Said preparation is suitable as a drug particularly in gene therapy.
Abstract: A method is described for the direct, exponential amplification and sequencing (“DEXAS”) of a DNA molecule from a complex mixture of nucleic acids, wherein truncated DNA molecules as well as DNA molecules of full length are synthesized simultaneously and exponentially between two positions on the said DNA molecule, which initially contains a DNA molecule in a thermocycling reaction, a first primer, a second primer, a reaction buffer, a thermostable DNA polymerase, a thermostable pyrophosphatase (optionally), deoxynucleotides or derivatives thereof and a dideoxynucleotide or derivatives thereof.
Abstract: A pharmaceutical composition is disclosed, as well as its use in tumour diagnosis, therapy and prevention, methods for diagnosing, treating and preventing tumours, and antibodies and their use.
Abstract: A purified DNA polymerase exhibiting reverse transcriptase activity in the presence of magnesium ions and/or manganese ions having reduced or no 5′-3′-exonuclease activity and substantially no RNaseH activity and obtainable from Carboxydothermus hydrogenoformans.
Abstract: The discriminating capability of hybridization assays is increased by a combination of labelled primers which produce amplificates of one strand of a nucleic acid with a capture probe which is complementary to the same strand of the nucleic acid.
Abstract: The method of polypeptide synthesis in eukaryotic or porkaryotic cell-free systems based on a modified verion of synthesis in the continuous flow or continuous exchange modes when, in addition to input into the reaction mixture of components maintaining the synthesis and removal from the reaction mixture of low molecular weight components inhibiting the synthesis, the concentration of at least one of the components selected from the group consisting of Mg2+, K+, NTP, polyamines or their combinations determining the productivity of the synthesis is continuously changed within the given range of concentrations, while the concentrations of the other components are maintained constant.
