    摘要: Fluorescent conjugates are employed providing combinations of a fluorescent sensitizer and a fluorescent phycobiliprotein. The conjugates find use in applications where large Stokes shifts, high absorption coefficients and high fluorescence quantum yields are desired. Particularly, combinations of phycobiliproteins are employed where the wavelength of excitation may be 50 nm or more different from the emission wavelength.

    摘要: The invention provides multifunctional fusion constructs which are rapidly incorporated into a macromolecular structure such as a phycobilisome such that the fusion proteins are separated from one another and unable to self-associate. The invention provides methods and compositions for displaying a functional polypeptide domain on an oligomeric phycobiliprotein, including fusion proteins comprising a functional displayed domain and a functional phycobiliprotein domain incorporated in a functional oligomeric phycobiliprotein. The fusion proteins provide novel specific labeling reagents.

    摘要: The present invention provides methods and kits for identifying nucleotides at a variant site in a target molecule by forming fluorescence resonance energy transfer labeled product. The location and type of fluorescent labels in the labeled product provide strong signals and relatively high spectral purity that facilitate detection. Utilizing various secondary labels and different combinations of acceptor and donor labels, certain methods permit multiple analyses to be conducted simultaneously and at high throughput. The methods can be used in a variety of applications such as analyzing point mutations and single nucleotide polymorphisms (SNPs). In addition, the methods have utility in other applications in which specific sequence information is of value, including detection of pathogens, paternity disputes, prenatal testing and forensic analysis.

    摘要: The invention provides a method for diagnosis of genetic abnormalities or other genetic conditions which can be readily automated. The method is used to determine the presence or absence of a target sequence in a sample of denatured nucleic acid and entails hybridizing the sample with a probe complementary to a diagnostic portion of the target sequence (the diagnostic probe), and with a probe complementary to a nucleotide sequence contiguous with the diagnostic portion (the contiguous probe), under conditions wherein the diagnostic probe remains bound substantially only to the sample nucleic acid containing the target sequence. The diagnostic probe and contiguous probe are then covalently attached to yield a target probe which is complementary to the target sequence, and the probes which are not attached are removed. In the preferred mode, one of the probes is labeled so that the presence or absence of the target sequence can then be tested by melting the sample nucleic acid-target probe duplex, eluting the dissociated target probe, and testing for the label. In another embodiment, the testing is accomplished without first removing probes not covalently attached, by attaching a hook to the probe that is not labeled, so that the labeled target probe may be recovered by catching the hook. In both instances, the presence of both the diagnostic probe and the contiguous probe is required for the label to appear in the assay. The above method is then applied to the detection of genetic diseases.

    摘要: Novel fluorescent heterodimeric DNA-staining energy transfer dyes are provided combining asymmetric cyanine azole-indolenine dyes, which provide for strong DNA affinity, large Stokes shifts and emission in the red region of the spectrum. The dyes find particular application in gel electrophoresis and for labels which may be bound to a variety of compositions in a variety of contexts. Kits and individual compounds are provided, where the kits find use for simultaneous detection of a variety of moieties, particularly using a single narrow wavelength irradiation source. The individual compounds are characterized by high donor quenching and high affinity to dsDNA as a result of optimizing the length of the linking group separating the two chromophores.
