Abstract

A monoclonal antibody for detecting or capturing an exosome, selected from the group consisting of a monoclonal antibody or antibody fragments thereof that recognize amino acid numbers 113 to 195 of the amino acid sequence as shown in SEQ ID NO: 1, a monoclonal antibody or antibody fragments thereof that recognize amino acid numbers 104 to 202 of the amino acid sequence as shown in SEQ ID NO: 2, a monoclonal antibody or antibody fragments thereof that recognize amino acid numbers 36 to 54 of the amino acid sequence as shown in SEQ ID NO: 3, and a monoclonal antibody or antibody fragments thereof that recognize amino acid numbers 113 to 201 of the amino acid sequence as shown in SEQ ID NO: 3, each capable of detecting or capturing an exosome. The monoclonal antibody for detecting an exosome of the present invention is capable of detecting CD9, CD63 or CD81 on the exosome in a living body with an excellent sensitivity and specificity.
