摘要： The invention generally provides a sieve valve including: a substrate defining a channel; a flexible membrane adapted and configured for deployment at an intersection with the channel; and one or more protrusions extending into the channel from the substrate or the flexible membrane. The one or more protrusions define a plurality of recesses extending beyond the intersection between the channel and the flexible membrane;A microfluidic circuit including one or more sieve valves. In particular embodiments, the circuit comprises one or more input/output valves. The one or one or more input/output valves can include one or more input valves and one or more output valves.The microfluidic circuit can further include a mixing circuit. At least one of the sieve valves can be positioned between the one or more input/output valves and the mixing circuit.The invention further provides methods of using the device for the analysis of samples comprising cells.

摘要： A method for separating a nucleic acid from a specimen includes accommodating a specimen in an accommodation space provided in a nucleic acid-collecting member, transferring a treatment reagent to the nucleic acid-collecting member by connecting a treatment reagent-accommodating container to a treatment reagent-supplying opening of the nucleic acid-collecting member, obtaining a mixture by mixing the specimen and the treatment reagent in a mixing space formed by combining an inner container space of the treatment reagent-accommodating container and the accommodation space of the nucleic acid-collecting member, and pressure-feeding the mixture by reducing a volume of the inner container space of the treatment reagent-accommodating container and discharging the mixture from an mixture-discharging opening of the nucleic acid-collecting member via a carrier that adsorbs the nucleic acid released in the mixture while allowing the mixture to permeate therethrough.

摘要： Device and method for automated extraction of nucleic acids, comprising a body that can be immersed partly or completely in a reaction cavity, characterized in that at least the part immersed in the reaction cavity has a non-smooth surface. After lysis, an organic substance, preferably alcohols or ketones, is mixed with a biological sample. This mixture is now brought into contact with a material characterized by a non-smooth surface. Under these conditions, nucleic acids are adsorbed on the surface of the material being used. Thereupon washing steps with known alcoholic washing solutions may be carried out. After drying, the adsorbed nucleic acid is detached from the material by addition of water or a buffer of low salt concentration, whereupon it can be used for downstream applications.
