摘要:
A human antibody or an antigen-binding fragment which binds human IL-6 receptor (hlL-6R) with a KD of about 500 pM or less and blocks IL-6 activity with an IC50 of 200 pM or less. The antibody or antibody fragment binds hlL-6R with an affinity at least 2-fold higher relative to its binding to monkey IL-6R.
