How is gene expression data collected?
A microarray is a laboratory tool used to detect the expression of thousands of genes at the same time. DNA microarrays are microscope slides that are printed with thousands of tiny spots in defined positions, with each spot containing a known DNA sequence or gene.
What is a gene database used for?
A genetic database is one or more sets of genetic data (genes, gene products, variants, phenotypes) stored together with software to enable users to retrieve genetic data, add genetic data and extract information from the data.
When to submit gene expression data to NCBI?
The data does not need to be submitted at the time of BioProject registration. Guidelines and requirements for submitting genotype and phenotype association data to dbGaP. Submit expression data, such as microarray, SAGE or mass spectrometry datasets to the NCBI Gene Expression Omnibus (GEO) database.
Which is the best database for gene expression?
Gene Expression Omnibus (GEO) Database. A public functional genomics data repository supporting MIAME-compliant data submissions. Array- and sequence-based data are accepted and tools are provided to help users query and download experiments and curated gene expression profiles.
How does GeneRIF work in the NCBI database?
GeneRIF provides a simple mechanism to allow scientists to add to the functional annotation of genes in the Gene database. A single entry point for submitters to link to and find information about all of the data submission processes at NCBI.
How do I get NCBI records from Entrez?
Use the text query to retrieve the records from the appropriate Entrez database. For guidance on creating an Entrez text query, see the Entrez Help or help documents linked to the home page of the Entrez database that contains the data you want. If desired, change the display format using the Display pulldown menu.
