A fractionation-based protocol to investigate RNA solubility phase transition during Xenopus oocyte maturation

While RNAs are soluble in vitro, their solubility may be altered when incorporated into some protein complexes inside the cell. The solubility phase transition of RNAs is thus indicative of changes in the function and activity of RNAs. Here, we present a protocol for the assessment of RNA solubility phase transition during Xenopus oocyte maturation. We describe steps for sample preparation, cell fractionation, RNA extraction, real-time PCR, and analysis of the obtained results. For complete details on the use and execution of this protocol, please refer to Hwang et al. (2023).¹
