires a single click and takes around 25 minutes for a data set obtained from 150 × 384-well plates. Previously, processing of such data sets—including the potential error-inducing manual steps—required 3 hours.
  • Higher-quality, more reliable data: By eliminating potential error-inducing manual steps, automated Genedata Expressionist data processing greatly increases the level of confidence in the quality of the data.
  • Flexibility in assay design: Because it can be used for processing data from any MS instrument or application, Genedata Expressionist offers AstraZeneca’s scientists the ability to employ any MS-based screening approach, and the opportunity to explore biological experimental spaces outside conventional substrate/product assay strategies.
数量效益
  • Seven-fold decrease in processing time with elimination of potentially error-inducing manual interactions.
