The following information accompanied stocks donated to the Bloomington Stock Center by Ken Irvine, Rutgers University (11/06). In P{UAS-beta4GalNAcTA.I}, the beta4GalNAcTA gene (FBgn0027538) is expressed under UAS control. In P{UAS-beta4GalNAcTB.I}, the beta4GalNAcTB gene (FBgn0039625) is expressed under UAS control. P{UAS-beta4GalNAcTA.I}1.2 is a homozygous viable and fertile, third chromosome insertion. P{UAS-beta4GalNAcTA.I}1.4 is a homozygous viable and fertile, second chromosome insertion. P{UAS-beta4GalNAcTB.I}1.2 is a homzygous and hemizygous viable and fertile, X chromosome insertion. P{UAS-beta4GalNAcTB.I}5.1 is a second chromosome insertion.
