Long Read Sequencing (Third Generation) and Next Generation Sequencing (Second Generation)

DNA and RNA sequencing is the process of determining the nucleotide order of a given DNA fragment. The nucleotide sequence encodes the necessary information that allows living things to survive and reproduce. Determining the sequence is therefore useful in researching into how organisms live. Our core facility provides many sequencing options to meet your individual needs, utilizing (a) Oxford NanoPore GridIONx5 Long-Read Sequencing (by reading the nucleotide sequences at the single molecule level), and (b) Illumina Short-Read Sequencing (by massive parallel sequencing of millions of DNA fragments and yielding substantially more throughput reads quickly).

  • Whole transcriptome sequencing (RNA-Seq)
  • Small RNA sequencing (miRNA-Seq)
  • Whole exome sequencing
  • Targeted resequencing
  • Whole genome sequencing

10X Single Cell Sequencing

The Chromium 10x genomics 3’ Single Cell Gene Expression Solution provides a comprehensive, scalable solution for cell characterization and gene expression profiling of hundreds to tens of thousands of cells. The Chromium Single Cell Immune Profiling simultaneously examines the cellular context of the adaptive immune response and immune repertoires of hundreds to tens of thousands of T and B cells in human or mouse tissue on a cell-by-cell basis. The newest one is the Chromium Single Cell ATAC (Assay for Transposase Accessible Chromatin), which accelerates the understanding of the regulatory landscape of the genome, providing insights into cell variability.

  • Chromium™ Single Cell 3’ Library Construction
  • Chromium™ Single Cell 5’ Immune Library Construction (Single Cell V(D)J + 5’ Gene Expression)
  • Chromium™ Single Cell ATAC Solution

Microarray Analysis

The human genome contains approximately 25,000 genes, and each cell of the human body contains a copy of every gene. At a given moment, each cell has a combination of genes that are turned on and off. This combination of genes that are "on/off" can change at any time depending on internal and external stimuli.

Thus, it can be very important to determine which genes are turned on and off. Microarray analysis allows us to do this. The TCGB is equipped with various platforms to meet your research needs.

  • Gene expression profiling
  • SNP genotyping
  • Copy number variation analysis
  • Global methylation
  • ChIP-ChIP analysis
  • miRNA profiling
  • Advanced microarray data analysis
  • QRT-PCR confirmation

Advanced Data Analysis

The TCGB has various academic and commercial data mining software and other resources for genomic data analysis, including Partek flow, VarSeq, Ingenuity Pathway Analysis, Falcon automated genomic analysis system,Hoffman2 data analysis clusters, UCLA CASS server, Illumina basespace Sequencing Hub professional, Amazon cloud HIPAA compliant research computing, and storage system server.

  • Standard NGS & Microarray data analysis
  • Advanced and customized data analysis
  • Online data delivery, long term storage and data retrieval
  • Data analysis tutorial

Other Services

Educational workshops are offered annually. Our core facility also provides RNA/DNA extraction; RNA/DNA quality control and quantification; cDNA synthesis for quantitative-PCR; and QRT-PCR.


The GSR occupies approximately 2,568 square feet of laboratory space on the third floor of the Center for Health Sciences, CHS 38-123, 38-126 and 33-388. It is operated by eleven experienced genomic scientists. The GSR is a high throughput genomic center utilizing the equipment listed below. In addition to offering wet-lab services, the GSR has developed a broad informatics infrastructure and an efficient means for data acquisition, storage, and analysis. We have access to advanced software including Partek flow, VarSeq, Ingenuity Pathway Analysis, and Falcon automated system, which significantly enhance the overall capacity of TCGB to rapidly process and transform the large quantity of data into novel findings.

Operational Policies/Procedures

The GSR has the following operational policies:

  • Before each experiment, the director and co-director schedule two meetings with the investigator and their staff. The first meeting is to discuss experimental strategy and the second meeting is to discuss technical issues and expenses
  • When a sample arrives, the GSR performs vigorous quality control before, during, and after each experiment. When quality meets established standards, the lab manager delivers the data to the investigator and saves a copy on the GSR data storage server for a minimum of two years
  • After completion of the experiment, the GSR assists investigators in data analysis, publication, and grant application preparation, on request

To ensure the highest quality services, the GSR has the following use policies:

  • Quality assurance: Data quality assurance occurs when initial samples pass GSR quality controls (QC). The GSR follows strict QC guidelines to ensure data quality equal to or above that of quality specifications by instrument or kit manufacturers.
  • Flexibility: Investigators can use GSR services at any stage they choose. As an example, GSR services can start from tissue and deliver analyzed data or start from a pre-constructed library and deliver raw data. The GSR will make every effort to meet investigators’ specific scientific needs.
  • Hours of operations: The GSR is accessible from 7:30 AM to 5:30 p.m., Monday through Friday. Users can access the GSR after-hours by arrangement with the lab manager.
  • Turnaround time: GSR automation enables quick turnaround times in general. Although the GSR prioritizes JCCC investigators projects, 85% of NGS samples process within two weeks, and 100% of microarray samples process within one week of receipt for JCCC, non-JCCC, and non-UCLA users alike.
  • Priority: JCCC members are given highest priority, non-JCCC UCLA investigators have second priority, and outside users are assigned the lowest priority. However, amongst outside users, cancer researchers from other cancer centers receive preferable scheduling.
  • Low price: The GSR has three price tiers for each service. The fees for the majority of services are below or similar to reagent costs for JCCC members, and are below or similar to “reagent costs + labor” for non-JCCC UCLA investigators. The large number of outside users make these preferential prices possible for JCCC investigators (for a full list of prices, see
