Fluorescent-Labeled Recombinant Proteins for CAR-T Cells

CAR-T cell therapy is based on the principle that T cells removed from a patient or donor can be genetically engineered to express a specific chimeric antigen receptor (CAR). Once these CAR-T cells are infused back into the patient, the CAR will bind to its specific target antigen on the surface of the patient's tumor cells, activating the T cells, and allowing them to attack and destroy the tumor cells.

Detection of CD19-CAR-T Cells with Recombinant Human CD19 Fc Chimera Atto 647N Protein. CD4+CD8+ T cells were either (A) transduced with a hCD19-CAR or (B) not transduced, and then cultured for 11 days. Cells were stained with a PE-Cy7-CD4 and Recombinant Human CD19 Fc Chimera Atto 647N Protein (Catalog # ATM9269), and detected by flow cytometry
