Expression Analysis Core

expression_analysis_core_bannerThe mission of the Expression Analysis Core at the UC Davis Genome Center is to provide services and technologies for gene expression analyses at the genomic level. We are focused on exploiting ultra high throughput sequencing and Illumina expression arrays. The PacBio Iso-Seq protocol enables full-length transcript sequencing and thus the discovery new gene isoforms.  Workshops in these technologies are an important part of facility operations. We also offer access to liquid handlers and nucleic acid analyzers to facilitate your experiments.

    The 10X Genomics Single Cell system is the single-cell expression profiling platform enabling the analysis of large cell numbers at the highest capture efficiency (of up to 65%). The technology allows for high-throughput single cell transcriptomics of many different cell types.  A new protocol now also allows  single-nuclei expression profiling. This progress makes the platform now applicable also to brain tissue. The flexible ...
  • RNA-Seq Workshop – Library Preparation and Introduction to Data Analysis – August 9th to 11th 2017

    May 12, 2017
    August 9th, 9 a.m. – August  11th,  5 p.m. RNA-seq has revolutionized the way we address complex biological questions, allowing for differential gene expression, differential transcript analysis, as well as transcriptome assemblies. As sequencing output rapidly increases and sample numbers increase, library preparation becomes one of the major bottlenecks.

  • Another Update on the Barcode Mis-Assignment Issue: Illumina’s White Paper

    April 19, 2017
    Illumina published a white paper today on the barcode mis-assignment issue (Illumina calls it somewhat euphemistically “barcode hopping”). In contrast to the Sinha et al. paper, which only presented data for libraries with NextSeq adapter sequences, the white paper shows that the issue is also relevant for TruSeq style adapters. The conclusions are fairly similar to the ones drawn in ...
