摘要

1/1 summary “isolated antibody or antigen-binding fragment thereof, isolated nucleic acid, host cell, method of assaying a tissue sample removed from a human for expression of pd -l1, case, and composia ‡ RECTIFIER antibody comprising a mixture of cells anticorpoâ spring ‰ £ € the revelation the present provides isolated antibodies that specifically bind to human PD-L1, as well as fragments liga㧠antigen binding of such antibodies, and kits comprising anti-pd-11 antibodies or binding fragments and a set of reagents for detecting an antibody complex, or antigen binding fragment thereof, bound to human pd-11. The antibodies and antigen binding fragments of this disclosure are used for immunohistochemical detection of human pd-1 expression in tissue samples. Nucleic acid molecules encoding the antibodies and antigen-binding fragments of this disclosure are also provided, as well as expression vectors and host cells for expression of these.
