LISA-TRACKER Rituximab is an enzyme linked immunoassay (ELISA) for the quantitative determination of Rituximab (anti-CD20) in human serum samples.

Rituximab is indicated for the treatment of Non-Hodgkin’s Syndrome, Chronic Lymphocytic Leukaemia and Rheumatoid Arthritis in association with Methotrexate in patients with an insufficient response or an intolerance to conventional treatments with disease-modifying anti-rheumatic drugs (DMARDs) or anti-TNF treatments.

Rituximab is a monoclonal antibody directed against transmembrane CD20 molecule expressed on the surface of B-cell (pre-B state to mature B-lymphocyte).  Rituximab is a chimeric antibody constituted with human constant domains (γ1 heavy chain and kappa light chain) and murine variable domains.  During the course of the treatment, some patients can develop antibodies directed against Rituximab.
