siRNA targeting insulin-like growth factor 1 receptor (IGF-1R)
View Patent ↗Efficient sequence specific gene silencing is possible through the use of siRNA technology. By selecting particular siRNAs by rational design, one can maximize the generation of an effective gene silencing reagent, as well as methods for silencing genes. Methods, compositions, and kits generated through rational design of siRNAs are disclosed including those directed to Insulin-Like Growth Factor 1 Receptor (IGF-1R).
