However, accessing the localized strategies preserving chromatin domain inheritance, specifically the transfer of parental, pre-existing nucleosomes with their associated post-translational modifications (PTMs) during DNA replication, is challenging in living Mar 11, 2020 · The plasmids PX458 (Addgene #48138) 44 and PX333 (Addgene #64073) 45 were linearized using BbsI, or BsaI, restriction enzymes (New England Biolabs, Ipswich, MA, USA) at 37°C for 1hr. The resulting fragments and backbone plasmids were digested with BbsI and ligated using a Quick Ligation Kit (New England Biolabs, Ipswich, MA). BbsI (Thermo Fisher, catalog number: ER1011) 11. The inverted repeat BbsI restriction sites needed to clone the 20-nt guide RNA sequence into pSpCas9(BB)-2A-GFP also oc-curs twice within the Chromatin domains and their associated structures must be faithfully inherited through cellular division to maintain cellular identity. april 2014 21:19:56 UTC+2 je oseba Emma napisala: BbsI has a High Fidelity version BbsI-HF ® that can be stored at -20°C. Single colonies were picked and verified by Sanger sequencing. 1 Plasmid for expression in mammalian cells of FLAG®-tagged catalytically inactive dCas9, for engineered ChIP (enChIP) purification of specific genomic regions. Cis-regulatory DNA is bound and interpreted by protein and RNA complexes and is organized as a 3D structure through long-range chromatin interactions. It works great. 5 μl BbsI for 5 μg of vector). 材料pX458 质粒购自美国Addgene 公司; 质粒抽提及凝胶回收试剂盒均购自 Axygen 公司; EasyPureR Genomic DNA Kit 购自北京全式金生物技术有限公司; DH5α 感受态细胞、 T4 PNK BamHI 和EcoRI 购自Takara 公司; 载体及T4连接酶购自美国Promega 公司; BbsI 核酸内切酶购自NEB 公司; TremeGENE HP BbsI, BsmBI, FokI, VspI restriction endonucleases FPLC fast protein liquid chromatography gRNA guide RNA HDR homology-directed repair IMAC immobilized metal affinity chromatography IPTG isopropyl β-D-1-thiogalactopyranoside KGNK R447G mutant of the NColE7 protein LB lysogeny broth or commonly Luria-Bertani medium LV Lentivirus 1. Cut and dephosphorylate the vector using 2 μl BbsI with 3 μg of vector and fill up to 50 μl reaction volume with ddH 2 O (minimum of 0. NS0 cells were transfected with the pX458 plasmid containing the gRNA sequence using a Lipofectamine 3000 reagent (Thermo Scientific). Find pX330-U6-Chimeric_BB-CBh-hSpCas9 . Ligate to BbsI-cut vector. This plasmid is available through Addgene. While a few NUPs were found to be associated with transcriptionally active genes or regulatory elements (Capelson et al. px458 bbsi
