Key Services, Technologies, & Equipment
High-throughput DNA-seq and RNA-seq. ATG offers whole-genome sequencing, bulk RNA-seq, ChIP-seq, RIP-seq, exome, and small RNA analysis using the Singular Genomics G4 sequencer. Starting material can include cells, saliva, blood, and FFPE or fresh-frozen pathology samples.
10x Genomics single-cell sequencing. Using the 10x Genomics Chromium controller, together with a Countess II Automated Cell Counter and a Miltenyi gentleMACS Octo Dissociator to create single-cell suspensions, ATG staff prepare the samples and construct the NGS libraries for NGS of DNA and RNA.
10x Visium-HD and Xenium in situ for whole-transcriptome and targeted gene expression analysis. In partnership with the Human Tissue Repository & Tissue Analysis (HTR-TA) Shared Resource, the ATG offers spatial whole transcriptome analysis of fresh-frozen and FFPE tissues using the Visium-HD and Xenium in situ spatial gene expression technologies from 10x Genomics. Visium HD spatial gene expression delineates the complete transcriptome of entire tissue sections, providing morphological context and high cellular resolution. Xenium in situ enables the high-throughput subcellular mapping of up to 5,000 genes alongside multiplexed proteins within the same tissue segment, obtained in collaboration with the HTR-TA for sample preparation.
NGS data analysis, scRNA-seq, and interactions with the Biostatistics and Bioinformatics & Data Science (BDS) Shared Resources. The ATG coordinates with the Biostatistics and BDS Shared Resources to establish quality control analytics and develop data analysis pipelines for the G4-Singular data, including single-nucleotide variant (SNV) detection from DNA samples, gene expression analysis, variant analysis from RNA, scRNA-seq data, detection of fusion transcripts from RNA-seq, and copy number variant (CNV) analysis. The processed files are stored in our secure AWS cloud account and used for downstream analyses by ATG staff or the BDS, utilizing customized R scripts. ATG Technical Director Brayer serves a dual role as a senior bioinformatician and a liaison with the Biostatistics and BDS Shared Resources to facilitate study design and data analysis.
Data storage and computing. The ATG maintains a secure, HIPAA-compliant, and IRB-approved AWS account where large datasets can be stored and analyzed. All data are de-identified, encrypted in transit, and stored. Only authorized users have access, which requires two-factor authentication. For the security of genomic data, the ATG adheres to the policies outlined in the NIH Security Best Practices for Controlled-Access Data, Subject to the NIH Genomic Data Sharing Policy.
Other services. The ATG has an Agilent BioAnalyzer, Qubit fluorometer, a Miltenyi gentleMACs Octo Dissociator with heaters (for generating single-cell suspensions from tissue), a Countess II automated cell counter, and ThermoFisher QuantStudio 6 Pro Q-PCR, which are available for use by UNMCCC members. A Qiagen EZ2 DNA/RNA extraction robot is available for high-volume, automated nucleic acid extraction.
