How do you measure internalization?

To measure internalization, a therapeutic antibody was labeled with a fluorescent tag, pre-bound to target cells and its translocation from cell surface to cytoplasm was monitored by fluorescence imaging. For the purpose of defining the cytoplasmic compartment, cells were stained with a second fluorescent dye.

Are antibodies internalized?

Antibodies against cell surface antigens may be internalized through their specific interactions with these proteins and in some cases may induce or perturb antigen internalization. The anti-cancer efficacy of antibody-drug conjugates is thought to rely on their uptake by cancer cells expressing the surface antigen.

How do you do a FACS analysis?

In a FACS Experiment:

1. Forward-scatter, side-scatter, and fluorescent data is collected, as in conventional flow cytometry.
2. User-defined parameters provide information on how cells should be sorted.
3. Based on these parameters, the FACS machine uses an electrode to impose an electrical charge on each cell.

How to monitor the internalization of an antibody?

When monitoring the internalization of a pHrodo dye–labeled antibody, the increase in pHrodo fluorescence is an effective tool, both for screening antibody candidates when creating new ADCs and for characterizing existing ADCs.
