Individual Autoantibody EIA Profiling

Bio-Rad offers a full range of individual autoantibody EIA assays. The assays feature common protocols, common reagents, color-coded breakaway wells and easy automation, allowing for simple, objective and sensitive autoimmune diagnostics. These assays can be used in conjunction with ANA and ENA screening assays to identify specific autoantibodies associated with autoimmune diseases. Bio-Rad also offers the Kallestad Anti-dsDNA EIA Kit, a quantitative assay with 5 calibrators.
