Different sensitivity of CD30+ cell lines to Ber-H2/saporin-S6 immunotoxin.

Abstract excerpt

The in vitro sensitivity of cells to a Ber-H2(anti-CD30)/saporin-S6 immunotoxin has been investigated. The CD30+ cell lines, K562, L428 and L540, were used to study cell binding, uptake and degradation of the immunotoxin. K562 cells were less sensitive than L428 and L540 cells to the immunotoxin by approximately one order of magnitude. The difference in cytotoxicity correlated with the intracellular accumulation...
