MetabolomicsMonitoring recombinant protein expression in bacteria by rapid evaporative ionisation mass spectrometry

RATIONALE: There is increasing interest in methods of direct analysis mass spectrometry that bypass complex sample preparation steps.

METHODS: One of the most interesting new ionisation methods is rapid evaporative ionisation mass spectrometry (REIMS) in wh...

MetabolomicsMetabolomic analysis of riboswitch containing E. coli recombinant expression system
In this study we have employed metabolomics approaches to understand the metabolic effects of producing enhanced green fluorescent protein (eGFP) as a recombinant protein in Escherichia coli cells. This metabolic burden analysis was performed against a number of recombinant expression systems and co...

MetabolomicsSystematic analyses of lipid mobilization by human lipid transfer proteins

Lipid transfer proteins (LTPs) maintain the specialised lipid compositions of biological membranes, and many are associated with disease. In eukaryotes, they support organellar functions by transporting lipids between compartmentalised metabolic pathways. However, for the majority of the hundreds...

MetabolomicsRecombinant Production of Biliverdin IXβ and δ Isomers in the T7 Promoter Compatible Escherichia coli Nissle
The ability to obtain purified biliverdin IX (BVIX) isomers other than the commercially available BVIXα is limited due to the low yields obtained by the chemical coupled oxidation of heme. Chemical oxidation requires toxic chemicals, has very poor BVIX yields (<0.05%), and is not conducive to scalab...

TranscriptomicsTranscription profiling of recombinant E. coli to heat-shock and dual heat-shock recombinant protein induction
Recombinant Escherichia coli cultures are used to manufacture numerous therapeutic proteins and industrial enzymes, where many of these processes use elevated temperatures to induce recombinant protein production. The heat-shock response in wild-type E. coli has been well studied. In this study, t...

TranscriptomicsIntroducing synthetic thermostable RNase inhibitors in single-cell RNA-seq
Single-cell RNA-sequencing (scRNAseq) is revolutionizing biomedicine, propelled by advances in methodology, ease of use, and cost reduction of library preparation. Over the past decade, there have been remarkable technical improvements in most aspects of single-cell transcriptomics. Yet, there has b...

TranscriptomicsTranscription profiling of Atlantic salmon cell line SHK-1 exposed to interferon type 1 and interferon gamma for 6 or 24 hours
We have stimulated an Atlantic salmon cell line, SHK-1, with both type I and type II recombinant salmonid IFNs and analysed the transcriptional response by microarray analysis. Cells were exposed to recombinant IFNs for 6 or 24 h or were left unexposed as controls. RNA was hybridised to a 17k feat...

TranscriptomicsTranscription profiling of E. coli high-cell-density recombinant and wild-type
The transcriptome profiles for wild-type (plasmid-free) and recombinant (plasmid-bearing) Escherichia coli during well-controlled synchronized high-cell-density fed-batch cultures were analyzed by DNA microarrays. It was observed that the growth phase significantly affected the transcriptome profile...

ProteomicsInvestigation of the effects on the proteome composition of Escherichia coli producing a recombinant protein in the periplasm under non-optimized and optimized conditions
Recombinant proteins containing disulfide bonds, like antibody fragments, are usually produced in the periplasm of E. coli, because in this compartment of the E. coli cell the formation of disulfide bonds is catalyzed. A recombinant protein is targeted to the periplasm with the help of an N-termina...
