The BDSC collects, maintains, and distributes genetically defined strains of Drosophila melanogaster with significant research value.
Emphasis is placed on genetic tools that are useful to a broad range of investigations. These include basic stocks of flies used in genetic analysis such as marker, balancer, mapping, and transposon-tagging strains; mutant alleles of identified genes, including a large set of transposable element insertion alleles; defined sets of deficiencies and a variety of other chromosomal aberrations; engineered lines for somatic and germline clonal analysis; GAL4 and UAS lines for targeted gene expression; enhancer trap and lacZ-reporter strains with defined expression patterns for marking tissues; and a collection of transposon-induced lethal mutations.
Approximately 29,000 fly strains are currently available. Up-to-date stock lists are available for searching, browsing, or downloading/copying at the Internet site. An order form is available on the same site. One small subculture is provided of each requested stock. Larger quantities of animals cannot be provided by the center. Requests may be submitted via a web-based automated ordering system. Stock center scientists are available to answer questions about center stocks, use of the database, or general questions about Drosophila genetics for researchers new to the field. New users of the collection must contact the center for a Bloomington user number (BUN) before ordering stocks.
