Data Examples

Western Blot Detection of Teplizumab antibody by Western Blot. View Larger

Detection of Teplizumab by Western Blot. Western blot shows Daclizumab (negative control), Basiliximab (negative control), Satumomab (negative control), Teplizumab, and Alemtuzumab (negative control). PVDF membrane was probed with 2 µg/mL of Rabbit Anti-Anti- Teplizumab (Anti-Idiotype) Monoclonal Antibody (Catalog # MAB10245) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Teplizumab at approximately 250 kDa (as indicated). Human IgG is shown as a loading control. This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

Background: Teplizumab

The anti-Teplizumab antibody is an anti-Idiotype antibody raised against and selected for the antigenic determinants of the variable region of Teplizumab. 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.
