Antibody and antigen-binding fragment compositions targeting cell surface antigens in tumors and methods of use thereof

Abstract

Described herein is an isolated antibody or antigen-binding fragment including a heavy chain variable region including three heavy chain complementary determining regions (HCDRs), wherein the sequence of HCDR1 is GYRLSELS (SEQ ID NO: 1), the sequence of HCDR2 is ISGWDGNT (SEQ ID NO: 2), and the sequence of HCDR3 is ARASGYNY (SEQ ID NO: 3), wherein the isolated antibody or antigen-binding fragment specifically binds human HSP90, specifically HSP90 beta. Also included are detection and therapeutic methods using the isolated antibodies or antigen-binding fragments.

Dependencies are inferred from the claim text.
