Article Snippet: Recombinant streptokinase variants were expressed in T7 Express lysY E. coli (NEB, Herts, UK) and cells were lysed using B-PER Direct with enzymes (Thermo Fisher Scientific, Loughborough, UK). .. Recombinant SUMO star-streptokinase fusion proteins were purified by Ni-affinity and cleaved with SUMOstar Protease I (Lifesensors) over 4 h (assessed by SDS PAGE) at 30°C in the recommended buffer.

Article Title: Mechanisms of Ca2+/calmodulin-dependent kinase II activation in single dendritic spines
Article Snippet: Protein purification His-tagged mCherry-synapsin 1 peptide (a gift from Dr. Murakoshi) , His-tagged mCherry-CaM and His-tagged calmodulin were cloned into pRSET bacterial expression vector (Thermo Fisher Scientific) and expressed in T7 Express lysY Competent Escherichia Coli (New England BioLabs Inc.), purified with a Ni-NTA column (HisTrap™ HP; GE Healthcare) and desalted with PD-10 column (GE Healthcare). .. The purity of each fraction was confirmed by SDS-PAGE and Coomassie staining.

Plasmid Preparation:

Article Title: Three Mycobacterium tuberculosis Rel Toxin-Antitoxin Modules Inhibit Mycobacterial Growth and Are Expressed in Infected Human Macrophages ▿
Article Snippet: E. coli strain JM109 was used as a host for plasmid constructions (Stratagene, La Jolla, CA). .. T7 Express lysY -competent E. coli cells were used for protein purification (New England Biolabs, Ipswich, MA) and production of whole-cell lysates (WCL) for far-Western analysis.

Article Title: Characterization of the GbdR Regulon in Pseudomonas aeruginosa
Article Snippet: This plasmid is designated pKH10. .. To express the MBP-GbdR fusion protein, pKH10 was transformed into New England BioLabs T7 Express lysY / I q competent E. coli .

Article Title: Scavenging of superoxide by a membrane bound superoxide oxidase
Article Snippet: The expression plasmid pCybB-His was engineered from a GFP-tagged E. coli CybB construct by replacing the GFP moiety with a 8x His-tag, as described previously . .. The new construct was transformed into chemically competent T7 express lysY (New England Biolabs) and grown at 37° C, either in LB supplemented with 25 mg/L kanamycin and 0.01% Antifoam 204 (for non-Se-Met labeled CybB) or in minimal media supplemented with 0.4% glucose, 2 mM MgSO4 , 0.1 mM CaCl2 , 1 μM MnCl2 , 10 μM FeSO4 , 25 mg/L kanamycin and 0.01% Antifoam 204 (for production of selenomethionine labeled protein for structural determination).

Article Title: Envelope stress is a trigger of CRISPR RNA-mediated DNA silencing in Escherichia coli
Article Snippet: For biochemical studies, Cas protein expression vectors were transformed into T7 Express lysY host cells (New England Biolabs) and expression was induced at 15 C for 20 hr with 0.3 mM IPTG. .. After protein binding, the column was washed thoroughly with 100 column volumes of lysis buffer followed by 10 volumes of lysis buffer supplemented with 40 mM imidazole.
