Taxonomic Hair Proteomics Panel for Forensic Species Identification

A proteomics workflow developed for forensic hair analysis identified 226 taxonomically informative peptides. The panel includes 207 novel peptides and 59 with single-species resolution. The method was validated on single fur-hair samples from 15 species, achieving genus- or species-level classification.

Use Cases

• Forensic evidence prioritization based on species-specific peptide markers
• Developing scalable, automated workflows for hair identification based on mass spectrometry data
• Training machine learning models for taxonomic classification using peptide polymorphism data

Strengths

• Contains 226 taxonomically informative peptides, with 207 novel to this study
• Includes 59 peptides providing single-species resolution
• Method validated on single 20mm fur-hair samples from four individuals per species

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect bias inherent to the 15 species selected based on relevance to crime scene investigation
