General Information of NIG-FLY RNAi stocks


How to use NIG-FLY Stock Center



 Q. What kind of fly stocks does NIG-FLY have?

A. We provide RNAi fly stocks that can produce dsRNA by crossing with an appropriate GAL4 driver and knockdown targeted genes (see gAbout RNAi Flyh). You can download a list of full information from the top page gDownload All RNAi Stocks Filesh.



 Q. How can I get a protocol for establishing fly stocks?

A. Please see gAbout RNAi Fly--> Method--> Injection and line establishment--> Fig.2h. Especially, we used w; Sp/SM1; Pr/TM3 double balancer fly for establishing transgenic fly stocks.



 Q. How can I get detailed information on a specific stock?

A. Search the stock ID, ex. 1001R-1, and click the gStock IDh. You will jump to gRNAi Stock Detailh which shows general stock information, vector information, off-target information and so on.



 Q. Is there any white-eyed fly contaminated?

A. Sorry but yes, there are possibilities of white-eyed contamination. White+ is used as a marker but some lines are contaminated with white-eyed flies. They are originated from a failure of balancing caused by multiple insertions. We are trying to cure these lines, anyway please check their eye color before using.



 Q. We found Cy and Sb flies in some stocks.

A. We have established RNAi fly lines with SM1; TM3 balancer chromosome. (w; Sp/SM1, Cy; Pr/TM3, Sb Ser, see About RNAi Fly--> Method--> Injection and line establishment--> Fig.2). Generally our stocks have been cleaned up for the balancers, but sometimes both balancers are left when lethal mutation is caused on the non- P inserted chromosome



 Q. Are there mites in your fly stocks?

A. We cannot guarantee that our stocks are mite free. Please DO NOT mix with your clean stocks before inspection. However, we try keeping our stocks under clean condition and frequent transfers in order to avoid mites. If you find any problems in the stocks you received from us, please contact gflyadmin AT nig DOT ac DOT jph.



 Q. I would like to know DGRC recipe for Drosophila medium.
