The anti-Rituximab antibody is an anti-Idiotype antibody raised against and selected for the antigenic determinants of the variable region of Rituximab. The antibody has been tested against a broad range of other biosimilars to ensure specificity. This highly specialized anti-idiotypic antibody can be used in a variety of pharmacokinetic (PK) assay formats. In addition to Rituximab, the anti-Idiotype antibody also detects derivatives of Rituximab (Ibritumumab and Tositumumab).
