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%).
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. This workshop provides comprehensive hands-on training in the preparation of high quality RNA-Seq libraries for the Illumina platform.
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.
A "much-tweeted" manuscript was recently published on Biorxiv, investigating the barcode mis-assignment issues affecting HiSeq 3000, 4000, and HiSeq X, reported in our last newsletter. Please see the manuscript here: Sinha et al.
New High-Throughput Gene-Expression Analysis Services (3'Tag-Seq)
The DNA Technologies and the Bioinformatics Cores have been working for more than half a year with a simplified RNA-Seq protocol that promises to drastically reduce the costs of many gene-expression studies, while fully maintaining the precision of the analysis.
The new approach is called 3'Tag-Seq (or TagSeq, 3'Tag-RNA-Seq, Digital RNA-seq but these names have also been used for a variety of different protocols).
PacBio Sequel Version 2 Chemistry
We have recently beta-tested the new PacBio Sequel chemistry (V2). The tests have demonstrated significant yield and read-length improvements. All current and future Sequel runs will be carried out with the new chemistry. In addition to the V2 chemistry change, the Sequel software has been updated and allows now for 10 hour movie recordings (previously the limit was 6 hours, as it still is for the RSII).
We will be open before, after, and between the holidays and closed only on official UC holidays. The UC holidays are Friday the 23rd, Monday the 26th, Friday the 30th, and Monday the 2nd.Happy Holidays! The DNA Tech Core Staff.
Please joins us for the seminar: Simultaneous “multi-omic” measurement of gene fusions, mRNA, & proteins at 800-plex using single-molecule optical barcodes.Thursday, December 1st: 2pm to 3 pm Genome Center Auditorium (GBSF, #1005)

ABSTRACT
The ability to measure changes to DNA, RNA, and protein is crucial to developing a comprehensive understanding of biology in the genomics era
Pacific Biosciences (PacBio) has recently published a high quality de novo genome assembly for Arabidopsis based on the data of only two Sequel SMRT-cells. The Sequel is the second generation PacBio sequencer and generates up to 7x more reads per SMRT-cell compared to the first generation PacBio RSII sequencer.

The UC Davis DNA Technologies and Expression Analysis Cores have been designated a Campus Research Core Facility
From the official announcement:
" .... This designation provides a strategic platform to ensure state-of-the-art research capabilities provided in a cost-efficient manner. The designated laboratories are expected to develop and represent best practices for core facility operation and emerge as centers of excellence for the university.
We would like to thank everybody who participated in our user survey!
Your input is highly appreciated and will help us improve our services.
The results are available here: https://www.surveymonkey.com/results/SM-Q67N6H9J/
73 DNA Technologies and Expression Analysis Core users did participate.
Our latest generation Illumina HiSeq3000 sequencer has been upgraded to a HiSeq4000. This means the option to run two flowcells in parallel was enabled. Thus, the sequencer offers now twice the throughput. The chemistry and reagents do not change as should the yields per lane and the high quality of the data.
