The primary antibodies used in the present study were against the following antigens: RANKL (rabbit polyclonal antibody, dilution 1 : 1000, Proteintech), OPG (rabbit polyclonal antibody, dilution 1 : 300, Abcam, Cambridge, MA, USA), and β-actin (internal control, rabbit polyclonal antibody, dilution 1 : 5000, Abcam). Proteins from the knee joint were separated using SDS-PAGE then transferred to polyvinylidene difluoride membranes. The intensity of each protein was normalized using β-actin and expressed as a proportion of the control. Analysis of Western blots was performed in accordance with a previous study [21 (link)].
