Affinity Maturation Pipeline

Discipline: Antibody Engineering | Tools Used: 4 | Servers: 3

Description

Affinity maturation: compute binding affinity, predict mutations, compute hydrophilicity, and predict drug-target interaction.

Tools Used

• ComputeAffinityCalculator from server-28 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/28/InternAgent
• zero_shot_sequence_prediction from server-1 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/1/VenusFactory
• ComputeHydrophilicity from server-29 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/29/SciToolAgent-Bio
• PredictDrugTargetInteraction from server-29 (sse) - https://scp.intern-ai.org.cn/api/v1/mcp/29/SciToolAgent-Bio

Workflow

1. Compute baseline affinity
2. Predict beneficial mutations
3. Analyze hydrophilicity changes
4. Predict improved interactions

Test Case

Input

{
    "sequence": "MKTIIALSYIFCLVFA"
}

Expected Steps

1. Compute baseline affinity
2. Predict beneficial mutations
3. Analyze hydrophilicity changes
4. Predict improved interactions
