Description

To increase metabolome coverage and achieve accurate quantification for all detectable metabolites, we use a Chemical Isotope Labeling (CIL) Metabolomics Platform (Zhao et al., 2019, Zhao et al., 2020) for metabolome analysis. The whole metabolome is analyzed by combining the analysis of four submetabolomes: amine/phenol, carboxyl, carbonyl and hydroxyl submetabolome. The combined results from four channels are able to cover 85% to 95% of the entire chemical space of the metabolome. However, a user can choose the labelling method(s) to analyze one or more chemical-group-based submetabolomes, depending on budget and desired coverage. Using one submetabolome analysis, we detect and perform accurate relative quantification of up to 2,500 metabolites (not features) in many different types of samples, including urine, blood, plant extract and cell extracts. Using a combination of four submetabolome analyses, we can cover over 7,000 to 10,000 metabolites (sample dependent) per sample. For the analysis, we will do sample preparation, metabolite extraction, chemical labelling, LC-MS analysis, data analysis, metabolite ID, and statistical analysis (PCA, PLS-DA, Volcano plots). We will provide a summary of our analysis and statistical results. The peak pairs (metabolites) detected, positive or putative IDs, and their relative quantification data will be summarized in an Excel file, which can be used for further analysis such as uploading to MetaboAnalyst for more statistical analysis or pathway analysis.

Service Workflow

TMIC’s Li Node uses a flexible and staged analysis strategy to maximize results and fit all budgets. With global metabolomics profiling, clients may be uncertain about the outcome of the analysis and feel that there is a high investment risk to generate extensive datasets during early stage discovery that may or may not support study goals. We therefore offer a one-channel global metabolomics analysis which allows identification of 2000-3000 metabolites, not features, for $120 CAD per sample. This basic analysis includes results (metabolite identification, accurate relative concentration), and basic statistics, and can be very useful in designing the next stage of global analysis. The basic one-channel analysis is cost effective, and provides useful metabolomics information as is or as the first step towards more comprehensive metabolomics studies. A typical workflow for applying the flexible and staged analysis strategy includes:

  1. Receiving raw samples from a client (e.g., unprocessed urine, plasma, serum, cell pellet, tissue, etc.).
  2. Aliquoting each sample into multiple aliquots, depending on the number of submetabolomes (channels) to be performed and whether global lipidome analysis is also needed.
  3. Using one aliquot for Basic Global Metabolomics Analysis (one channel) (@$120 per sample).
  4. Sending the one-channel analysis report to the client and followed by consultation to discuss results.
  5. Client evaluates the results from the one-channel analysis and makes a decision on:
    1. If the client wishes to continue the analysis of other channels for more comprehensive coverage (e.g., Elevated or Comprehensive Metabolomics Analysis) and/or lipidome analysis, we will continue in this manner. The final cost of the service will depend on the total number of channels analyzed and whether lipidome analysis is performed (refer to price list).
    2. If the client does not wish to proceed with further analysis, only the cost of the one-channel analysis will be invoiced.

 

Platform Strengths

High-coverage accurate relative quantification of metabolites and simultaneous profiling of multiple pathways for discovery or targeted metabolomics.  

 

Metabolite Identification (Tier 1, Tier 2, Tier 3)

Metabolite identification is based on three-tiered ID approach: Tier 1: CIL Library based on accurate mass, RT and peak pairs. Tier 2: Linked Identity Library, high confidence putative identifications (90% accurate) based on accurate mass and predicted RTs. Tier 3: MyCompoundID based on masses.  

 
Example Data (Human serum; other types of samples should give similar results)
Basic Analysis: a total of 2,051 peak pairs or metabolites are detected and relatively quantified with high accuracy. Among them, 532 metabolites are identified with high confidence (Tier 1 and Tier 2) that can be used for pathway analysis. 1,313 metabolites are mass-matched (Tier 3). 206 peak pairs are unidentified or unmatched.
 
Elevated Analysis: a total of 4,196 peak pairs or metabolites are detected and relatively quantified with high accuracy. Among them, 937 metabolites are identified with high confidence (Tier 1 and Tier 2) that can be used for pathway analysis. 2,809 metabolites are mass-matched (Tier 3). 450 peak pairs are unidentified or unmatched.
 
Comprehensive Analysis: a total of 8,196 peak pairs or metabolites are detected and relatively quantified with high accuracy. Among them, 1,483 metabolites are identified with high confidence (Tier 1 and Tier 2) that can be used for pathway analysis. 5,523 metabolites are mass-matched (Tier 3). 1190 peak pairs are unidentified or unmatched.
