PROTEIN RESIDUE ANALYSIS OF TWO STONE TOOL FRAGMENTS FROM THE MUELLER SITE, AZ U:1:307 (ASM), ARIZONA

Two stone tool fragments were recovered from a late Sedentary Hohokam farmstead in the foothills near Cave Creek, Arizona. These tools are similar in shape to previously tested tabular knives used to process agave from floors at sites AZ U:2:73 (ASM), AZ U:2:80 (ASM), and AZ U:2:93 (ASM) in central Arizona; therefore, the two stone tool fragments were tested for the presence of agave proteins using a cross-over immunoelectrophoresis method.

研究人员从亚利桑那州卡韦溪附近山麓地带的一处晚期定居霍霍坎（Hohokam）农耕聚落中发掘出土两件石制工具残片。该残片的形制与此前在亚利桑那州中部AZ U:2:73（ASM）、AZ U:2:80（ASM）及AZ U:2:93（ASM）遗址居住面中发现的、经测试可用于加工龙舌兰的片状刀具高度相似；据此，研究人员采用交叉免疫电泳法（cross-over immunoelectrophoresis）对这两件石制工具残片开展了龙舌兰蛋白残留检测。
