The Global Unique Device Identification Database (GUDID) contains key device identification information submitted to the FDA about medical devices that have Unique Device Identifiers (UDI).
BLAST finds regions of similarity between biological sequences. The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance. Technical documentation at http://blast.ncbi.nlm.nih.gov/Blast.cgi?CMD=Web&PAGE_TYPE=BlastDocs
BLAST includes several specialized search interfaces: SmartBLAST, Primer-BLAST, Global Align, CD-Search, IgBLAST, VecScreen, CDART, Multiple Alignment, MOLE-BLAST, Searches at a Cloud Provider, BLAST+ Docker Image
The BioProject database provides an organizational framework to access information about research projects with links to data that have been or will be deposited into archival databases maintained at members of the International Nucleotide Sequence Database Consortium (INSDC, which comprises the DNA DataBank of Japan (DDBJ), the European Nucleotide Archive at European Molecular Biology Laboratory (ENA), and GenBank at the National Center for Biotechnology Information (NCBI)).
The NCBI BioSystems Database provides integrated access to biological systems and their component genes, proteins, and small molecules, as well as literature describing those biosystems and other related data throughout Entrez.
Clinical Table Search Service (formerly "lforms-service") is a web service which software programs can use for querying clinical data tables. The API for each table is designed to work with our form field autocompletion package, but can be used by other programs as well. The tables may also be accessed through FHIR APIs. The FAQ page (https://clinicaltables.nlm.nih.gov/faq.html) has further details on terms of service, etc
Provides patients, family members, health care professionals, and members of the public easy access to information on clinical trials for a wide range of diseases and conditions. Technical documentation at https://clinicaltrials.gov/ct2/manage-recs/resources
DailyMed provides high quality information about marketed drugs. This information includes FDA labels (package inserts). This Web site provides health information providers and the public with a standard, comprehensive, up-to-date, look-up and download resource of medication content and labeling as found in medication package inserts. The National Library of Medicine (NLM) provides this as a public service and does not accept advertisements.
dbSNP contains human single nucleotide variations, microsatellites, and small-scale insertions and deletions along with publication, population frequency, molecular consequence, and genomic and RefSeq mapping information for both common variations and clinical mutations. dbSNP tutorials can be found at https://github.com/ncbi/dbsnp/tree/master/tutorials
