The present invention provides antibodies and antigen-binding fragments thereof that specifically bind human proprotein convertase subtilisin/kexin type 9 (hPCSK9) which do not exhibit enhanced binding affinity for hPCSK9 at acidic pH relative to neutral pH. In certain embodiments, the antibodies and antigen-binding fragments of the invention bind hPCSK9 with a lower affinity at acidic pH than at neutral pH.
