PROTEIN RESIDUE ANALYSIS OF ONE ARTIFACT FROM THE LA PURISIMA MISSION GRANARY SITE, LA PURISIMA MISSION STATE HISTORIC PARK, CALIFORNIA

The mid-section of a chert biface artifact from the La Purisima Mission Granary Site in
Lompoc, California, was analyzed for possible protein residues. This artifact was discovered
near the stone foundation of the La Purisima Granary and is believed to represent a hafted knife
that was used either in agriculture or in skinning hides. Previous studies have shown that protein
residues from a tool's surface can be identified using modified forensic procedures.

本研究针对采自美国加利福尼亚州隆波克市拉普里西马传教站粮仓遗址的一件燧石两面加工石器（chert biface artifact）的中段，开展了蛋白质残留检测分析。该石器出土于拉普里西马粮仓的石质地基附近，据推测为一件装柄小刀，曾被用于农业生产或兽皮剥制工作。既往研究表明，借助改良的法医检测程序，可鉴定工具表面附着的蛋白质残留。
