iLite® CD20 (+) Target

Product Overview

iLite® Target CD20 (+) Assay Ready Cells are designed to enable determination of the ADCC and ADCP activity of existing or new anti-CD20 drug candidates.

iLite Target CD20 (+) Assay Ready Cells are based on a human B lymphocyte cell line, Raji (ATCC# CCL-86), and have been genetically engineered and optimized to express high and constant levels of the surface antigen CD20.

The cells are to be use as target cells for measuring the ADCC and ADCP activity of anti-CD20 antibodies and are optimized to give high sensitivity and specificity when used together with iLite ADCC and ADCP Effector Assay Ready Cells.

How it works

Principle of iLite® ADCC and ADCP Bioassays

Principle of iLite® ADCC and ADCP Bioassays

Our two-cell ADCC or ADCP bioassays consist of target cells expressing the antigen under study and effector cells closely resembling the natural FcγRIIIa (for ADCC) or FcγRIIa (for ADCP) signal transduction pathway. Target control cells that do not express the antigen are also available. The effector cells contain two luciferase genes: an inducible Firefly luciferase gene and a constitutively expressed Renilla luciferase gene used for control purposes.

Principle of iLite® ADCC and ADCP Bioassays

Principle of iLite® ADCC and ADCP Bioassays

A therapeutic antibody can bind to its antigen on the target cell surface. The fc-region of the antibody can bind to the FcγRIIIa (ADCC) or FcγRIIa (ADCP) receptor on the effector cells.

Principle of iLite® ADCC and ADCP Bioassays

Principle of iLite® ADCC and ADCP Bioassays

The antibody binding to the target and effector cells triggers a signal pathway in the effector cell, activating the Firefly luciferase gene. The strength of the resulting luciferase luminescence correlates with the antibody’s ability to activate ADCC or ADCP.
