  • CEN6ARSH4 element from pRS415 (Christianson et al., 1992) was amplified using primers flanked with AatII sites, digested with AatII and cloned into the AatII site of parent vector carrying 256 copies of LacO (Straight et al., 1998).

Addgene cannot verify or guarantee the presence of all 256 copies of LacO. This element is unstable.

For use in two-plasmid-based gene-nuclear periphery tethering assay with either plasmids pAK67 (Addgene #33142).

pVS2 (Addgene #33144) contains 256 LacO repeats and a GAL-GFP-GALpA-reporter gene (pVS1 is identical but does not contain the reporter gene). The reporter was previously characterized and contains a GFP open reading frame flanked by the GAL1 promoter and GAL1 3′ UTR ([Abruzzi et al., 2006] and [Dower et al., 2004]).

pKA67 expresses both LacI-GFP and Nup49-GFP to mark the first plasmid as well as the nuclear periphery with GFP.

Addgene has sequenced a portion of this plasmid for verification. Full plasmid sequence is available only if provided by the depositing laboratory.
