Abstract: Fluorescent labeled reporter compounds having a modified cyanine dye that is coupled to a nucleotide derivative through a linker are disclosed. The compounds are useful for nucleic acid sequence analysis. The fluorescent labeled reporter compounds are ring-locked cyanine dyes that are coupled to a nucleotide derivative, such as a modified DNA base, through a linker. These fluorescent labeled reporter compounds can be used as DNA chain-terminators in DNA synthesis to generate DNA fragments that are fluorescently-labeled at the 3?-terminal end of the DNA fragment.

Abstract: An analyte detection system utilizing a combination of fluorescent labels for labeling particles and an analyte specific fluorescent analyte detection dye. The particles contain a combination of fluorescent labels for coding the particles and an analyte specific fluorescent dye. The particles can be used to identify and quantify analytes in an analytical sample by reaction of the analytical sample with the particles. An analytical device can identify the particles according to the combination of fluorescent labels. The device can then correlate the identified particle with the analyte specific fluorescent analyte detection dye. Multiple subpopulations of particles can be used to identify and quantify multi-analytes in a single analytical sample. Near infrared (NIR) fluorescent labels useful in the detection system are also provided.

Abstract: A method for making a preconjugate which includes immunogenic species of a polymorphic analyte. The method is carried out by reacting an activated binding moiety, and a polymorphic analyte at room temperature for between about 10 hours and about 60 hours. The attaching reaction results in an excess of the preconjugate which includes the immunogenic species of the polymorphic analyte. The preconjugate can be used to make an immunoreactive conjugate useful as a developer antigen in a competitive inhibition immunoassay for the polymorphic analyte.
