  • Patent number: 10041115
    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.

  • Publication number: 20170052175
    Abstract: Provided herein are methods of using photocleavable labels for multiplex and serial antigen detection. The methods comprise detecting the presence of photocleavable labels, which are conjugated through functional linkers to antigen-binding complexes, which in turn non-covalently bind to antigens. The presence of a photocleavable label is indicative of the presence of an antigen specifically or selectively bound by an antigen-binding complex. Also provided are apparatuses for using photocleavable labels for multiplex and serial antigen detection.

  • Patent number: 8969535
    Abstract: Provided are novel nucleotides, nucleoside, and their derivatives described herein, that can be used in DNA sequencing technology and other types of DNA analysis. In one embodiment, the nucleotide or nucleoside with an unprotected 3?-OH group is derivatized at the nucleobase to include a fluorescent dye attached via a linker to a photocleavable terminating group. The photocleavable-fluorescent group is designed to terminate DNA synthesis as well as be cleaved so that DNA oligomers can be sequenced efficiently in a parallel format. The design of such rapidly cleavable fluorescent groups on nucleotides and nucleosides can enhance the speed and accuracy of sequencing of large oligomers of DNA in parallel, to allow rapid whole genome sequencing, and the identification of polymorphisms and other valuable genetic information, as well as allowing further manipulation and analysis of nucleic acid molecules in their native state following cleavage of the fluorescent group.
