  • Alpha-hydroxy-dihydrosphingosine – AdS
  • Alpha-hydroxy-sphingosine – AS
  • Alpha-hydroxy-phytosphingosine – AP
  • Alpha-hydroxy-6-hydroxysphingosine – AH
  • Cholesterol – Chol
  • Cholesteryl Ester – CE

Analytical Procedure

Each sample is extracted, acquired and analyzed once. We recommend including multiple sample replicates in order to obtain statistically meaningful data.

Analytical Approach

Untargeted high-resolution shotgun lipidomics-generated data analyzed using LipotypeXplorer, Lipotype’s 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.

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.

Description of 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

With the advantage of MS2 fragmentation NdS, NS, NP, NH, AdS, AS, AP, AH and DAG are reported as subspecies (i.e., DAG 16:1;0-16:0;0 – where the first number indicate length of a fatty acid (16), the number behind a colon indicates number of double bonds (1 or 0) and the number behind a semicolon indicates number of hydroxylations (0)). In ceramides the LCB moiety is reported at the first position, followed by the FA moiety (i.e., NS 32:1;2-16:0;0). EOdS, EOS, EOP, EOH, CE and TAG are reported as species. For example, EOS 42:1;2, where 42 is the total number of carbon atoms, the number behind the colon denotes the number of double bonds and the number behind the semi-colon denotes the number of hydroxylations.

Included Reports

Standard 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.

Extended Report:
The Extended Report includes a comprehensive graphical and statistical presentation featuring

  • Lipid Class Analysis (if applicable): 
    Averaged lipid class values, presented with replicate standard deviations, in both raw quantities (pmol) and standardized to the total lipid amount (mol%).
  • Lipid (Sub)species Analysis: 
    Averaged (sub)species data provided in raw amounts (pmol) and normalized to the lipid class total (expressed as mol% of the lipid class).
  • Fatty Acid Profile (if applicable): 
    Averaged fatty acid profiles presented in raw amounts (pmol).
  • Feature Profiles (if applicable): 
    Detailed profiles of double bonds, chain lengths, and hydroxylation for each lipid class, standardized to the total lipid amount of the class (mol% of lipid class).
  • Principal Component Analysis (PCA): 
    PCA performed on un-averaged replicates, with both score and loadings plots provided.

Optional Reports

Correlation Analysis
The Correlation Analysis Report includes an advanced data analysis and contains results of up to 8 pairwise Correlation Analyses. The delivery time for the Correlation Analysis Report will be 3 weeks after the Standard and Extended Report are delivered to the customer. There is one revision round of the Correlation Analysis Report included which can prolong the delivery time. Within this package a continuous parameter describing samples (e.g., age, a clinical parameter, protein expression level etc.) is correlated with amounts of lipid (sub-)species/classes and other data, and includes

  • Correlation analysis with lipid (sub-)species:
    Contains histogram of correlation estimates, their p-values and individual graphical presentation of significant correlations (scatter plots).
  • Correlation analysis with lipid classes and fatty acids:
    Contains sums within classes measured as subspecies. Contains histogram of correlation estimates, p-values and individual graphical presentation of significant correlations (scatter plots).
  • Pathway enrichment analysis (optional):
    Contains an analysis based on the lipid classes of significantly correlating lipid (sub-)species.

Cohort Comparison
The Cohort Comparison Report includes an advanced data analysis and contains results of up to 8 pairwise cohort comparisons. The delivery time for the Cohort Comparison Report will be 3 weeks after the Standard and Extended Report are delivered to the customer. There is one revision round of the Cohort Comparison included which can prolong the delivery time. This package compares two specified groups each containing multiple samples, and includes

  • Cohort Comparison of lipid (sub-)species:

  • Pathway enrichment analysis (optional):
    Contains an analysis based on the lipid classes of the significant lipid (sub-)species hits.

LipotypeZoom
Interactive Data Visualization with LipotypeZoom is available free of charge for 6 months. LipotypeZoom displays the content of the extended report and is internet-accessible via browser. The selection of LipotypeZoom gives consent to Lipotype GmbH to upload the results.

LipotypeZoom PRO
LipotypeZoom PRO is a browser-based interactive tool specifically designed for analysing lipidomics data. It simplifies and streamlines the process and allows you to gain insights from your lipidomics datasets with ease. Using principal component analysis (PCA) and orthogonal partial least squares – discriminant analysis (OPLS-DA), LipotypeZoom PRO gives you a quick overview of your entire project and enables detailed analysis with statistical tests (t-test, Wilcoxon) in paired and unpaired variants. To decipher complex lipid patterns from various lipid structure features such as saturation, chain length and hydroxylation, LipotypeZoom PRO provides you with a fully-fledged enrichment analysis that can be tailored exactly to your needs. Whether you’re interested in KEGG-pathways, Rhea-reactions or feature analysis, we’ve got you covered. What’s more, you can also export plots to share your results with others to speed up decision-making. LipotypeZoom PRO is accessible via internet browser for 6 months after delivery of the results. The selection of LipotypeZoom PRO gives consent to Lipotype GmbH to upload the results.

Delivery Time

The Results will be delivered via email within 6 weeks after receiving the samples prepared according to sample preparation guidelines 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. The selection of Turbo Delivery reduces the delivery time for standard and extended reports of this analysis package to 3 weeks turbo analysis.
