Microinjection of dsRNA into Fully-Grown Mouse Oocytes: Figure 1.

Abstract

INTRODUCTIONRNA interference (RNAi) is a suitable method for sequence-specific post-transcriptional gene silencing in a number of model systems. The following protocol describes delivery of a double-stranded RNA (dsRNA) of choice into fully-grown, germinal vesicle-intact (GV) mouse oocytes by microinjection. Microinjected oocytes can be cultured for up to 2 d or they can be matured to metaphase II. The metaphase II eggs can be fertilized in vitro and cultured up to the blastocyst stage. The efficiency of knockdown by RNAi can be assayed by quantitative reverse transcriptase (RT)-PCR (qPCR).
