Which assay types are supported?

The server supports UV280 direct absorbance, Bradford, Lowry, and BCA colorimetric assays, as well as custom standard curve regressions.

How do I calculate yield?

The `calculate_uv280_concentration` and `calculate_colorimetric_concentration` tools automatically calculate the total yield by multiplying the mass concentration by the provided total volume.

Can I convert between mg/mL and Molarity?

Yes, use the `convert_units` tool. For mass-to-molar conversions, you must provide the molecular weight of the protein.

More Details Connect to Claude

This MCP server provides specialized tools for quantifying protein concentration and total yield. It implements the Beer-Lambert law for direct UV280 measurements and provides linear regression logic for colorimetric assays like Bradford, Lowry, and BCA. Users can calculate molarity, mass concentration, and total yield from absorbance data or by generating a regression from a set of standard points.
