Applied Biosystems is one of the various brands under the Life Technologies brand of Thermo Fisher Scientific corporation. The brand is focused on integrated systems for genetic analysis, which include computerized machines and the consumables used within them .In 2008, a merger between Applied Biosystems and Invitrogen was finalized, creating Life Technologies. The latter was acquired by Thermo Fisher Scientific in 2014. Prior to 2008, the Applied Biosystems brand was owned by various entities in a corporate group parented by PerkinElmer. The roots of Applied Biosystems trace back to GeneCo , a pioneer biotechnology company founded in 1981 in Foster City, California. Through the 1980s and early 1990s, Applied Biosystems, Inc operated independently and manufactured biochemicals and automated genetic engineering and diagnostic research instruments, including the principal brand of DNA sequencing machine used by the Human Genome Project consortium centers. Applied Biosystems' close ties to the consortium project led to the idea for the founding of Celera Genomics in 1998 as one of several independent competitors to the consortium.In 1993 Applied Biosystems, Inc was delisted from the NASDAQ when it was acquired by the old company known then as Perkin-Elmer . As the PE Applied Biosystems Division under that parent in 1998, it became consolidated with other acquisitions as the primary PE Biosystems Division. In 1999 its parent company reorganized and changed its name to PE Corporation, and the PE Biosystems Group again became publicly traded, as a tracking stock of its parent, along with its sister tracking stock company, Celera Genomics. In 2000 the parent became Applera Corporation. The Applied Biosystems name also returned that year, in the name change of the tracking stock from PE Biosystems Group to Applera Corporation-Applied Biosystems Group , an S&P 500 company, which remains as a publicly traded operating group within Applera Corp., along with its sibling operating group, Applera Corporation-Celera Group. Applera derives its name from the combination of its two component groups' names, Applera In November 2008, a merger between Applied Biosystems and Invitrogen was finalized "creating a global leader in biotechnology reagents and systems". The new company is called Life Technologies. Wikipedia.

The present disclosure relates to methods of identifying target nucleic acids by using coded molecules and its analysis by translocation through a nanopore. Generally, coded molecules are subject to a target polynucleotide dependent modification. The modified coded molecule is detected by isolating the modified coded molecules from the unmodified coded molecules prior to analysis through the nanopore or by detecting a change in the signal pattern of the coded molecule when analyzed through the nanopore.

The present invention relates to mutant DNA polymerases that exhibit reduced discrimination against labeled nucleotides into polynucleotides. The DNA polymerases of the invention have at least one mutation in the nucleotide label interaction region of the enzyme such the mutation results in reduced discrimination against labeled nucleotides. The nucleotide label interaction regions is located at portions of the O-helix, (ii) the K helix, and (iii) the inter O-P helical loop of Taq DNA polymerase or analogous positions in other DNA polymerases. In addition to providing novel mutant DNA polymerases, the invention also provides polynucleotides encoding the subject mutant DNA polymerases. The polynucleotides provided may comprise expression vectors for the recombinant production of the mutant polymerases. The invention also provides host cells containing the subject polynucleotides. The invention also includes numerous methods of using the subject DNA polymerases, including uses for chain termination sequencing and PCR. Another aspect of the invention is to provide kits for synthesizing fluorescently labeled polynucleotides in accordance with the methods of the invention. Kits of the invention comprise a mutant DNA polymerase of the invention and a fluorescently labeled nucleotide that exhibits reduced discrimination with respect to the mutant DNA polymerase in the kit.

An apparatus and method are provided for differentiating multiple detectable signals by excitation wavelength. The apparatus can include a light source that can emit respective excitation light wavelengths or wavelength ranges towards a sample in a sample retaining region, for example, in a well. The sample can contain two or more detectable markers, for example, fluorescent dyes, each of which can be capable of generating increased detectable emissions when excited in the presence of a target component. The detectable markers can have excitation wavelength ranges and/or emission wavelength ranges that overlap with the ranges of the other detectable markers. A detector can be arranged for detecting an emission wavelength or wavelength range emitted from a first marker within the overlapping wavelength range of at least one of the other markers.
