In this video, we demonstrate the intracellular radiolabeling of T helper cells using radioactive isotope-conjugated monoclonal antibodies for non-invasive positron emission tomography imaging.
Protocol
1. cOVA-TH1 Cell Radiolabeling NOTE: The 64Cu-DOTA-KJ1-26-mAb will be applied to cultured cOVA-TH1 cells to enable intracellular radioactive labeling. For cOVA-TH1 cell radiolabeling, draw 37 MBq of the radiolabeled 64Cu-DOTA-KJ1-26-mAb in a syringe without dead volume using a dose calibrator. Add 1 mL saline to receive a 37 MBq/mL solution. Suspend cOVA-TH1 cells in the medium at 2 x 106 cells/mL and add …
