Tamm-Horsfall urinary glycoprotein (THP), prepared by salt precipitation of pooled urine from normal individuals, stimulated purified human peripheral blood lymphocytes (PBL) to undergo blastoid transformation. the response was measured by tritiated thymidine uptake into DNA after 6 days in culture. Several batches of THP stimulated, in varying degrees, all samples of PBL tested and the response approached that seen with the mitogens phytohaemagglutinin (PHA), Concanavalin A (Con A) and pokeweed mitogen (PWM) after 4 days in culture. The response usually exceeded that seen after 6 days with tuberculin purified protein derivative (PPD) in Mantoux positive lymphocyte donors.
