Abstract: Method for transmitting a data stream between a mobile data carrier and a playback device, in which authentication data for setting up a second transmission channel from the data carrier to the playback device is transmitted via a first transmission channel set up between the data carrier and the playback device by an electromagnetic field emitted by the playback device. Following verification of authentication data, the second transmission channel is set up, via which the data stream is transmitted from the data carrier to the playback device by a radio signal from a transmitting antenna of the data carrier. The power supply to the transmitting antenna is provided via the first transmission channel, and the second transmission channel is maintained only as long as the first transmission channel is maintained.

Abstract: This invention relates to the field of nucleic acid chemistry, more specifically to the field of compositions of matter that comprise triphosphates of modified 2?-deoxynucleosides and oligonucleotides that are formed when these are appended to the 3?-end of a primer, wherein said modifications comprise NH2 moiety attached to their 3?-hydroxyl group and a fluorescent species in a form of a tag affixed to the nucleobase via a linker that can be cleaved. Such compositions and their associated processes enable and improve the sequencing of oligonucleotides using a strategy of cyclic reversible termination, as outlined in U.S. Pat. No. 6,664,079. Most specifically, the invention concerns compositions of matter that are 5?-triphosphates of ribo- and 2?-deoxyribonucleosides carrying detectable tags and oligonucleotides that might be derived from them.

Abstract: Processes are disclosed that use 3?-reversibly terminated nucleoside triphosphates to analyze DNA for purposes other than sequencing using cyclic reversible termination. These processes are based on the unexpected ability of terminal transferase to accept these triphosphates as substrates, the unexpected ability of polymerases to add reversibly and irreversibly terminated triphosphates in competition with each other, the development of cleavage conditions to remove the terminating group rapidly, in high yield, and without substantial damage to the terminated oligonucleotide product, and the ability of reversibly terminated primer extension products to capture groups. The presently preferred embodiments of the disclosed processes use a triphosphate having its 3?-OH group blocked as a 3?-ONH2 group, which can be removed in buffered NaNO2 and use variants of Taq DNA polymerase, including one that has a replacement (L616A).

Abstract: Specific sequences of DNA are often detected by a process that comprises a step where the sequence to be detected (the “analyte”) binds to give a duplex with a DNA molecule or analog that is complementary in the Watson-Crick sense to some portion of the analyte in an aqueous “assay environment” that may contain buffer, salt, and/or detergent. Such purely aqueous systems cannot be exposed indefinitely to the environment, however, as the water in the system will evaporate. Further, such systems often support the growth of bacteria and other organisms, destroying their effectiveness. This invention provides for compositions of matter and processes that use them that comprise assay mixtures containing more than 40% formamide. This mixture remains a liquid at equilibrium with water in environments normally inhabited by humans. This invention also provides for mixtures containing formamides that include detergents.
