A novel application of CIM monolithic supports for concentrating Potato spindle tuber viroid from water samples

Potato spindle tuber viroid (PSTVd) is the causal agent of a number of agriculturally important diseases. It is a single-stranded, circular and uncapsidated RNA molecule with 359 nucleotides and no coding capacity. Because of its complex secondary/tertiary structure it is very stable ex vivo and it is easily transmitted mechanically by contaminated hands, tools, machinery, etc. In this work, we describe the development and optimization of a method for concentrating PSTVd using CIM monolithic supports.
