Figure 1: TNF-a serum levels of TIMP-3-treated rats compared to salinetreated rats exposed to liver I/R injury. Rat blood samples were allowed to clot to isolate serum. Serum samples were quantified for TNF-a by ELISA as per manufacturer’s protocol. TNF-a levels on the Y-axis (pg/ml) are shown for TIMP-3-treated rats and saline-treated rats prior to ischemia/reperfusion injury. The X-axis indicates the length of reperfusion time for TIMP-3-treated and saline-treated rats.
