Plasmid Preparation:Article Title: Strong preference of BRCA1 protein to topologically constrained non-B DNA structures.
Article Snippet: .. Supercoiled plasmid DNAs of pBluescript II SK (−), and derived plasmids pCFNO [48], pCMYC and pTA50 were isolated from bacterial strain DH5α as described in the QIAGEN protocol (QIAGEN GmbH, Germany). .. XhoI restriction enzyme (New England Biolabs, UK) was used for linearization of plasmids. pCMYC plasmid was constructed by cloning the 141 bp EcoRI/HindIII restriction fragment of pNHE plasmid [49] into the EcoRI/HindIII site of pBSK. pTA50 plasmid was constructed by cloning of (dT)50. (dA)50 sequence, forming a DNA triplex, into the EcoRV site of pBSK.

Article Snippet: .. Supercoiled plasmid DNAs of pBluescript II SK (−) , and derived plasmids pCFNO [ ], pCMYC and pTA50 were isolated from bacterial strain DH5α as described in the QIAGEN protocol (QIAGEN GmbH, Germany) . .. Xho I restriction enzyme (New England Biolabs, UK) was used for linearization of plasmids. pCMYC plasmid was constructed by cloning the 141 bp Eco RI/ Hind III restriction fragment of pNHE plasmid [ ] into the Eco RI/ Hind III site of pBSK. pTA50 plasmid was constructed by cloning of (dT) 50 . (dA) 50 sequence, forming a DNA triplex, into the EcoR V site of pBSK.
Article Title: The central region of BRCA1 binds preferentially to supercoiled DNA.
Article Snippet: BRCA1 is a multifunctional tumor suppressor protein with implications in regulating processes such as cell cycle, transcription, DNA repair, and chromatin remodeling.. The function of BRCA1 likely involves interactions with a vast number of proteins and likewise DNA.. To this date there is only fragmentary evidence about BRCA1 binding to DNA.
