Stock report help

Last Updated: 5 December 2006

The Stock Report provides information on Drosophila stocks in stock centers and laboratories that have made their stock lists available to FlyBase. Most of these stocks exist as living cultures, but some are available only as ethanol-preserved specimens and some strains are available as both living cultures and purified genomic DNA. FlyBase captures the collection's genetic description of each strain and, when available, provides links to a collection's web site for additional stock information.

Requests for stocks and all other stock-related communications should be directed to the collection rather than to FlyBase.

This is a field-by-field guide to the information that is provided in the Stock Report.

General Information

The short name that FlyBase uses for the collection that includes this stock. If the collection maintains a web site the short name links to that site.

Collection Type

FlyBase types stock collections as either stock center collection or laboratory collection. Stock centers are organized for the purpose of collecting and distributing strains and are funded for this activity. Laboratory collections grow out of research-driven activities and typically use research funds for maintenance and distribution. Stocks should be requested from a laboratory collection only when they are unavailable from a stock center.

Stock Number

The numeric or alphanumeric identifier used by the collection for the stock. Not Available appears when a stock does not have a stock number. Stock Number is linked to the collection's web page for that stock if a page is available.


The organism that the strain originates from, with the initial letter of the genus and the full species name listed.

FlyBase ID

The FlyBase identifier number of the stock, used to uniquely identify the stock in the database.


The date that the stock was entered into the chado database underlying FlyBase (we migrated to the chado database on 2006-08-22) and the date that the stock report was last updated. The dates are in the format: year-mm-dd.

Stock List Description

The genetic description of the strain as provided to FlyBase.

FlyBase Genotype

The Stock List Description represented in valid FlyBase nomenclature. Genotype components are linked to their respective FlyBase reports. FlyBase curates genotypes for the stock center collections and for the Exelixis Drosophila Stock Collection at Harvard Medical School (short name Harvard), but not for other laboratory collections.

State of Stock

This section is only displayed if it is populated with data.

A single controlled vocabulary term from the FlyBase Controlled Vocabulary that describes the state of the stock if the stock is other than a living stock.


This section is only displayed if it is populated with data.

A list of categorizations or features of the stock using controlled vocabulary terms from the FlyBase Controlled Vocabulary.

To Request Stock

Instructions for requesting the stock, with a link to a web order form if available.
