International Classification:

C12Q 1/68
C07H 19/10
C07H 19/14

US Classification:

435 61, 536 2626

Abstract:

The present invention relates generally to 3′-OH unblocked nucleotides and nucleosides labeled and unlabeled with 5-methoxy-substituted nitrobenzyl-based photocleavable terminating groups for use in methods and systems related to DNA and RNA sequencing and analysis. These compounds may be used as reversible terminators as they exhibit fast nucleotide incorporation kinetics, single-base termination, high nucleotide selectivity, and rapid terminating group cleavage that results in a naturally occurring nucleotide.

Abstract:

The present invention relates to a positron tomography imaging apparatus for a multiphase flow in an oil pipeline, which apparatus utilizes positron and electron annihilation generating a pair of coincidence gamma-rays of 511 keV energy as tomography imaging means and provides an on-line tomography imaging function for metering a multiphase flow in an oil pipeline of an oil field. The apparatus comprises a plurality of sets of parallel high-precision gamma-ray detector arrays with a particular space structure arrangement, a positron radioactive source and a shield, and can acquire a phase fraction of such multiphase flow mixture as oil, gas and water under a condition of a single radioactive source by combining an image processing function. The design of a plurality of sets of high-precision detector arrays also greatly improves accuracy of a multiphase flow metering and its applicability in multiphase flows of different flow patterns. The video information of fluid generated by it will significantly enrich oil, gas metering information for petroleum industry and provide basic data for a more effective reservoir management and production optimization.
