Abstract: A nucleic acid molecule can be annealed to an appropriate immobilized primer. The primer can then be extended and the molecule and the primer can be separated from one another. The extended primer can then be annealed to another immobilized primer and the other primer can be extended. Both extended primers can then be separated from one another and can be used to provide further extended primers. The process can be repeated to provide amplified, immobilized nucleic acid molecules. These can be used for many different purposes, including sequencing, screening, diagnosis, in situ nucleic acid synthesis, monitoring gene expression, nucleic acid fingerprinting, etc.

Abstract: The invention provides methods for determining genome-wide sequence variations associated with a phenotype of a species in a hypothesis-free manner. In the methods of the invention, a set of restriction fragments for each of a sub-population of individuals having the phenotype are generated by digesting nucleic acids from the individual using one or more different restriction enzymes. A set of restriction sequence tags for the individual is then determined from the set of restriction fragments. The restriction sequence tags for the sub-population of organisms are compared and grouped into one or more groups, each of which comprising restriction sequence tags that comprise homologous sequences. The obtained one or more groups of restriction sequence tags identify the sequence variations associated with the phenotype. The methods of the invention can be used for, e.g., analysis of large numbers of sequence variants in many patient samples to identify subtle genetic risk factors.

Abstract: An electrophoretic method for purifying a nucleic acid sample is disclosed. According to the method, the electrophoresis is effective to substantially reduce the concentration of contaminants relative to the concentration of desired nucleic acid in the nucleic acid sample, thereby producing a purified nucleic acid. In the method, the loading and recovery wells may be the same or different, and the electric fields may be DC or alternating.

Abstract: The microfluidic dispensing device includes a patterned seal having a specified arrangement of holes and groves, and an connection plate having passages corresponding to the holes in the patterned seal. The patterned seal and the connection plate are configured to stack onto a planar substrate, such as a glass slide, and are sealed together and against the substrate by a negative pressure, or vacuum, applied through the connection plate. When the patterned seal is secured against the substrate, the grooves in the patterned seal form a network of channels for delivering fluids to specified regions on the substrate. The connection plate preferably includes one or more connectors for attaching fluid and/or vacuum lines, and optionally includes one or more sensors to monitor operation of the device. The system of the present invention also includes a device for automatically assembling and handling the microfluidic dispensing device.

Abstract: The invention concerns a method for separating particles or molecules whereby these particles or molecules are introduced in a separating medium and a moving force is applied to them in said medium. The method is characterised in that the separating medium is a ferrofluid, i.e. a colloidal suspension of magnetic particles and a magnetic field is applied to this ferrofluid generating therein at least an alternation of a zone rich in magnetic particles and a zone poor in magnetic particles, part at least of the region of the ferrofluid in which this alternation is generated is passed through by the particles or molecules to be separated during their migration.

Abstract: Different nucleic acid molecules present at different locations can be sequenced in parallel Primers that are annealed to the nucleic acid molecules can be provided. Each location can then be provided with a nucleic acid polymerase and a nucleotide. It can then be determined whether or not the nucleotide has been used in primer extension and the process can be repeated. As an alternative to using primers, a nick in a double stranded nucleic acid molecule can provide a 3′-OH group for chain extension.
