The present disclosure relates to an antibody or an antigen-binding fragment thereof specifically binding to GRP94, and uses thereof. A GRP94 antibody or antigen-binding fragment thereof according to the present disclosure has very high specificity and affinity to GRP94, and excellent growth-inhibiting, infiltration-inhibiting, and angiogenesis-inhibiting effects on colorectal cancer cell lines, and thus can be useful as a composition for treating cancer, inhibiting cancer metastasis, and inhibiting angiogenesis.

Antibody specifically binding to GRP94 or antigen-binding fragment thereof, and uses thereof

The present invention relates to a monoclonal antibody that specifically binds to vascular cell adhesion molecule-1 (VCAM-1 or CD106). Specifically, the present invention relates to an antibody that specifically binds to both human and mouse vascular cell adhesion molecule-1 (VCAM-1), a method for producing the same, a composition for diagnosis or treatment comprising them and a method for diagnosis or treatment using them. The monoclonal antibody of the present invention is the first recombinant monoclonal antibodies that is specific to human and mouse VCAM-1. In addition, the monoclonal antibody of the present invention shows a strong affinity to VCAM-1 expressed in rat skeletal muscle and porcine endothelial cells as well as human and mouse endothelial cells and is found to strongly inhibit the interaction between leukocytes and activated endothelial cells. Accordingly, the monoclonal antibody of the present invention can inhibit a VCAM-1 mediated adhesion of leukocytes to endothelial cells and potently treat VCAM-1 mediated disease, especially inflammatory disease or cancer.
