High-Throughput Gene Expression Screening
High-throughput gene expression (HT-GEx) screening is an RNA-Seq-derived approach we developed for optimal drug discovery and analysis, similar to DRUG-Seq. Unlike microarrays, our method offers rapid, unbiased, 3′ gene expression screening, providing complete cell-to-data analysis of the transcriptome at a lower cost than standard RNA sequencing. Working directly from lysate, GENEWIZ High-Throughput Gene Expression Screening works directly from cell lysate, saving both time and money by removing the need for RNA purifications. Additionally, the method performs 3’ transcript tagging to reduce required sequencing depths.

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.
