The invention relates to the field of covalently attaching proteins to a substrate, particularly to methods of immobilizing proteins by posttranslationally modifying a cysteine residue of said protein through the addition of functional groups. The invention also relates to biological molecules used in such techniques, including proteins, and detection methods and kits that utilize such immobilized proteins, such as a microdevice or “protein chip”, a high-throughput screening device, and for the microscopy of proteins on a surface.
本发明涉及共价连接蛋白质到基质的领域,尤其涉及通过向蛋白质的半胱
氨酸残基添加功能基团的后翻译修饰方法来固定蛋白质的方法。本发明还涉及用于这种技术的
生物分子,包括蛋白质,以及利用这种固定蛋白质的检测方法和试剂盒,例如微型装置或“蛋白质芯片”,高通量筛选装置,以及用于在表面上显微蛋白质的方法。
