Key Benefits of iLite Assays

  • Highly specific reporter gene cell lines
  • Very sensitive cell line responses (10 fold inductions)
  • Assay Ready Cells – ready-to-use from the freezer, without culturing of cells
  • Assays within a workday (typically 4-7 hour assays)
  • Normalization gene, which eliminates unwanted matrix effects

Product Description

iLite ADCP Effector Assay Ready Cells are human-engineered cells optimized to express high levels of the low-affinity Fc receptor FcγRIIa (CD32), and the Firefly Luciferase (FL) reporter gene regulated by the NFAT response element. The ADCP reporter bioassay can be used to screen for biologics and other drugs via binding and activation of the FcγRIIa receptor. Normalization of cell counts, serum matrix effects, or lysis of the effector cells by the target cells is obtained by a second reporter gene, a Renilla Luciferase reporter gene construct, under control of a constitutive promotor.

Additional Information

Background


Fc:FcγR interactions are highly involved in antitumor therapy and the mechanism of action is called antibody-dependent-cell-mediated phagocytosis (ADCP) which is mediated by the therapeutic antibody (1).While the antibody is binding to the tumor cell, the Fc portion of the antibody can engage the immune system to destroy the tumor by engagement of Fc receptors for IgG (FcγR) which are expressed by monocytes, macrophages, neutrophils and dendritic cells (1). This is resulting in internalization and degration of the pathogenic cell through phagosome acidification (1). Among the Fcγ-receptors (FcγRIIa, FcγRI and FcγRIIIa) the most important receptor involved in ADCP is FcγRIIa.

The first monoclonal antibody for treating cancer to be FDA approved was Rituximab which in part utilizes the antibody-dependent cellular cytotoxicity (ADCC) and ADCP mechanisms to destroy cancer cells expressing CD20 (2). The majority of therapeutic monoclonal antibodies are generating their effector cell functions by engaging their Fc part and thereby inducing ADCC and ADCP (2,3). Importantly, Fc-engineered antibodies with modulated effector functions to fit specific mechanisms of actions and cancer therapies are generated (3).
