Abstract: The present invention relates to the field of nucleic acid purification. In particular, it relates to methods and tools for purifying nucleic acids in a sample; which are compatible with high-throughput sequencing and diagnosis. The inventors have shown that nucleic acid binding proteins recruited to polymerized tubulin (i.e. microtubules) could, subsequently, be isolated from cell lysates. Surprisingly, it has now been found that the amount of recovered nucleic acid found in these microtubule pellets increases dramatically in the presence of nucleic acid-trapping proteins comprising a nucleic acid-binding moiety and a polymerized tubulin-binding moiety, by comparison to proteins devoid of the nucleic acid-binding moiety; and that the recovery of the purified nucleic acids was itself particularly efficient. This purification method is particularly amenable to high-throughput sequencing and/or in the context of a diagnosis method for identifying or comparing the amount of nucleic acids in a set of samples.

Abstract: A method for detecting an interaction between one or more protein bait and one or more candidate prey in a eukaryotic cell, comprising the steps of: a) providing an eukaryotic cell expressing (i) one or more protein bait, and (ii) one or more candidate prey, wherein said protein bait comprises a bait moiety and a polymerized-tubulin binding moiety. b) determining the occurence of an interaction between said one or more protein bait and said one or more candidate prey in the eukaryotic cell, wherein said protein bait is bound to polymerized tubulin in the eukaryotic cell, thereby localizing said one or more candidate prey along said polymerized tubulin, thereby detecting said interaction.
