| 20110117628 | METHOD FOR CONCENTRATING AND ISOLATING BIOMOLECULES OR VIRUSES - A simple and convenient method for concentrating a biomolecule, including protein or nucleic acid molecules, from a sample. Purified and isolated biomolecules obtained by this method. Methods for improving the specificity or sensitivity of detecting a biomolecule by concentration and/or purification or isolation of the biomolecule according to the method of the invention. | 05-19-2011 |
| 20110091879 | MOBILE DEVICE FOR ISOLATION OF NUCLEIC ACIDS - The invention relates to a mobile device system, comprising a hand-held device and a test kit for the mobile isolation of nucleic acids. The hand-held device comprises at least one sample block for inserting sample containers, a sample block holder with boreholes or recesses for accommodating the sample blocks, a device base with electronic control units for the sample blocks, a voltage source and a connection to the sample block holder, as well as a test kit for the isolation of nucleic acids. The hand-held device is characterized in that the sample blocks can be removed from the sample block holder and the sample block holder can be removed from the device base. | 04-21-2011 |
| 20110039261 | MOBILE RAPID TEST SYSTEM FOR NUCLEIC ACID ANALYSIS - A mobile rapid test system for nucleic acid analysis. A method comprising the steps of amplification of the nucleic acids by means of rapid-PCR technology, conversion of a double-stranded amplification product into a single-stranded DNA fragment, hybridization with a labeled probe and detection of the nucleic acids on a lateral-flow test strip. A device comprising a reaction cavity which preferably consists of a thin film, inlet and outlet openings for the reaction cavity, one or more heatable sample blocks which are connected to miniaturized cooling bodies and a window for reading off the result. The lateral-flow test strip is a component of the mobile rapid test system. Operation of the instrument system requires no external power source, but only batteries or a rechargeable battery. | 02-17-2011 |
| 20100222562 | METHOD AND TEST KIT FOR THE SEPARATION, PURIFICATION AND RECYCLING OF LONG- AND SHORT-CHAIN NUCLEIC ACIDS - Long- and/or short-chain nucleic acids are separated, purified and recovered by binding the nucleic acid to a solid phase using a binding buffer, to obtain a bonded nucleic acid, and eluting of the bonded nucleic acid from the solid phase, wherein the binding buffer comprises at least one citric acid salt and at least one alcohol. | 09-02-2010 |
| 20100221718 | METHOD AND RAPID TEST FOR DETECTION OF SPECIFIC NUCLEIC ACID SEQUENCES - A universally usable method for specific detection of target nucleic acid sequences, which method can be performed very rapidly and also simply and furthermore which does not need any expensive instrumental systems. The method is intended to be suitable as a molecular genetic rapid test and to respect the requirements of diagnostic specificity assurance. In this regard it is important that only one specific amplification product be detected and that amplification artifacts can be unambiguously discriminated. A nucleic acid amplification kit suitable for performing this method. | 09-02-2010 |
| 20100099099 | METHOD AND TEST KIT FOR THE RAPID DETECTION OF SPECIFIC NUCLEIC ACID SEQUENCES, ESPECIALLY FOR DETECTING OF MUTATIONS OR SNPs - A method and a test kit for rapid detection of specific nucleic acid sequences, especially for detection of mutations or single nucleotide polymorphisms (SNPs), in which the detection reaction takes place in two steps. The first step involves the target-specific amplification reaction, coupled with the probe-hybridization reaction using fluorescence-labeled allele-specific amplification primers. In the second step, the fluorescence is detected by means of commercial fluorescence readers. Genotyping is carried out from the ratio of the end-point fluorescence of the samples and negative controls. | 04-22-2010 |
| 20090253903 | METHOD FOR PARALLEL ISOLATION OF VIRAL NUCLEIC ACIDS - Parallel isolation of a double-stranded nucleic acid and a single-stranded nucleic acid is possible from a sample that contains these acids, without separating the acids, by mixing the sample with a lysis buffer having high salt concentration or low salt concentration, or having a proteolytic enzyme. The sample that contains nucleic acid before its lysis, or the sample that has already been lysed or homogenized, is adjusted with a binding buffer in such a manner that the total nucleic acid is adsorbed onto a solid carrier. The binding buffer contains at least one non-ionic detergent in a high concentration. With the exception of the detergent, the sample contains no other non-acidic organic component miscible in water. The carrier with the adsorbed total nucleic acid is removed. The adsorbed total nucleic acid is washed and eluted. | 10-08-2009 |
| 20090069555 | DEVICE AND PROCEDURE FOR AUTOMATED ISOLATION AND PURIFICATION OF NUCLEIC ACIDS FROM COMPLEX STARTING MATERIALS OF THE USERS CHOICE - A reaction unit containing a bottom part and a top part for pipetting a liquid, wherein the bottom part contains a reaction cavity with a permeable filter grid insert and the top part contains a reaction cavity which can be fixed on said bottom part and contains a cavity or covering for receiving a magnet. | 03-12-2009 |
| 20090068662 | METHOD AND TEST KIT FOR THE SEPARATION, PURIFICATION AND RECYCLING OF LONG- AND SHORT-CHAIN NUCLEIC ACIDS - Long- and/or short-chain nucleic acids are separated, purified and recovered by binding the nucleic acid to a solid phase using a binding buffer, to obtain a bonded nucleic acid, and eluting of the bonded nucleic acid from the solid phase, wherein the binding buffer comprises at least one citric acid salt and at least one alcohol. | 03-12-2009 |
