[Effect of neuraminidase and proteolytic enzymes on electrophoretic mobility of erythrocytes and their aggregation induced by La(3+)].
The effect of neuraminidase, trypsin and pronase on the electrophoretic mobility of human erythrocytes and their aggregation induced by La3+ was studied in vitro. The aggregation of intact red cells differs from that of cells treated with neuraminidase and proteolytic enzymes. The above differences are observed in the range of La3+ suspension concentration from 20 to 330 microM. A possible mechanism of aggregation is discussed.
