## Description

This MCP server provides specialized tools for designing protein purification workflows. It allows users to calculate precise parameters for different separation modes. Use `design_affinity_capture` to determine column volume and elution strategies for affinity-based steps. Use `design_ion_exchange` to select resins and buffer conditions based on protein charge. Use `design_size_exclusion` to calculate column dimensions for polishing steps. Finally, use `evaluate_purification_protocol` to aggregate all design data into a complete feasibility assessment.

## Tools

### design_ion_exchange
Determines buffer conditions and resin selection for charge-based separation

### evaluate_purification_protocol
Aggregates all design parameters to provide a final feasibility assessment

### design_affinity_capture
Calculates optimal column volume and elution strategy for affinity-based purification

### design_size_exclusion
Calculates column dimensions for polishing steps based on molecular weight

## Prompt Examples

**Prompt:** 
```
Help me design an affinity capture step for 5 grams of protein using a resin with 20 g/L capacity and high affinity, with 10 grams of impurities.
```

**Response:** 
```
The required column volume is 0.25 liters, and the recommended elution buffer is a high-salt gradient to ensure efficient detachment.
```

**Prompt:** 
```
Calculate the column dimensions for a size exclusion polishing step with a 200,000 Dalton protein and a 5 liter sample volume, requiring 0.8 resolution.
```

**Response:** 
```
The recommended column diameter is 15.0 cm with a bed height of 20.0 cm, operating at a flow rate of 0.5 L/min.
```

**Prompt:** 
```
Determine the buffer conditions for a protein with a pI of 5.2 using a buffer at pH 7.5 and medium salt tolerance for 2 grams of protein.
```

**Response:** 
```
An Anion Exchange resin is required. The optimal buffer pH is 7.5, and the required salt concentration is 0.15 M.
```

## Frequently Asked Questions

**How do I design an affinity chromatography step?**
You can use the `design_affinity_capture` tool by providing the target protein mass, resin binding capacity, ligand affinity strength, and impurity load.

**Can I assess the entire purification process at once?**
Yes, once you have completed individual designs for affinity, ion exchange, and size exclusion, you can use `evaluate_purification_protocol` to get a final feasibility score and summary.

**What information is needed for ion exchange design?**
To use `design_ion_exchange`, you need the protein's isoelectric point, the target buffer pH, the salt tolerance, and the target protein mass.
