Scientific Data

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

Detection of Gemtuzumab by Western Blot. Western blot shows Centuximab, Rituximab, Brentuximab, and Gemtuzumab biosimilars. PVDF membrane was probed with 0.5 µg/mL of Anti- Gemtuzumab (Anti-Idiotype) Monoclonal Antibody (Catalog # MAB9617) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). A specific band was detected for Gemtuzumab at approximately 240 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Immunoblot Buffer Group 1.

Specificity of Anti-Gemtuzumab (Anti-Idiotype) Antibody in ELISA Capture Assay. Biotinylated biosimilars were serially diluted and incubated with Anti-Gemtuzumab (Anti-Idiotype) Antibody (Catalog # MAB9617, green line) coated at 1 μg/mL on a 96-well polystyrene plate. No cross-reactivity with Rituximab (black line) or biotinylated IgG control (orange line) was observed.

Specificity of Anti-Gemtuzumab (Anti-Idiotype) Antibody in Direct ELISA. A panel of biosimilars was coated at 1 μg/mL in 96-well polystyrene plates. Anti-Gemtuzumab (Anti-Idiotype) Antibody (Catalog # MAB9617, 333 ng/mL) detected Gemtuzumab. No cross-reactivity with Cetuximab, Ibritumomab, Rituximab, Adalimumab, Tositumomab, Brentuximab, Trastuzumab, Solanezumab, Teprotumumab, and Aducanumab was observed.

Background: Gemtuzumab

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