The Mid-Atlantic CHTN is one of six participating divisions of the Cooperative Human Tissue Network (CHTN) and is based in the Pathology Department at the University of Virginia. While primarily a resource for cancer researchers, samples provided by the CHTN support projects in many biomedical and basic science fields. In addition to tissue and biofluid specimens, the Mid-Atlantic Division specializes in construction and distribution of tissue microarrays (TMAs). TMAs allow immunohistochemical and colorimetric staining for biomarkers on many samples in parallel. Researchers may quickly obtain … [learn more]

The CHTN is a unique NCI-supported resource that provides human tissues and fluids from routine procedures to investigators who utilize human biospecimens in their research. Unlike tissue banks, the CHTN works prospectively with each investigator to tailor specimen acquisition and processing to meet their specific project requirements. High quality biospecimens are available from surgeries, autopsies and other routine procedures. Types of preservation methods available include fresh, frozen, floating fixative, RNAlater, and paraffin embedded. The CHTN is NCI subsidized allowing for below marke… [learn more]

DTP’s Natural Products Repository is the world’s largest storehouse of natural products. It houses close to >200,000 extracts from samples of more than 70,000 plants and >20,000 marine organisms collected from more than 29 countries, plus extracts of diverse bacteria and fungi. In addition, the NCI Natural Products Repository also includes pre-fractionated natural products extracts created through the NCI Program for Natural Products Discovery. The pre-fractionated extract library has 500,000 partially-purified plated fractions, created from NPB crude extracts, available for screening. The… [learn more]

The Specimen Resource Locator (SRL) is a biospecimen resource database designed to help researchers locate resources that may have the samples needed for their investigational use. This publicly searchable database includes information about biospecimen banks and sample procurement services. The specimens and samples come from non-commercial, either NCI or non-NCI-funded resources. Investigators can search the database and gain access to thousands of specimens of various tumor, organ, and preservation methods. Please submit all SRL inquiries using the “Contact the Expediter” button on t… [learn more]
