Abstract |
For structural, biochemical or pharmacological studies, it is required to have pure RNA in large quantities. We previously devised a generic approach that allows efficient in vivo expression of recombinant RNA in Escherichia coli. We have extended the "tRNA scaffold" method to RNA/protein co-expression in order to express and purify RNA by affinity in native condition. As a proof-of-concept, we present the expression and the purification of the AtRNA-mala in complex with the MS2 coat protein. |
