Case Study: Reagent Antibodies for Evaluation of Drug Levels and Activity in Patient Sera

Antibodies for Detection and Neutralization of Biotherapeutics

There is a need for antibodies in pre-clinical and clinical studies for the detection of potential biotherapeutic antibodies (Th-Mab) and also for the blocking of the therapeutic to its specific ligand target (anti-idiotypic/neutralizing (anti-ID Nab)).

As there is a potential for adverse effects on the animal’s immune system from either the active drug-antigen and/or resulting circulating antibody during the immunization phase, specifically designed immunization protocols are used to abrogate potential adverse effects.

Case Study 2: Reagent Antibodies for Evaluation of Drug Levels in Patient Sera

Antibodies Specific for Parent Small Molecule Drug Over Potential Metabolites

Mice were immunospressed with the metabolite (oxide form of the drug) and then challenged with the parent drug. Following fusion, clones producing specific antibody to the parent drug were selected over clones producing antibodies to the metabolite. An ELISA was then developed using the parent drug specific antibody to detect drug in patient sera samples.
