Background
Antibody-drug conjugates (ADCs) are targeted cancer treatments consisting of a monoclonal antibody linked to a cytotoxic drug. The antibody targets specific cancer cell antigens, allowing the drug to be delivered directly to tumors while reducing off-target effects.[1] A key step in the mechanism of action (MOA) of ADCs is receptor-mediated endocytosis. After binding to the target antigen, the ADC is internalized, forming early endosomes. These endosomes then mature into late endosomes and lysosomes, where the linker is cleaved to release the cytotoxic drug. The drug then disrupts DNA replication or microtubule function, triggering tumor cell apoptosis or death.[2]
Therefore, screening antibodies with high-efficiency internalization capabilities is critical during early-stage development.

Product List
To support ADC internalization research, we have developed a specialized Antibody Internalization Detection Reagent (Cat. No. IGG-PZF2001), featuring a pH-sensitive red fluorescent dye that labels the human IgG Fc region. The reagent forms a stable fluorescent complex that enables detection of antibody endocytosis within cells. It delivers enhanced fluorescence in acidic compartments with minimal background, supporting flow cytometry, cell imaging, and other cellular analysis techniques.

Applications
Discovery stage: To identify antibodies that not only bind specifically to tumor-associated antigens but also internalize efficiently.
Lead optimization: To evaluate how variations in antibody structure or conjugation chemistry affect internalization and intracellular trafficking.
Preclinical development: To confirm that the selected ADC candidate exhibits consistent internalization behavior across relevant cell models.
Mechanism-of-action studies: To validate the intracellular delivery of the payload and its correlation with cytotoxic effects.

FACS Analysis of Antibody Internalization
FACS Analysis of Antibody Internalization

Anti-CD20 Abs and Human IgG1 isotype control were labeled with Antibody Internalization Detection Reagent (Cat.No.IGG-PZF2001). Raji cells were treated with Anti-CD20 Abs-Internalization Detection Reagent conjugate and Isotype control-Internalization Detection Reagent conjugate separately for 2 hours, then analysis by Flow cytometric. APC signal was used to evaluate the activity (Routine tested).
