Tethering of lymphocytes to purified PCLP under flow. (A) MECA-79 Western blotting of the purified PCLP, which was used in the flow chamber experiments, showing a major band at 160 kD. (B) Peripheral blood T lymphocytes or Jurkat T lymphoma cells were infused into the flow chamber at a constant wall shear stress, and the cell tethering rate to the PCLP-coated surface was determined. (C) Immobilized PCLP was treated with OSGE, sialidase, MECA-79, or PCLP mAb (3D3) before infusion of Jurkat cells. Jurkat cells were treated with L-selectin mAb (LAM1-3) or fucoidin before infusion. Error bars represent SD of measurements from at least three separate fields of view.
