The mode of lysozyme protein adsorption at end-tethered thiol-terminated polyethylene oxide brushes grafted upon gold was determined in situ by neutron reflectivity using the INTER instrument at target station 2, ISIS, RAL, UK. It was found that the most probable position of protein adsorption at these weakly protein resistive brushes was at the gold-brush interface in the so-called primary protein position.
通过位于英国拉瑟福德阿普尔顿实验室(RAL)的 ISIS 中子源 2 号靶站的 INTER 仪器,利用中子反射率原位测定了溶菌酶蛋白在接枝于金表面的末端连接硫醇基聚环氧乙烷刷上的吸附模式。结果发现,在这些对蛋白质吸附较弱的刷上,蛋白质最可能的吸附位置是在金-刷界面处所谓的主要蛋白质吸附位置。
