Thymocyte differentiation antigen 1 (THY1) functions in juxtacrine signaling.
THY1 and its ligand are expressed in the anterior lobe of the rat pituitary gland.
THY1 is a novel specific marker of thyrotropes, which produce TSH.
THY1 antibody-mediated purification yields 83% thyrotrope purity (17-fold enriched).
The THY1 antibody/pluriBead-cascade cell isolation system is rapid and convenient.
