Based on next generation sequencing, Azenta Life Sciences, formerly GENEWIZ’ high-throughput gene expression (HT-GEx) screening, similar to DRUG-Seq, is an optimal approach for drug discovery and analysis. Unlike microarrays which bear inherent limitations, this method offers rapid, unbiased 3' gene expression screening that provides a complete cell-to-data analysis of the transcriptome at a lower cost than standard RNA sequencing. Working directly from lysate, high-throughput gene expression screening saves both time and money by removing the need to purify RNA and performs 3’ transcript tagging that reduces the required sequencing depth.

Webinar Series | Advancing Transcriptomics: Gene Expression Screening, Single-Cell RNA-Seq, and Beyond

With this two-part webinar series, go beyond traditional transcriptomics and learn about the various NGS approaches available for gene expression analysis. In part 1, we take an in-depth look at various gene expression approaches, including RNA-Seq, single-cell RNA-Seq, digital spatial profiling, and more. In part 2, we explore the data generated from these approaches and how they can complement each other and confirm findings.
