pGBKT7-Lam is a negative control plasmid that encodes a fusionof the human lamin C protein （a.a. 66–230） and the GAL4 DNA-BD （a.a. 1–147）. The lamin C cDNA insert （GenBank Accession #M13451） was derived from the plasmid referenced in Bar et al. （1993a）. Plasmid modification was performed atBD Biosciences Clontech. Yeast cotransformed with pGBKT7-Lam and pGADT7-RecT, provide a measure of the backgroundthat is due to false-positive two-hybrid interactions. pGBKT7-Lam has not been sequenced.
