dc.description.abstractRNA-based biopharmaceuticals are being envisioned as a powerful tool for the development of innovative medicines for prevalent diseases. Despite their undeniable relevance, the ubiquitous unstable nature of RNA coupled with the laborious and costly methods required for its extraction and purification still challenge the widespread application of this biopolymer. On the basis of the high affinity between amino-acids and RNA and the favorable nucleic acids-stabilization properties exhibited by amino-acid-based ILs (AA-ILs), a set of ILs is herein studied both as preservation media and components of aqueous biphasic systems (ABS). The global aim of this work is to develop alternative cost-effective and sustainable purification-preservation platforms for RNA with the ultimate goal of purifying RNA from a complex recombinant lysate, taking advantage of the “designer solvent” character of ILs. AA-ILs comprising cholinium, L-arginine, L-lysine and L-histidine as cations and combined with chloride, DL-aspartate, L-tyrosine or L-phenylalanine were synthesized, characterized, and their ability to form two phases with distinct salts and polymers investigated. All the AA-ILs in study were able to form ABS with polypropylene glycol with a molecular weight of 400 g.mol-1 (PPG 400), being subsequently investigated as extraction and preservation platforms for RNA. It was demonstrated that RNA was successfully extracted to the IL-rich phase while ensuring that its integrity and stability are preserved. Ongoing work is focusing the application of the most promising AA-IL-based ABS for the separation of RNA and genomic DNA from complex recombinant lysates.pt_PT
