摘要
A highly sensitive method of detecting GASP-1 or a fragment thereof in a sample is provided. The method comprises (a) exposing a surface to a sample comprising GASP-1 or a fragment thereof; (b) immobilizing an anti-GASP-1 detection antibody to the surface; (c) measuring the amount of the anti-GASP-1 detection antibody immobilized to the surface; and (d) determining the presence of the GASP-1 or a fragment thereof in the sample based on the amount of the anti-GASP-1 detection antibody immobilized to the surface. A coating agent may be immobilized to the surface in step (a), and the anti-GASP-1 detection antibody may be immobilized to the surface via the coating agent, directly or indirectly. The coating agent may be selected from the group consisting of a first GASP-1 fragment, a conjugate of a protein (e.g., bovine serum albumin (BSA)) and a GASP-1 peptide, a capture antibody against a microvesicle or exosomal surface biomarker, a capture antibody against a second GASP-1 fragment, and a combination thereof. Also provided are kits for detecting GASP-1 or its fragment.
