▎ 摘　　要

NOVELTY - The application of graphene oxide as protein adsorption dielectric material. USE - Application of graphene oxide as protein adsorption dielectric material (claimed). ADVANTAGE - The method improves the proportion of low-abundance protein species, avoids high-abundance proteins, analyzes interference and influence of low abundance proteins, and prepares graphene oxide easily at low cost, and reduces the cost of separation of proteins. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the separation method of protein, which involves using graphene oxide adsorbing material as adsorptive media containing proteinaceous material and protein, eluting the adsorbed proteins from graphene oxide.
