About InVivoSIM anti-human RANKL (CD254) (Denosumab Biosimilar) This non-therapeutic biosimilar antibody uses the same variable regions from the therapeutic antibody Denosumab making it ideal for research use. This Denosumab biosimilar reacts with human RANKL (receptor activator of nuclear factor kappa-B ligand) also known as CD254 and TRANCE (TNF-related activation-induced cytokine). RANKL is a 35 kDa type II membrane protein that belongs to the TNF superfamily. RANKL is expressed on activated T lymphocytes in the lung, thymus, and lymph nodes and on osteoclasts. RANKL has been implicated in the regulation of T cell and dendritic cell interactions as well as osteoclast differentiation. Additionally, RANKL was found to be critical for osteoclast differentiation. Denosumab is an inhibitor of RANKL which functions by decreasing the development of osteoclasts.
