    InPlex™ CF Molecular Test is an in vitro diagnostic device used to simultaneously detect and identify a panel of mutations and variants in the cystic fibrosis transmembrane conductance regulator (CFTR) gene in genomic DNA samples isolated from human peripheral whole blood specimens. The panel includes mutations and variants recommended by the 2004 American College of Medical Genetics (ACMG). The InPlex™ CF Molecular Test is a qualitative genotyping test that provides information intended to be used for cystic fibrosis carrier screening as recommended by ACMG and the 2005 American College of Obstetricians and Gynecologists (ACOG) for adults of reproductive age, as an aid in newborn screening for cystic fibrosis, and in confirmatory diagnostic testing for cystic fibrosis in newborns and children. The test is not indicated for use in fetal diagnostic or pre-implantation testing. This test is also not indicated for stand-alone diagnostic purposes and results should be used in conjunction with other available laboratory and clinical information.
    Device Description
    InPlex™ CF Molecular Test amplifies specific regions of the CF7R gene in genomic DNA extracted from human whole peripheral blood. Each amplified DNA sample is subsequently mixed with Cleavase® enzyme and buffer then added to a loading port on an InPiex™ microfluidic card. An InPlex™ card contains eight sample-loading ports, each connected to 48 independent reaction chambers. Twenty-eight of these reaction chambers contain dried assay mixes specific for reporting the 23 ACMG/ACOG recommended CF7R mutations and variants. The remaining chambers consist of a "No Invader" Control", an Independent Quality Control. and several unused chambers. After an InPlex™ card is loaded; the channels are mechanically sealed using a micro-fluidic card sealer, isolating each individual reaction chamber from all other chambers. The card is then incubated to allow individual Invader® reactions to occur. Following incubation, the card is read in a multi-well fluorometer and the raw signal data are imported into the InPlex™ CF Molecular Test Call Reporting Software for final result analysis.

    Intended Use
    The Invader® UGTIA1 Molecular Assay is an in vitro diagnostic test for the detection and genotyping of the *1 (TA6) and *28 (TA7) alleles of the UDP glucuronosyltransferase 1A1 (UGTIA1) gene in genomic DNA from whole peripheral blood as an aid in the identification of patients with greater risk for decreased UDP-glucunorosyltransferase activity.
    Device Description
    The Invader® UGTIA1 Molecular Assay is an in vitro diagnostic test which utilizes sequence specific Invader DNA probes, a structure-specific cleavage enzyme and a fluorescent resonance energy transfer (FRET) system combined with universal interpretative software and third party microtiter plate reader instrumentation. Invader® is the term used to generically refer to the patented chemistry on which the Invader® UGT A 1 Molecular Assay is based. The assay is designed to identify specific nucleic acid sequences and query for the presence of known sequence polymorphisms through the structurespecific cleavage of a series of probes that are specifically complementary to TA repeat sequences in in the "TATA Box" of of the UGT1A1 promoter region. In the Invader® UGT1A1 Molecular Assay, two oligonucleotides (a discriminatory Primary Probe and an Invader® Oligo) hybridize in tandem to the target DNA to form an overlapping structure. The 5'-end of the Primary Probe includes a 5'-flap that does not hybridize to the target DNA. The 3'-nucleotide of the bound Invader® Oligo overlaps the Primary Probe, but need not hybridize to the target DNA. The Cleavase® enzyme recognizes this overlapping structure and cleaves off the unpaired 5'-flap of the Primary Probe, releasing it as a target-specific product. The Primary Probe is designed to have a melting temperature close to the reaction temperature. Therefore, under the isothermal assay conditions, Primary Probes, which are provided in excess, cycle on the target DNA. This allows for multiple rounds of Primary Probe cleavage for each target DNA, and amplification of the number of released 5'-flaps. In the secondary reaction, each released 5'-flap can serve as an Invader® Oligo on a fluorescence resonance energy transfer (FRET) Cassette to create another overlapping structure that is recognized and cleaved by the Cleavase® enzyme. When the FRET Cassette is cleaved, the fluorophore and quencher are separated, generating detectable fluorescence signal. Similar to the initial reaction, the released 5'-flap and the FRET Cassette cycle, resulting in amplified fluorescence signal. The initial and secondary reactions run concurrently in the same well. The biplex format of the Invader® UGT1A1 Molecular Assay enables simultaneous detection of two DNA sequences, a non-varying segment of the human alpha actin (ACTAI) gene and the TA repeat in the TATA box of the human UGTIA1 gene, in a single well. The biplex format uses two different discriminatory Primary Probes, each with a unique 5'-flap, and two different FRET Cassettes, each with a spectrally distinct fluorophore. By design, the released 5'-flaps will bind only to their respective FRET Cassettes to generate a target-specific signal. The Invader® UGT1A1 Molecular Assay utilizes four independent wells per sample (one well for each of the TA Oligo mix reactions), to make a single genotype call. Each well contains a TATA box specific probe and an alpha actin probe. The alpha actin probe serves as an internal control to confirm the validity of a given result when a particular TATA box polymorphism is absent.
