Demonstrate Antibody ADCP Activity Through FcγRI

Fc receptor-mediated antibody-dependent cell-mediated phagocytosis (ADCP) is an important mechanism of action (MOA) of therapeutic antibodies designed to recognize and mediate the elimination of virus-infected or diseased (e.g., tumor) cells. Unlike antibody-dependent cell-mediated cytotoxicity (ADCC), which is mediated primarily through FcγRIIIa expressed on NK cells, ADCP can be mediated by monocytes, macrophages, neutrophils and dendritic cells via FcγRIIa, FcγRIIIa and FcγRI. All three receptors can participate in antibody recognition, receptor clustering and signaling events that result in ADCP.

Current methods used to measure ADCP rely on the isolation of primary human monocytes, ex vivo differentiation into macrophages and measurement of target cell engulfment. These assays are laborious and highly variable due to complex assay protocols and unqualified assay reagents. As a result, these current methods are difficult to establish in quality-controlled, drug development settings.

The FcγRI ADCP Bioassay is a bioluminescent cell-based assay for measuring the potency and stability of antibodies and other biologics with Fc domains that bind and activate FcγRI. The assay consists of a genetically engineered Jurkat T cell line that expresses the high-affinity human FcγRI and a luciferase reporter. The bioassay workflow is simple, robust, consistent and overcomes many of the limitations of traditional methods.

Product Formats and Components

Core Kits (Cat.# GA1341, GA1345)

  • Includes FcγRI Effector Cells, Cell Culture Medium and Assay Reagents.
  • Recommended for routine use with customer-defined antibody and target cells.
  • Available in 1X and 5X sizes.

Cell Propagation Model (Cat.# GA1332)

  • Includes the FcγRI Effector Cells (CPM); these are cryopreserved cells that can be thawed, propagated and banked for long-term use.
  • Use with Bio-Glo™ Luciferase Assay System.

Cell Bank Format (Cat.# GA1330)

  • Available for customers who are planning to expand the CPM vials, but the expansion is done by Promega scientists.

Workflow

Standard bioassay workflow with cultured cells
Improved bioassay workflow with thaw-and-use cells

Standardized Reagents Improve Results

  • Thaw-and-use format provides significant time and labor savings over traditional methods while reducing variability.
  • Easily amenable to high-throughput workflows.

Assay Principle

The FcγRI Effector Reporter Bioassays use an alternative readout from traditional primary cell-based assays. Primary cells are replaced with a Jurkat cell line stably expressing human FcγRI and response element (RE)-mediated activation of luciferase activity in the effector cells.

Representation of the FcγRI ADCP Reporter Bioassay. The bioassay consists of a genetically engineered cell line (FcγRI Effector Cells), an antigen expressing target cell and an antigen-specific antibody. When all components are cocultured, the antibody simultaneously binds target cell antigen and FcγRI receptors on the surface of the effector cells. This results in receptor clustering, intracellular signaling and luciferase activity.

Assay Performance Data

Representative data for the FcγRI ADCP Reporter Bioassay.

Representative data for the FcγRI ADCP Reporter Bioassay. Panel A. FcγRI ADCP Bioassay Effector Cells were treated with serial dilutions of Control Ab, Anti-CD20, and infliximab (anti-TNFα) in the presence of Raji target cells. Panel B. FcγRI ADCP Bioassay Effector Cells were treated with serial dilutions of Control Ab, Anti-CD20, in the presence or absence of Raji target cells. Data were generated using thaw-and-use cells. Luciferase activity was quantified using Bio-Glo™ Reagent, and plates were read on a GloMax® Discover System. Data were fitted to a 4PL curve using GraphPad Prism® software.
