From peaks to absolute concentrations within minutes for 100s of metabolites
About Polly QuantFit
Polly QuantFit is a calibration tool used for the absolute quantification of metabolites. For the calculation of absolute concentration, the experiment is done with some standard samples of known concentrations.
1. Intensities are detected in El-MAVEN across all metabolites for all samples
2. This workflow can further be customized as per experimental designs to perform normalization
3. Get mathematical mappings from intensities to concentrations for the standard samples, which are used to calculate concentrations of experimental intensities in Polly QuantFit
4. Generate customized visualizations with Ipythons or a concentration plot used for downstream processing
Polly QuantFit Features
Metadata Creation: This interface detects the standard samples using a machine learning model and then allows adding concentration across all metabolites in a click
Absolute Quantification: Takes the intensity and concentration values for the standard samples and determines the concentration of the biosamples
Reproducibility and Collaboration: Restore your analysis to the exact state of analysis on QuantFit in one click and share that analysis and reports with collaborators
Normalization w.r.t Internal Standard: Concentrations of biosamples are divided by the concentration of the internal standard, to normalize all metabolites
Scaling: Calculated concentrations can be scaled by any factor to neutralize dilution
Custom Visualization: QuantFit shows the biosample concentration plot across all samples as a bar plot. Further, the iPython interface can be used to view custom plots as per defined cohorts
About ThermoFisher Compound Discoverer
ThermoFisher Compound Discoverer software streamlines compound identification, determines real differences between samples and elucidates biological pathways with integrated, powerful software workflows to drive rapid insights from your valuable data.
The node is available for download now.
To guide you through the integration workflow, detailed documentation has been prepared and can be accessed here. The node created in Thermo Compound Discoverer has 3 integrations:
1. MSConvert: It converts .raw data obtained from a mass spectrometer to El-MAVEN accepted formats like .mzML or .mzXML
2. El-MAVEN: For high-quality peak integration in a click using a machine learning model. For better peak integration some parameters have been defined in CD.
3. Polly QuantFit: For absolute quantification of the data. This application is hosted on the cloud on Polly for processing your data
1. Poster: Determining Pharmacokinetics of Cysteamine with Polly QuantFit in collaboration with Shawn Davidson at Princeton University presented at ASMS 2019
2. Poster: Rapid automated absolute quantification of metabolites using Polly QuantFit to understand tumor nutrient availability in collaboration with Matt Vander Heiden Lab at MIT presented at ASMS 2019
3. Quant-inar: A webinar on the Polly QuantFit Workflow to go from peaks to absolute concentrations within minutes for 100s
