Member of large scale dataset(s)
Dfs_BSC_set2

A set of ~800 largely isogenic deficiency stocks created by FLP-induced recombination between FRT-carrying transgenic insertions; molecularly defined deletion endpoints correspond to initial location of the progenitor insertions. Designed to fill gaps in deletion coverage and breakpoint placement; also used to replace older available deficiencies that have not been molecularly mapped.
