Tocilizumab biosimilar uses the same protein sequences as the therapeutic antibody tocilizumab. Tocilizumab is a recombinant humanized monoclonal antibody IL-6 receptor inhibitor used to treat inflammatory and autoimmune conditions. Interleukin 6 (IL-6) is a pro-inflammatory cytokine produced by cells including T-cells, B-cells, lymphocytes, monocytes, fibroblasts. IL-6 rapidly induces C-reactive protein, serum amyloid A, fibrinogen, haptoglobin, and α-1-antichymotrypsin while inhibiting production of fibronectin, albumin, and transferrin. IL-6 also induces antibody production, induces cytotoxic T-cell differentiation, and inhibits regulatory T-cell differentiation. Tocilizumab binds soluble and membrane bound IL-6 receptors, preventing IL-6 mediated inflammation.||Applications: |Suitable for use in ELISA, Neutralization, Functional Assays such as bioanalytical PK and ADA assays, and those assays for studying biological pathways affected by Tocilizumab. Other applications not tested.||Recommended Dilutions:|Optimal dilutions to be determined by the researcher.||Storage and Stability:|May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt.
