Abstract
The use of mitochondria-based systematic evolution of ligands by exponential enrichment (SELEX) was explored. Mitochondria were isolated from rat liver and confirmed intact by respiratory control index. Isolated mitochondria and a 2'-F RNA random library were mixed and the bound RNAs collected. The counter selection was applied with nucleus and unbound RNAs were collected. After 7 rounds of selection, two sequences (Mitomer1 and Mitomer2) were verified to bind to mitochondria and the truncated Mitomer2 (short Mitomer2) showed better binding to isolated mitochondria than Mitomer1.
