    Article Snippet: Expression of GST and GST-NRG2_CD bait proteins in the E. Coli host strain BL21(DE3) (Thermo Fisher) was induced with 0.4 mM IPTG (Isopropyl ß-D-1-thiogalactopyranoside) for 4 h at 37 ◦C with shaking.

    Article Title: Rational and Semirational Approaches for Engineering Salicylate Production in Escherichia coli .
    Article Snippet: Salicylate plays a pivotal role as a pharmaceutical intermediate in drugs, such as aspirin and lamivudine.. The low catalytic efficiency of key enzymes and the inherent toxicity of salicylates to cells pose significant challenges to large-scale microbial production.. In this study, we introduced the salicylate synthase Irp9 into an L-phenylalanine-producing Escherichia coli, constructing the shortest salicylate biosynthetic pathway.

    Article Snippet: Materials and methods Prokaryotic cell culture For plasmids replication experiments, Escherichia coli (E. coli) DH5 alpha cells (Invitrogen, CA, USA) were used while prokaryotic protein expression was in E.coli host strain BL21 (DE3) cells (Invitrogen, CA, USA).

    Article Title: Strenuous expression of porcine epidemic diarrhea virus ORF3 protein suggests host resistance.
    Article Snippet: Porcine epidemic diarrhea virus is attenuated upon adaptation to cell culture.. Exclusively genomic mutations have been traced to the ORF3 gene of the laboratory strains.. Previous attempts to express the protein were unsuccessful.

    Cell Culture:

    Article Title: ErpY-LemA: A breakthrough in human leptospirosis diagnosis.
    Article Snippet: Leptospirosis remains a significant public health concern worldwide, particularly in tropical regions, where its diagnosis is often challenging due to nonspecific symptoms and limitations of current diagnostic methods.. In this study, we evaluated the diagnostic potential of the recombinant chimera ErpY-LemA constructed from two Leptospira proteins with known immunogenic properties.. The chimera was successfully expressed in Escherichia coli and demonstrated strong antigenicity, effectively recognizing sera from hamsters infected with diverse Leptospira serovars, indicating its non-serovar-specific nature (P < 0.001).

    Amplification:

    Article Title: Chimeric
    Article Snippet: .. After amplification by PCR, the amplicon (1,122-nt) was cloned into a pET32a expression plasmid (FIG. 1), confirmed by sequencing (Genewiz Inc., Suzhou, China), and subsequently used to transform the Escherichia coli BL21(DE3) host strain (Invitrogen, Carlsbad, CA, USA). .. The transformants were grown in Luria-Bertani (LB) medium (Invitrogen, Thermo Fisher Scientific, Grand Island, NY, USA) containing 100 g/ml of ampicillin at 37° C. with shaking at 250 rpm.
