Basic analysis of yeast cells, organelles and derived samples
150.00 €per Sample
Yeast cells, organelles, sub-cellular preparations and derived samples.
Coverage: The basic analysis covers nine of the most important lipid classes:
- PA – phosphatidate;
- PC – phosphatidylcholine;
- PE – phosphatidylethanolamine;
- PG – phosphatidylglycerol;
- PI – phosphatidylinositol;
- PS – phosphatidylserine;
- DAG – diacylglycerol;
- TAG – triacylglycerol;
- EE – ergosteryl ester;
The exact number of discovered lipids provided in results depends on samples.
Analysis:Each sample is extracted, acquired and analyzed once. We recommend to include multiple sample replicates in order to obtain statistically meaningful data.
Approach: Untargeted high-resolution shotgun lipidomics-generated data analyzed using LipotypeXplorer, our proprietary software for identifying all measurable lipids using the molecular fragmentation query language (MFQL) and thus unimpeded by the traditional reliance on predefined spectral databases.
Results: Results are fully quantitative and expressed in absolute values – pmol per sample volume and mol%. The absolute quantification is achieved using lipid class-specific internal standards. Lipotype will provide the data on sample volume analyzed and molar amounts of lipid molecules per sample. Please note: Lipotype will not and shall not be obliged to provide any Lipotype background intellectual property (including Lipotype know-how) or any data incorporating such Lipotype background intellectual property, notably no raw data will be provided.
Structural details:Lipids are reported at the “species” level, meaning that total length, unsaturation and hydroxylations are calculated by summing the properties of the individual fatty acid moieties within a given molecule – e.g. PC 34:2;0 denotes a PC molecule with a total carbon length of 34, 2 double bonds and 0 hydroxylations.
Report: The results are delivered in the form of a Standard Report containing information on methodology, analysis details, used sample amounts, technical variation and quantitative lipidomics results for each sample in tabular format.
Delivery time: The results will be delivered via email within 6 weeks after receiving the properly prepared samples as well as all information regarding the samples and analysis to be performed. The delivery date of samples to Lipotype will be discussed and agreed between the customer and Lipotype. LIPOTYPE’s obligation to perform under this Quotation shall be suspended as long as and to the extent LIPOTYPE is not able to fully and unrestrainedly use its facilities and personnel due to injunctions, restraints, directions or recommendations (individual or public) by any local, national or international governmental or non-governmental institutions (“Authority Measures”), regardless of whether such Authority Measures affect LIPOTYPE, its directors, employees, agents or subcontractors directly or indirectly.
Quality assurance:Each analysis includes internal blank and quality control reference samples to assess and improve the technical quality of the analysis. The technical variation of an analytical run assessed from quality control reference samples is provided within the Report. Please note: No further information or data (especially also including individualized data) on blank and quality control reference samples and/or their analysis will be provided to the customer.
- TheExtended Report containing a graphical presentation of: (a) averaged lipid class values with replicate standard deviations, (b) averaged (sub)species, double bond, chain length and hydroxylation profiles for each lipid class, (c) principal component analysis for un-averaged replicates. The extended report can be viewed via internet browser (as an offline local webpage) or data files can be browsed manually.
- Interactive Data Visualization with LipotypeZoom (available free of charge with the extended data report). LipotypeZoom displays the content of the extended report, is internet-accessible via browser and hosted on a third party platform (shinyapps.io). Lipotype GmbH uploads the results to the third-party platform only having the customer’s consent.
