AGO2 proteininin saflaştırılması ve mikro RNA etkileşimlerinin incelenmesi

AGO2 proteininin saflaştırılması ve mikro RNA etkileşimlerinin incelenmesi

Abstract

Bu çalışmada; RNA interferansı efektör proteini olarak bilinen Argonat 2 (AGO2) proteininin immunoafinite saflaştırılması ve AGO2 proteini içeren nanoprotein partiküller hazırlanarak, hazırlanan bu nanoprotein partiküllerin mikro RNA (miRNA) bağlanma etkinliklerinin kantitatif olarak belirlenmesi amaçlanmıştır. Bunun için ilk aşamada, fotosensitif rutenyum tabanlı amino asit monomeri, bis(2-2'-bipiridil)(MATrp)2-rutenyum (II) kullanılarak ANADOLUCA metoduna göre poli(HEMA-ko-anti-AGO2) kriyojeli sentezlenmiş ve SEM, FT-IR ve su tutma kapasitesi testi ile karakterize edilmiştir. Daha sonra; sentezlenen bu kriyojel kolon ile AGO2 proteini, sığır karaciğeri sitoplazma ekstraktından tek adımda immunoafinite yoluyla saflaştırılmıştır. Saflaştırılan örneğin moleküler ağırlığı ve saflığının belirlenmesi için SDS-PAGE metodu; örnek içerisindeki AGO2 proteininin varlığını net olarak belirlemek için ise EMSA metodu kullanılmıştır. En son aşamada; AGO2 bazlı nano blok polimerler fotosensitif mikroemülsiyon polimerizasyonu metodu kullanılarak hazırlanmış ve hazırlanan bu partiküller SEM ve zeta ile karakterize edilip ticari miR-335’ e bağlanma afiniteleri belirlenmiştir. Sonuç olarak, miR-335’ in AGO2 partiküllerine yüksek bir afinite ile bağlandığı belirlenmiştir.
