Figure 3From: The siRNA targeted to mdr1b and mdr1a mRNAs in vivosensitizes murine lymphosarcoma to chemotherapy The sensitivity of RLS 40 cells to vinblastine. The viability of RLS40 cells transfected with control luciferase siRNA (100 nM) or mdr1b/1a siRNA (100 nM) was measured by MTT-test 48 h after incubation with vinblastine.Back to article page
