Digestion of KG1a lysates.
Time course for the digestion of KG1a lysates with cathepsin G (left panels) or neutrophil elastase (right panels) at a final concentration of 20 μg/mL. Upper panels were immunoblotted with rabbit anti–PSGL-1 N-terminal peptide IgG, and lower panels were immunoblotted with the anti–PSGL-1 monoclonal antibody PL-2. Blots were visualized using the ECL method. Prestained molecular weight markers are myosin (250 kd) and bovine serum albumin (98 kd).
