Internalization Assay

Internalization Assay Overview

Monoclonal antibodies are currently widely utilized in therapies for cancer, inflammation, and antiviral diseases. An important property of antibodies is the extent, location, and speed of their cellular internalization. Antibody-Drug Conjugates (ADCs) consist of a chemical link that connects a bioactive cytotoxic drug to a monoclonal antibody. Monoclonal antibodies (MABs) serve as carriers to deliver small molecule drugs to target cells. Once bound to the cell surface antigen, the internalization of the MAB allows the small-molecule drug to enter the target cell and exert its toxic effects. The ability of an antibody to internalize is a critical indicator for the early screening of ADC drugs.

In ADC research, efficient, stable, convenient, and high-throughput methods for antibody internalization assays are needed. Kyinno offers comprehensive internalization assays based on different assay kits, such as the Fab-zap Internalization kit, pH-rodo dye, αHFc-CL-MMAF Internalization kit, and target stripping method.
