PyChelator

PyChelator calculates free metal ion concentrations in the presence of chelators to support experimental design and quantitative control of metal availability.

Key Features:

• Arbitrary-Precision Calculations: Performs arbitrary-precision arithmetic using Python's built-in Decimal module to minimize rounding errors.
• Stability Constants and Unit Handling: Accepts inputs in smaller units and allows selection from various stability constants or definition of custom stability constants.
• Customizable Chelators and Metals: Includes pre-configured chelators such as EGTA and ATP and metals such as Calcium and Magnesium, while permitting user-defined constants for other chelators and metals.
• Data Export: Outputs calculation results in Excel format.
• Python Integration: Implemented in Python and compatible with Python-based pipelines and workflows.

Scientific Applications:

• Experimental Control of Free Metal Ions: Provides accurate calculations to design and analyze experiments that require precise control of free metal ion concentrations, affecting biological processes and experimental reproducibility.

Methodology:

Implemented in Python, PyChelator builds upon the MaxChelator framework and performs arbitrary-precision calculations using Python's built-in Decimal module.
