Automation of a Homogeneous Proximity Assay for Detection of Residual Protein A in Biological Therapeutics

Agilent Technologies
3 Dec 2014

Protein A is used in affinity chromatography for therapeutic antibody purification and has been shown to leach from columns during purification of antibodies resulting in contamination. Residual Protein A in therapeutic drugs could elicit mitogenic or immunological reactions in patients. This application note demonstrates automation of a HTS compatible homogenous proximity assay for the presence of residual Protein A in biological therapeutics using AlphaLISA technology.

AntibodiesAntibodies are used in techniques such as confocal and fluorescence microscopy, flow cytometry, ELISA, ELISPOT, immunohistochemistry, western blotting and immunopreciptation. Select specific antigen reactivity, high specific affinity, low non-specific binding, monoclonal or polyclonal, primary or secondary antibodies and associated conjugates such as an enzyme or dye for visualization.Microplate Readers / DetectorsMicroplate readers are used to automate the detection and analysis of labeled or label-free components in microplates during assays or live-cell monitoring. Microplate readers are generally distinguished by their mode of detection. Types include absorbance, luminescence, fluorescence intensity, fluorescence polarization, TRF / FRET and multimode microplate readers. Microplate readers deliver a high throughput of samples by reading multiple wells simultaneously, with the 96-well format the most commonly used. As a result, microplate readers are often used in the drug discovery, bioassays, research and pharmaceutical industries for screening applications. Microplate loading can also be automated, with robotic microplate stackers to increase throughput. Find the best microplate readers in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.Plate ProcessingAutomated plate processing is used in microplate technologies for high-throughput, speed and efficiency. Plate processing systems include microplate handlers for moving plates, heat sealers, stackers and carousels for storage, retrieval and delivery, microplate washers and piercers. Useful features of plate processors include walk-away automation, compatibility and easy integration with microplate systems.RegulatoryPharmaceutical regulations impact on all areas of drug development, manufacture and control and supply. Services are provided from the early stages of drug development and clinical trials through to dossier submission, approval and marketing. Regulatory also includes submission of analytical studies from the pharmaceutical product and safety. BiotherapeuticsBiotherapeutics are proteins and other compounds (such as nucleic acids) produced by living organisms that have uses as therapeutics or in <i>in vivo</i> diagnostics. The most well-known example of a biotherapeutic product, and the first to be approved for therapeutic use, was recombinant human insulin.Antibody Arrays
