Description

Background:
Tocilizumab, also known as atlizumab, is an immunosuppressive drug, mainly for the treatment of rheumatoid arthritis (RA) and systemic juvenile idiopathic arthritis, a severe form of arthritis in children. It is a humanized monoclonal antibody against the interleukin-6 receptor (IL-6R). Interleukin 6 (IL-6) is a cytokine that plays an important role in immune response and is implicated in the pathogenesis of many diseases, such as autoimmune diseases, multiple myeloma and prostate cancer. It was developed by Hoffmann La Roche and Chugai.

Intended Use:
For Estimation of Tocilizumab (ACTEMRA) in human serum and plasma. Please note the kit has not been optimized to be used for any other animal species. Should you require a specific sera tested, please connect with us at sales@krishgen.com for optimization.

Principle:
The method employs the quantitative sandwich enzyme immunoassay technique. Antibodies to Tocilizumab are pre-coated onto microwells. Samples and standards are pipetted into microwells and human Tocilizumab present in the sample are bound by the capture antibody. Then, a HRP (horseradish peroxidase) conjugated anti-Tocilizumab antibody is pipetted and incubated. After washing microwells in order to remove any non-specific binding, the ready to use substrate solution (TMB) is added to microwells and color develops proportionally to the amount of Tocilizumab in the sample. Color development is then stopped by addition of stop solution. Absorbance is measured at 450 nm.
