[Serum proteins in human skeletal remains]

Area of Science:

• Biochemistry
• Paleoproteomics
• Immunology

Context:

• Analysis of ancient human remains provides insights into past populations.
• Non-collagenous proteins offer unique molecular information.
• Peruvian archaeological sites yield valuable skeletal material.

Purpose:

• To characterize non-mineral-bound, non-collagenous proteins from ancient Peruvian bones.
• To investigate the potential presence and nature of polymorphic serum proteins in ancient bone samples.
• To establish methods for specific protein identification in archaeological contexts.

Summary:

• Electrophoretic techniques, including SDS-polyacrylamide-electrophoresis and isoelectric focusing, were employed to analyze proteins extracted from ancient Peruvian human bones.
• Results demonstrated distinct molecular weight bands and pH-gradient distributions, suggesting the presence of complex protein mixtures.
• These findings indicate a potential connection to polymorphic serum proteins, which could be further identified using immunological approaches.

Impact:

• This study advances paleoproteomic methodologies for analyzing ancient biomolecules.
• The findings contribute to understanding ancient Peruvian population genetics and health through protein analysis.
• Establishes a foundation for using immunological techniques in the identification of specific proteins in ancient skeletal tissues.
