Assay type 'Proteomics'

Samples obtained form the central fermentation facility of Sulfosys have been compared using iTRAQ (isobaric tag for relative and absolute quantification). A pilot experiment resulted in creation of SOP and initial data on cells grown at 70 and 80C

Some examples of proteomics templates for Mass Spectrometry data that conform to the MIAPE specification

We use BSA115 strain which lacks RsbU and RsbW proteins. Therefore, there is limited post-transcriptional regulation of sigmaB activity. SigmaB itself is placed downstream of Pspac, inducible by IPTG. The lacZ reporter gene is downstream of Pctc promoter. IPTG concentrations of 0.1, 0.2 and 1 mM are added in mid-exponential phase at an OD of appr. 0.3. The whole experiment runs for about eight hours.

Investigation of all steady state pH-values between pH 5.7 and 4.5 (pH 5.5, 5.3, 5.1, 4.9, 4.7).

For analyzing the binding of CcpA-HPrSer46P-complexes to various cre-elements, Surface Plasmon Resonance was used. All operations were carried out on a Biacore X instrument (Biacore, Uppsala, Sweden). Biotinylated cre DNA was coupled on a Neutravidin coated chip in flowcell two, a biotinylated reference DNA in flowcell one. For visualizing only the interactions of the CcpA-HPrSer46P-complex with the cre elements, CcpA was saturated with 50µM HPrSer46P. Titrations were carried out with 5-100nM ...

Absolute quantification of proteins using heavy labeled QconCAT as an internal standard and quantifying the native proteins in the complex sample via scheduled Multiple Reaction Monitoring(MRM) .

Examples of proteomics templates for gele electrophoresis data that conform to the MIAPE-GE specification

Targeted proteomics for peptides related to fatty acid metabolism. Aim: Check which of these proteins we are able to detect in this experiment.

Protein copy number at 6h, 12h, 24h, 48h, 72h, 96h, average values and SD for the measurements

Plant material The same plant material used for transcriptome analysis in (Flis et al., 2016) was the basis of our proteome study. Briefly, Arabidopsis thaliana Col-0 plants were grown on GS 90 soil mixed in a ratio 2:1 (v/v) with vermiculite. Plants were grown for 1 week in a 16 h light (250 μmol m−2 s−1, 20 °C)/8 h dark (6 °C) regime followed by an 8 h light (160 μmol m−2 s−1, 20 °C)/16 h dark (16 °C) regime for one week. Plants were then replanted with five seedlings per pot, transferred for ...

Proteomics data for N15 incorporation into protein in Ostreococcus grown in 12L:12D light:dark cycles.

Quantitative proteomic analysis of Cyanothece ATCC51142 grown in 12L:12D light:dark cycles, using partial metabolic labeling and LC-MS analysis.

Proteomics data for samples derived from continuous cultures

The soluble protein fraction was subjected to shotgun proteomics (i..e. in-solution digest) applying nanoLC ESI-Iontrap MS/MS and only detections in at least two replicates per condition and bacterium were considered for subsequent analyses. Correspondingly peptide count data was compiled per condition and strain studied.
