摘要： A device positioning an object according to a given direction, including a frame, a holderfor holding the object, the holder being movable relative to the frame according to the given directio, a main lever extending between a first point and a second point, said main lever being rotatably mounted to the frame via a first pivot link connecting the main lever and the frame at the first point of the main lever, the main lever being connected to the holder at a third point which is arranged between the first point and the second point, so that a displacement of the second point of the main lever relative to the frame according to the given direction causes displacement of the holder in said given direction.

摘要： The present invention relates to a method of preparation of substrates for nucleic acid sequencing reactions. More specifically, the present invention provides a new method of preparing hairpins using force-induced strand invasion. Hairpins prepared by this method and methods of nucleic acid analysis using these hairpins are also part of the present invention.

摘要： The present invention relates to a method for determining whether a protein binds to a specific DNA sequence. This method is useful in particular for identifying modifications to the DNA sequence (e.g. methylations) via the binding of proteins that specifically recognize those modifications (e.g. antibodies), but also to identify the binding sequence on DNA of a variety of proteins.

摘要： The present invention relates to a system of nanopore sequencing using nucleic-acid binding proteins wherein the activity of the said protein and the passage of the sequenced nucleic acid molecule through the nanopore are coordinated. In particular, the present invention enables an easy synchronization of nanopore capture with polynucleotide unwinding, which in turn affords an easy way to repeat the whole process of capture and nucleotide characterization.

摘要： A method for detecting a reversibly photoswitchable chemical species in a sample, includes the steps of: a) illuminating the sample with light suitable to be absorbed by the chemical species triggering a reaction affecting an optical property of the chemical species, the first light being periodically-modulated at a fundamental modulation frequency; b) measuring the evolution of the optical property; c) extracting at least one of an in-phase component at a frequency which is an even multiple of the fundamental modulation frequency; and a quadrature component at a frequency which is an odd multiple of the fundamental modulation frequency of a signal representing the evolution; and d) using the extracted component or components for detecting the chemical species. An apparatus for carrying out the method is also provided.
