About InVivoSIM anti-sclerostin (SOST) (Romosozumab Biosimilar) This non-therapeutic biosimilar antibody uses the same variable regions as the therapeutic antibody Romosozumab, making it ideal for research use. Romosozumab is a humanized IgG2κ monoclonal antibody that targets sclerostin (SOST), a secreted glycoprotein produced by osteocytes. Sclerostin negatively regulates bone formation by binding LRP4/5/6 and inhibiting Wnt/β‑catenin signaling—a key pathway for osteoblast activity. By neutralizing sclerostin, Romosozumab promotes bone formation while simultaneously suppressing bone resorption. This Romosozumab biosimilar is intended for non-therapeutic research use and can support studies on osteoanabolic mechanisms, Wnt signaling, and sclerostin function in bone biology.
