Silencing Cytokines in-vivo with i-Fect

Knocking Down Cytokine to Study Pain ResponseWe have many unique applications published from researchers using our Transfection Kits in vitro and in vivo. Here researchers simultaneously 3 immune/inflammatory response cytokines in vivo: Byung Moon Choi, Soo Han Lee, Sang Mee An, Do Yang Park, Gwan Woo Lee, and Gyu-Jeong Noh. The time-course and RNA interference of TNF-α, IL-6, and IL-1β expression on neuropathic pain induced by L5 spinal nerve transection in rats. Korean J Anesthesiol. 2015 Apr;68(2):159-169. English. Published online March 30, 2015. http://dx.doi.org/10.4097/kjae.2015.68.2.159.Protocol: RNAs were administered as described, with modifications [11]. A cocktail of siRNA simultaneously targeting TNF-α (Silencer® Select siRNA; s128522, Ambion, Austin, TX, USA), IL-6 (Silencer® Select siRNA; s217844, Ambion, Austin, TX, USA) and IL-1b (Silencer® Select siRNA; s127941, Ambion, Austin, TX, USA), as well as a control siRNA (Silencer® Negative Control #1 siRNA; Cat #4635, Ambion, Austin, TX, USA), were prepared immediately prior to administration by mixing the RNA (200 µM) with the transfection reagent, i-Fect™ (Neuromics, Minneapolis, MN, USA), in a ratio of 1 : 5 (w : v). At this ratio, the final RNA/lipid complex concentration was 2 µg in 5 µl for each cytokine siRNA and 6 µg in 15 µl for the control siRNA. The cytokine siRNAs were combined and they and the control siRNA (15 µl each) were delivered to the lumbar region of the spinal cord vi...
