i-Fect Delivers siRNA in vitro and in vivo

Gene Expression Analysis for Studying Stroke

We have posted over 35 publications that reference use of our i-Fect Transfection Kit to deliver siRNA, miRNA and shRNA in vitro and in vivo. Results documented in these publications prove that this kit is both non-toxic and delivers ultra-high transfection efficiency.

i-Fect Data Example

Figure. The effects of HDAC2 siRNA Infusion into the CeA of P rats on voluntary ethanol consumption as measured by the two-bottle free choice paradigm. Monitoring the voluntary ethanol consumption of alcohol-preferring (P) rats via the two bottle free choice paradigm following infusion of vehicle or histone deacetylase isoform 2 (HDAC2) siRNA into the central amygdala (CeA) demonstrates that high HDAC2 levels may mediate the high alcohol drinking behaviors of P rats. P rats were given access to water and 7% ethanol followed by water and 9% ethanol. On the sixth day of ethanol access P rats received infusion of vehicle or HDAC2 siRNA and consumption of water and 9% ethanol were monitored for sevnfusion. Total fluid intake did not significantly differ between the groups. Values are represented as the mean ± SEM of the ethanol consumption (g / kg / day) and total fluid intake (mL) plotted daily for n=6 rats per treatment group. *Significantly different between the groups.SACHIN MOONAT.

Here's yet another recent publication highlighting use of i-Fect:

In this study data suggest the protective effects of EPO on NUV injuries are highly associated with the increase of p-Cx43, which improves GJIC to reduce neurotoxic substances: Ziyi Zhoua, Xiaobai Weib, Jun Xiang, Junpeng Gao, Lixin Wang, Jinsong You, Yefeng Cai , Dingfang Caid. Protection of erythropoietin against ischemic neurovascular unit injuries through the effects of connexin43. Biochemical and Biophysical Research Communications. doi:10.1016/j.bbrc.2015.02...The strands were incubated at 90°C for 5 min and then at 37°C for 1 h. SiRNA was prepared immediately before administration by mixing the RNA solution (1 μg/μl in annealing buffer) with the transfection reagent i-Fect (v/v: 1/3; Neuromics, Edina, MN, USA) to a final siRNA ...

•EPO has protective effects on ischemic NVU injuries.
•EPO up-regulates phosphorylation of Cx43, not total Cx43.
•EPO's protective effects on NUV injuries are p-Cx43-GJIC dependent.
