The following stocks express lacZ under the control of gene regulatory sequences within a transgene. This list does not include enhancer trap stocks carrying P{lacW}, P{PZ}, P{lArB}, P{lwB}, P{A92} or some other transgenes expressing lacZ under the control of regulatory sequences near the insertion site.

See beta-galactosidase fusion proteins for stocks with transgenes expressing proteins fused to beta-galactosidase.

Act5C-LacZ.Y503F is a useful tool to measure mistranslation in PheRS-defective background.

Most but not all lacZ-expressing transgenes carried on balancers are included in this list. See the main Blue Balancers page for listings of balancer variants with lacZ transgenes.
