Article Title: Direct Interaction of Selenoprotein R with Clusterin and Its Possible Role in Alzheimer’s Disease

doi: 10.1371/journal.pone.0066384

Figure Lengend Snippet: Plasmids carrying on the fetal brain cDNA library were co-transformed into the NpGBKT7- SelR′ -containing yeast and screened by the selection plate for the blue colonies (A). The interaction between SelR′ and Clu was verified by re-transformation of the plasmids NpGBKT7- SelR′ and pACT2- Clu into either AH109 (B) or Y2HGold (C) yeast cells. Yeast cells in B (1–3) were transformed with single NpGBKT7- SelR′ , NpGBKT7- SelR′ plus pACT2, and NpGBKT7- SelR′ plus pACT2- Clu plasmids, respectively. Yeast cells in C, D, E were transformed with NpGBKT7- SelR′ plus pACT2- Clu , pGBKT7- p53 plus pADT7- T (positive control), and pGBKT7- Lam plus pADT7- T (negative control), respectively, followed by the selection on SD/−Leu/−Trp/X-α-Gal/Aba plates.

Article Snippet: Matchmaker™ Gold yeast two-hybrid system, yeast strains Y2HGold and AH109, plasmids pACT2 and NpGBKT7, and human fetal brain cDNA library (using pACT2 as the vector) were purchased from Clontech Laboratories (Mountainview, CA, USA).
