Novel Fc Effector Function Reporter Bioassays from Promega for Development of Therapeutic Antibodies

10 Apr 2016

This poster discusses the development of a suite of Fc receptor-specific reporter bioassays to interrogate antibody-dependent cellular cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP) mechanisms of action. Drug developers and regulatory authorities recognize ADCC and ADCP as important mechanisms of action of therapeutic antibodies (Abs). In qualification studies, the Fc effector reporter bioassays exhibit excellent specificity, accuracy, precision, and linearity enabling their use in Ab characterization, optimization, and potency determination.

ONE-Glo™ Luciferase Assay System

Promega Corp.

The ONE-Glo™ Luciferase Assay System provides a highly sensitive, robust, homogeneous assay for detection of firefly luciferase reporter gene expression in mammalian cells. Ideally suited for high- and ultrahigh-throughput applications, the ONE-Glo™ Assay contains a new luciferase substrate, resulting in a reagent that is more stable, more tolerant to sample components, and has less odor than standard luciferase assay reagents. These features ensure that the ONE-Glo™ Assay provides robust performance and also eliminates many of the handling inconveniences experienced using other reporter assays in a high-throughput setting. Features - Benefits Simplify Your Assay Optimization: The robust performance, reduced odor, improved storage, and larger available sizes make assay optimization even easier and more efficient. Store at Room Temperature or at 4°C: The extended stability of the ONE-Glo™ Reagent at room temperature and 4°C makes it more convenient for everyday use. Improve Assay Precision: Because the ONE-Glo™ Reagent is less sensitive to mixing and dispensing conditions, reproducibility is enhanced. The assay is ideal for use in high-density (384- and 1536-well) microplates. Get a Brighter, Longer-Lasting Signal: Optimized for batch and continuous-process handling, the extended bright light output of the ONE-Glo™ Assay allows high sensitivity, especially when extended incubation is required prior to reading results. Reduce Unwanted Effects from Sample Components: The novel chemistry used in the ONE-Glo™ Assay is less sensitive to culture media, phenol red, and luciferase inhibitors than other luciferase assays.

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.MicroplatesMicroplates are multi-well plates used to increase the throughput of biological investigations. The number of wells microplates contain can range from 6 to 3243 wells, with the 96-well format being the most commonly used. Microplates can come tailored for a range of applications including cell culture, PCR, filtration, storage, non-binding surface, protein crystallization, as well as pre-coated, deep well and normal Standard microplates. Additionally, options for microplate colors include clear , black, white or black with clear bottom and white with clear bottom for absorbance microplate reader applications.
