The GeneDisc Rapid Microbiology System: System Components The GeneDisc DNA Extractor Used for sample preparation The GeneDisc plate Consumable item in which assays are run. Two of key reagents necessary for assay ( primers and probe) are contained in wells of GeneDisc plate, ready for use. The GeneDisc Cycler Performs assay and records results How System Works The GeneDisc DNA Extractor is used to prepare samples for analysis, based on four simple steps (filtration, sonication, heating and DNA purification). The GeneDisc plate is a two-part molded device approximately same diameter as a DVD. The upper part of disc incorporates a hollow central hub divided into eir 6, 9 or 12 separate sectors, depending on specific plate/application. The lower part of plate contains 36 molded sample wells and micro-channels. Each hub sector is connected by micro-channels to 6, 4 or 3 wells respectively, depending on number of sectors incorporated into plate. Liquid added to a hub sector flows through se microchannels into wells. Eir 6, 9 or 12 samples samples per plate can be tested, corresponding to number of plate sectors. Incorporation of key reagents into GeneDisc plate during manufacturing allows shipment at ambient temperature and storage at 4 C, instead of freezing at -20 C or below (as is typical). This adds user convenience, by minimizing risk of reduced reagent activity due to temperature cycling during freezing and thawing of liquid reagents. Master Mix reagent (supplied for use as an individual tube per plate) is used to run qpcr assays and prevents contamination risks which are inherent in or multi-use formats. Each GeneDisc plate sector contains a positive control well. During a test, GeneDisc Cycler compares positive control data with a stored reference value. If measurements are not within defined limits, that test is automatically invalidated. There is also a negative control well in each sector. Individual batches of reagent and GeneDisc plate are co-qualified during production and ir performance forms part of traceable batch records. For traceability, assembled GeneDisc plates carry printed labels with product description, well identifier numbers and a unique barcode. When a test is run, barcode from each GeneDisc plate is scanned by a reader built into front of GeneDisc Cycler. For quantitative assays, liquid reagent also carries a unique barcode part of both plate and reagent barcodes must match, or instrument will not run. These controls ensure accurate, precise and highly reproducible data, using a very simple format that requires no significant user skills or training. www.pall.com 3
Testing Overview The current test method for quantitative assays is based on filterable samples. Pall also offers assays for certain non-filterable samples, and is developing additional tests. Samples are first filtered, and filter is n placed into buffer. The GeneDisc DNA Extractor may n be used to release DNA from any bacteria present by lysing cells, n to purify any DNA released. Samples and additional reagent (a Master Mix, containing polymerase and deoxynucleotides) are added to upper hub of GeneDisc plate. A cap and interconnected hose (part of GeneDisc Cycler instrument) are fitted to hub and a vacuum is applied by instrument. This vacuum causes liquid loaded into hub to flow uniformly into wells. Mineral oil is added and vacuum step repeated. This seals plate and prevents sample evaporation during testing. The plate is n placed into GeneDisc Cycler. The GeneDisc Cycler is a small footprint (roughly 510 mm x 300 mm x 260 mm) device, with a sliding door at front through which samples are loaded. Inside, re are heating devices required for qpcr reaction, an optical system for measuring fluorescence and control systems. 4
1. Scan barcode to validate GeneDisc plate and test 2. Add test sample to GeneDisc plate The qpcr reaction (along with specific aspects of GeneDisc Cycler) is described in Pall publication USTR 2728, and is summarized in Figure 1 of that document. Briefly, at elevated temperature, double-stranded DNA separates into two strands. A fluorescently-labeled probe binds to one strand and small DNA sequences called primers (specific to a small region of DNA) bind to both strands. This bound probe incorporates a quencher that blocks label from fluorescing. A polymerase enzyme copies two DNA strands. The bound probe is consumed during this process and fluorescent group is released. Therefore, if a specific DNA sequence is present and amplified, fluorescent signal from probe will increase during reaction. This increasing fluorescent signal is used to quantify presence of specific DNA sequence. To run a test, GeneDisc plate is fitted to a drive within GeneDisc Cycler, where it rotates during test. The optical system within instrument is used to measure any fluorescent signal generated during testing. Data is recorded and analyzed using software stored within instrument. Cycle parameters are stored in firmware within instrument. These parameters are not user-accessible but can be user-reprogrammed using security locked files, sent to user by Pall. This allows user flexibility and security of key operational parameters and thus reliability of data generated. 3. Transfer sample to well 4. Load plate into GeneDisc Cycler www.pall.com 5
