The Bacterial Diversity Metadatabase BacDive is the worldwide largest database for standardized bacterial phenotypic information. Its mission is to mobilize research data on strain level from internal files in culture collections (e.g. CABI, CIP, CCUG, DSMZ) as well as from primary literature and make it freely accessible. Today BacDive offers data on 93,254 bacterial and archaeal strains, including 19,313 type strains and thereby covers approx. 90% of the validly described species. Within over 600 data fields the topics taxonomy, morphology, physiology, origin, molecular data, and cultivation conditions are covered. The database offers systematic access to phenotypic data. BacDive thereby enables queries like "show me all strains that grow under certain conditions” by using the Advanced search or queries like “show me all strains isolated from a marine environment” by using the Isolation source search. With currently 15,357 API® tests for 27,634 strains, BacDive also offers the worldwide largest API® test collection, which can be queried using the API test finder tool.

The mission of the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health, is to advance science on the causes and consequences of drug use and addiction and to apply that knowledge to improve individual and public health. NIDA, in collaboration with other NIH Institutes, Centers, and Offices, and other federal partners, supports two large prospective developmental studies, the Adolescent Brain Cognitive Development SM (ABCD) Study and the HEALthy Brain and Child Development (HBCD) Study. The NIH Brain Development Cohorts (NBDC) Biorepository Portal serves two major purposes for the ABCD and HBCD studies: It facilitates the collection of samples by study staff, and it maintains a database of stored samples and sample associated metadata for the research community. Researchers can browse the inventory of available samples using the Biospecimen Explorer, and request biospecimens to conduct their own analyses. By providing these services, the NBDC Biorepository Portal aims to further support research on child and adolescent health and development.

PrimerBank is a public resource for PCR primers. These primers are designed for gene expression detection or quantification (real-time PCR). PrimerBank contains over 306,800 primers covering most known human and mouse genes. There are several ways to search for primers: GenBank Accession, NCBI protein accession, NCBI Gene ID, Gene Symbol, PrimerBank ID or Keyword (gene description) or you can blast your gene sequence against the primerbank Sequence DB.

NCBI Virus is an integrative, value-added resource designed to support retrieval, display and analysis of a curated collection of virus sequences and large sequence datasets. We are a community portal for viral sequence data, and our goal is to increase the usability of data archived in GenBank and other NCBI repositories. NCBI Viral Genomes Resource is a collection of virus genomic sequences that provides curated sequence data, related information and tools. It includes all complete viral genome sequences deposited in the International Nucleotide Sequence Database Collaboration (INSDC) databases, i.e. DDBJ, EMBL, and GenBank. Data are organized by viral taxonomy, and reference sequence records (RefSeqs) from one or more genome sequences for each viral species. After a RefSeq has been created for a species, other complete genomes from that same species are indexed as neighbors to the RefSeq.

The Ocean Data Explorer allows scientists, managers, and the general public to discover and access information including real-time conditions, operational and research forecasts, satellite observations, and other spatially referenced datasets that describe the regional biological, chemical, and physical characteristics. A number of functions are available including custom comparisons of datasets, instrument metadata and provenance information, and dataset download in a variety of formats.
