Flow cytometric analysis of Human GARP expression on human peripheral blood leukocytes. Human peripheral blood leukocytes were stained with APC Mouse Anti-Human CD41 antibody and either Biotin Mouse IgG2b, κ Isotype Control (Left panel) or SDT Biotin Mouse Anti- Human GARP antibody (Right panel) at 5 μl/test followed by Sav-PE. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software.

Background
GARP, or Glycoprotein A Repetitions Predominant, is a transmembrane protein that acts as a critical docking receptor for latent TGF-β on the surface of activated regulatory T cells and platelets, where its 20 leucine-rich repeats form a horseshoe-shaped solenoid that both stabilizes the cytokine in an inactive conformation and licenses subsequent release through integrin-mediated deformation, thereby positioning GARP as a central checkpoint in immune tolerance and a prime therapeutic target in cancer, autoimmunity and fibrosis.
