An antibody against human programmed cell death protein (PD-1) or an antigen-binding fragment thereof, a nucleic acid encoding the same, a vector containing the nucleic acid, and a recombination transformed with the vector Provided are a microorganism, a method for producing the antibody or antigen-binding fragment thereof, and a composition for preventing or treating cancer comprising the same. Since the novel antibody or antigen-binding fragment thereof that binds to PD-1 of the present invention can bind to PD-1 and suppress its activity, it is useful for the development of immunotherapeutic agents for various diseases related to PD-1. It is. [Selection] Figure 1 |
