Design Philosophy

"In antibody R&D, many routine tasks, such as sequence numbering, physicochemical analysis, and structure retrieval, may look simple, but they often require multiple online tools or custom scripts. We turned these high-frequency workflows into conversational tools so researchers can complete them in natural language."

Protein Information Lookup

Unified protein database search and annotation

Search UniProt ID

Search UniProt entries by protein name and species

Retrieve Protein Information

Retrieve the protein name, function, sequence, and more for a single UniProt ID

Batch Protein Information Retrieval

Retrieve information for multiple UniProt IDs in batch

Retrieve PDB Structure Information

Retrieve PDB structure information for multiple UniProt IDs in batch

Protein Domain Annotation

Retrieve domain information for UniProt proteins and generate visualizations

Protein Concentration Conversion

Unit conversion between molar concentration and mass concentration

Sequence Analysis

Rapid sequence insights for antibody engineering

Multiple Sequence Alignment

Perform global alignment on multiple FASTA sequences, generating alignment plots and identity matrices

Protein Physicochemical Analysis

Calculate molecular weight, isoelectric point, amino acid frequency, and other properties

Antibody Sequence Visualization

Apply IMGT / Kabat / Chothia / Martin numbering to antibody sequences and annotate CDR and FR regions

Structure & Interaction Analysis

AI-powered structure prediction and interaction analysis

Antibody Structure Prediction

Predict antibody 3D structures using ImmuneBuilder (supports VHH nanobodies and full mAbs)

Chai-1 Structure Prediction

Predict structures using the Chai1 model based on user-provided amino acid sequences, including monomeric proteins, multimeric proteins, antigens, and antigen-antibody complexes

Retrieve AlphaFold Structure

Retrieve AlphaFold2 predicted structures by UniProt ID (PDB / CIF format)

PDB Structure Cluster Analysis

Cluster and compare all PDB structures for a given protein

Calculate Structural RMSD

Calculate RMSD between two PDB structure chains

Extract PDB Sequences

Extract chain sequences from PDB files

Interaction Residue Analysis

Identify epitope and paratope residues in protein-protein interactions

PLIP Interaction Analysis

Perform detailed interaction analysis with PLIP and generate visualizations

Antibody Risk Assessment

Identify sequence-level liability sites to reduce development risk

Antibody Liability Site Analysis

Identify deamidation, oxidation, immunogenicity, and other liability sites in antibody sequences

Use Cases

Use Cases and Outputs

Lightweight tools are designed for frequent, short-cycle auxiliary tasks in R&D, such as information lookup, sequence analysis, and structure analysis. Their value is rapid basic-information checks, visualization materials, and clearer inputs for downstream formal service projects.
