Antibodies are among the most commonly used tools in the biological sciences - put to work in many experiments to identify and isolate other molecules. NCI’s Antibody Program has developed more than 500 available antibodies that have been designed and optimized, with the vast majority developed as fit-for-purpose reagents.
COVID-19 is an emerging, rapidly evolving situation.

Data Release-20 from the Genomic Data Commons (GDC) includes genomics from a new CPTAC project!
The CPTAC Proteogenomic Confirmatory Study examined prospectively collected colon, breast and ovarian tumors for analysis, including harmonized whole exome sequencing, RNA-Seq, and miRNA-Seq that is now available. Complimentary proteomic and phosphoproteomic analysis can also be found on the CPTAC Data Portal and the Proteomic Data Commons (PDC).
CPTAC has provided the Genomic Data Commons (GDC) with genomic data from over 600 cancer patients with diverse disease types including...

Investigators with the Clinical Proteomic Tumor Analysis Consortium (CPTAC) have generated the most comprehensive multi-omics dataset for clear cell renal cell carcinoma (ccRCC), the most commonly diagnosed kidney cancer subtype. The investigators used integrative proteogenomics, to reveal new insights into kidney cancer.
October 23, 2019
Over three hundred proteomic explorers and Clinical Proteomics Tumor Analysis Consortium (CPTAC) participants from around the country convened on the NIH Bethesda campus to share cutting-edge proteogenomic research in the first ever, public-facing CPTAC Scientific Symposium.

Hepatocellular carcinoma (HCC), the most common form of liver cancer, occurs most often in people with hepatitis B or C viral (HBV or HCV) infections who drink large amounts of alcohol. Unlike the recent progress of antiviral-eliminating therapy for HCV, current antiviral therapy is only able to reduce rather than eliminate HBV and is estimated to affect 292 million peop

RAS gene mutations and their pathways have stymied cancer researchers for decades. RAS-driven cancers make up more than 30% of all human cancers due to their association with uncontrollable cell growth, death-signal evasion, and drug resistance. In 2014, the National Cancer Institu

Genomics platform cBioPortal offers a “biologist-friendly” resource for querying mutations, copy number variations and gene expression. It contains data from The Cancer Genome Atlas (TCGA) which includes proteomics data in the form of arrays that use antibodies to track protein levels. CPTAC mass spectrometry-based proteomics, however, has more information than the arrays provide.

The Journal of Molecular & Cellular Proteomics has released a special issue this month (August 2019) on Multi-Omics Integration. The issue sets out to show how multi-omics research is integral to the understanding of biological systems. It touts work from several of our CPTAC investigators who share their cutting

Proteomic profiling often entails using a large sample input to explore the dynamic nature of protein expression and regulation. However, there are instances when researchers have the opposite due to prior methodology such as fluorescence activated cell sorting (FACS) or when dealing with patient samples.
