Endocytosis and Internalization Potency Detection

An important mechanism of action of therapeutic antibodies is to induce the internalization and turnover of cell surface receptors, leading to receptor down-regulation and antibody endocytosis. This receptor-mediated internalization has shown great potential in various therapeutic or diagnostic applications. Therefore, one of the prerequisites for antibodies designed for antibody-drug conjugates (ADC) is to induce rapid receptor internalization, thereby ensuring cell-specific drug delivery. After internalization, the antibody-receptor complex can circulate back to the plasma membrane or be degraded by late endosomes and lysosomes. CD BioSciences can provide you with professional endocytosis and internalization potency detection service to meet the specific needs of different customers.

Overall solution

  • CD BioSciences currently offers this unique opportunity for our worldwide clients to obtain high-quality service of detecting endocytosis and internalization potencies for lead antibody candidates.
  • CD BioSciences can monitor various processes of cellular uptake and internalization by acidifying the particles or protein conjugates taken up by cells. Particles and proteins enter vesicles through internalization, and these vesicles are acidic relative to the extracellular environment. The use of pH-sensitive fluorescent probes can detect pathway progress and track the entire process from early endosome (pH 6.3) to lysosome (pH 4.7) or recycling.
  • When a cell surface receptor binds to its specific antibody, receptor-mediated endocytosis can be induced. They are often used as a vehicle for targeted delivery of therapeutic drugs, toxins, enzymes, or DNA. CD BioSciences uses a variety of antibody-labeled stains to detect anti-internalization.
