This cell line was obtained by long-term adaptation of the L1210 mouse leukaemic cell line on vincristine and showed an overexpression of P-glycoprotein and accompanying multidrug resistance (MDR) which was defined as a cell resistance to several cytostatics such as vincristine, vinblastine and actinomycin D.
