Summary

Automatically generated

Complessi RNA/proteici purificati mediante botin-streptavidina strategia sono eluiti per soluzione in condizioni denaturanti in forma inadatta per ulteriore purificazione e analisi funzionale. Qui, descriviamo una modifica di questa strategia che utilizza un linker foto-spaccabili in RNA e un delicato passaggio di UV-eluizione, producendo complessi RNA/proteine native e completamente funzionale.
