摘要： The invention relates to a non-invasive, simple, inexpensive, quick method to assess embryo competence in vitro by detecting nucleic acid-containing extracellular vesicles in the culture medium of the embryo. The culture medium may be fixed before being stained with propidium iodide and analysed by flow cytometry.

摘要： Gold nanorattle probes are provided that are highly tunable, physiologically stable, and ultra-bright Raman probes for in vitro and in vivo surface-enhanced Raman scattering (SERS) applications. The nanorattles contain an essentially uniform gap between core and shell that is tunable and can range from 2nm to 10nm in width. This provides numerous advantages including allowing for increased loading with a variety of dye molecules that exhibit SERS in various spectral regions, including the “tissue optical window” for in vivo studies. In addition, the nanorattle probes provide an internal label when used in diagnostic methods to detect nucleic acids, proteins and other biotargets. The nanorattles have an essentially spherical gold metal nanoparticle core, a porous material of silver metal of an essentially uniform width surrounding the nanoparticle core that is loaded with one or more SERS reporter molecules, and an outer gold metal shell encapsulating the porous material.

摘要： A method of determining the sequence of a target nucleic acid is provided. The method can include the steps of (a) performing a defined number of incremental extension cycles to produce a population of nucleic acid fragments having different portions of the target nucleic acid wherein the individual nucleic acid fragments in the population have a defined length that is correlated with the number of incremental extension cycles; (b) determining the sequence of the first end of individual nucleic acid fragments in the population, thereby providing first end sequences; (c) determining the sequence of the second end of individual nucleic acid fragments in the population, thereby providing second end sequences; and (d) determining the sequence of the target nucleic acid based on the first end sequences, the second end sequences and the defined length.
