The present invention relates to a method for isolating and purifying nucleic acids, preferably comprising genomic DNA, from biological samples comprising the steps of lysing the sample using a lysis buffer comprising a source of anionic surfactant ions, optionally disintegrating the RNA present in the lysate, precipitating the surfactant ions from the lysate, and separating the nucleic acids from the precipitate and further contaminants by size-exclusion chromatography. The invention furthermore relates to a lysis buffer, a method of lysing cells and a kit for the isolation and purification of nucleic acids.
摘要:
In an exhaust gas turbocharger for an internal combustion engine of a motor vehicle with a turbine comprising a turbine housing with at least a first and a second spiral channel, each being coupled to an exhaust gas line of an exhaust gas tract of the internal combustion engine for conducting exhaust gas to a turbine wheel arranged within the turbine housing and driving a compressor wheel of a compressor of the exhaust gas turbocharger, an area ratio Qg of the turbine corresponds to the formula Qg=(Aλ+AAGR)/AR>0.40, wherein Aλ refers to a narrowest flow cross-section of the first spiral channel, AAGR to a narrowest flow cross-section of the second spiral channel (52b) and AR to a wheel exit flow cross-section of the turbine exhaust channel. The invention further relates to a motor vehicle with an internal combustion engine and such an exhaust gas turbocharger.

摘要:
A device for cutting textile and non-textile sheet materials with a sewing machine having a turning device (9) that can be mounted on the lower end of the needle bar (5). A cutting needle (23) is inserted from below into the turning device (9) instead of a sewing needle and can be brought into the desired cutting position, for example, by a fin (17) that projects from the turning device (9).
摘要:
In the turbine housing for an exhaust gas turbocharger of a drive assembly at least one spiral channel, which can be coupled to an exhaust gas line of the drive assembly is provided A receiving chamber for a turbine wheel to which exhaust gas can be supplied is disposed upstream of the at least one spiral channel. The turbine wheel is disposed in the turbine housing so as to be rotatable about a rotational axis. A guide baffle is arranged fixed to the turbine housing in a transition region between the at least one spiral channel, the guide baffle being connected to the turbine housing by a metal-to-metal joint whereby the guide baffle is connected to the turbine housing in a particular tight manner.
