Immobilized Proteins and Methods and Uses Thereof

摘要

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.

主权项

1. A method of covalently immobilizing a protein, comprising:
a. posttranslationally modifying a cysteine residue of said protein through the addition of functional groups, and b. immobilizing said protein by ligation of said functional groups to a substrate; wherein said protein comprises a soluble protein or a solubilized protein.
