This video demonstrates the enhanced crosslinking immunoprecipitation (eCLIP) method for identifying RNA-binding proteins in mouse testis. eCLIP enables the precise identification of binding sites where RNA-binding proteins (RBPs) interact with their target RNAs.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Tissue Harvesting and UV Crosslinking Euthanize 2 adult mice using carbon dioxide (CO2) for 1-2 min or until breathing stops. Next, perform cervical dislocation on each mouse. Harvest about 100 mg of testes from mice of appropriate age (one adult testis in this study) for each immun…
