In diesem Video beschreiben wir die systematische Evolution von Liganden mit der Exponentialanreicherungsmethode (SELEX), um spezifische RNA-Bindungssequenzen für ein Zielprotein von Interesse zu identifizieren. Das Protein wird mit einem großen Pool randomisierter RNA-Sequenzen inkubiert, und die proteinbindenden RNA-Sequenzen werden isoliert, PCR-amplifiziert und sequenziert, um ihre Proteinbindungsstellen zu identifizieren.
