most extensive series of protein alterations on transformed cells was detected by two-dimensional electrophoresis of cell surface proteins radiolabeled by lactoperoxidase catalyzed radioiodination : a fibronectin-like 220k protein with two isoelectric forms ( pi 5.9 and 6.2-6.6 ) , a 180k protein of pi 6.2-6.6 and two proteins of 48k and 50k with pi approximately 5.4-all decreased on examined transformed cells .
