Aparecium

Aparecium converts fluorescence plate reader and image data into standardized MIDAS-format datasets and exports them for kinetic and equilibrium analysis of ligand binding to G protein-coupled receptors using fluorescence anisotropy.

Key Features:

• Data conversion and integration: Converts proprietary file formats from fluorescence plate readers and images into interoperable formats compatible with MATLAB, GraphPad Prism, and SBToolbox2 (IQMTools).
• Support for fluorescence anisotropy (FA) assays: Processes FA assay data that monitor changes in ligand rotational freedom upon binding to GPCRs to enable analysis of ligand–receptor interactions.
• Budded baculovirus support: Supports experimental setups using budded baculoviruses displaying GPCRs to enable high receptor concentrations and reduced autofluorescence in FA assays.
• Data curation in MIDAS format: Integrates experimental results and metadata into the Minimum Information for Data Analysis in Systems Biology (MIDAS) format for structured data representation.
• Export capabilities: Exports curated datasets to analytical environments for fitting kinetic or equilibrium models.
• Support for diverse probes and assay types: Handles data from multiple fluorescent probes and assay configurations used in ligand–receptor binding studies.

Scientific Applications:

• Screening new active compounds: Enables analysis of ligand binding kinetics and dynamics to support identification of compounds that interact with GPCRs.
• Modeling complex ligand–receptor interactions: Provides standardized datasets suitable for modeling intricate systems of ligand binding and receptor behavior using diverse fluorescent probes and assay types.

Methodology:

Collects kinetic data from fluorescence plate readers with appropriate optical filters; converts proprietary file formats into MIDAS format that integrates experimental results and metadata; and exports processed data for further modeling and fitting of kinetic or equilibrium models.
