RNA co-immunoprecipitation serves as a powerful technique for elucidating the interactions between RNA and RNA-binding proteins, pivotal for understanding posttranscriptional regulation mechanisms. This method captures the dynamics of protein–RNA associations across various cellular processes, applicable to both coding and noncoding RNAs. Here we describe a convenient and compelling method using nanobody coupled beads and UV-crosslinking. Importantly, this method can also be utilized to isolate short-lived complexes, for instance in RNA-degradation. The obtained RNA can be used for many downstream applications, such as qPCR or RNA-sequencing.
