Figure 2From: XIAP is not required for human tumor cell survival in the absence of an exogenous death signal Dose dependent increase in XIAP knockdown with XIAP siRNA s1455 and s1456. SW620 cells were electroporated with the concentrations of siRNA indicated. After 48 hr, cells were lysed and XIAP levels were monitored by Western blot. A. s1455 B. s1456 C. Quantification by LICOR Odyssey imaging. Percent XIAP levels are expressed relative to the mean of untreated cells.Back to article page
