hid-nimbus-presto-system

Depend on the automated Applied Biosystems HID NIMBUS Presto System to precisely purify nucleic acids from lysed samples in a 96-well deep-well plate for use in sensitive downstream analyses such as DNA quantification and STR amplification. With rapid, hands-free processing and high-quality yields of even the most challenging samples, forensic labs can enjoy faster turnaround times with lasting confidence in results. The compact HID NIMBUS Presto System combines the Thermo Scientific KingFisher Presto Purification System on an industry leading automated liquid handling workstation. The system is specifically scripted for use with the Applied Biosystems PrepFiler and PrepFiler BTA Automated Forensic DNA Extraction Kits.

HID NIMBUS Presto System offerings

The deck-mounted KingFisher Presto gently and efficiently isolates and purifies nucleic acids from a range of sample types for use in sensitive downstream analyses such as DNA quantification and STR amplification. The process utilizes magnetic particle-based technology to facilitate high-quality nucleic acid purification. When coupled with PrepFiler or PrepFiler BTA Automated extraction chemistries, DNA binds to the magnetic particles, cellular debris/inhibitors are removed, and the bound DNA is eluted through the movement of the magnetic particles across reagent plates (Figure 1).

A dual-position turntable allows processing of one plate while the integrated automated liquid handler simultaneously prepares and transports a second plate, without the need for manual intervention. The automated liquid handler's patented pipette tip technology creates a tight seal for superior liquid measurement accuracy and precision without tip distortion or aerosol generation during tip pick-up and ejection, so plates are prepared accurately and efficiently. The flexible format includes integrated tools like labware grippers to automatically transport plates and around the deck and a barcode scanner to track samples.

The HID NIMBUS Presto System combined with the PrepFiler Automated chemistries is able to repeatedly and consistently isolate or extract actionable amounts of DNA from limited and challenging forensic sample types. Dilution series of blood and saliva spotted on swabs were processed with the PrepFiler 300 μL and 500 μL lysis protocols on the HID NIMBUS Presto, and on the AutoMate Express with the standard PrepFiler protocol to assess comparability. (Figure 2). Similar results were seen with the PrepFiler BTA chemistry (data not shown). Internal Positive Control (IPC) CTs from the quantification assay indicated that all samples were free of inhibitory factors (data not shown).

The HID NIMBUS Presto System delivers DNA from challenging samples and is capable of generating full genetic profiles for use in forensic casework analysis. A variety of known and non-probative casework-type samples were used to evaluate the ability of the HID NIMBUS Presto System to extract inhibitor-free DNA of the highest quantity and quality possible from common human identification sample types; when noted, results from same samples extracted with AutoMate Express for comparative purposes are shown (Figure 3).

The Y-axis is adjusted individually per sample as indicated. From upper panel to lower: Swab of drink can rim extracted with PrepFiler 300 μL lysis protocol; swab of dried blood (2.5 μL) on surface extracted with PrepFiler 500 μL lysis protocol; 1 μL of dried saliva on tape extracted with PrepFiler BTA; 50 mg of slightly degraded bone sample extracted with PrepFiler BTA; 50 mg of slightly degraded bone sample extracted with PrepFiler BTA processed on AutoMate Express.

Designed for use with a streamlined, easy-to-automate workflow, the Applied Biosystems PrepFiler and PrepFiler BTA Automated Forensic DNA Extraction Kits use uniquely structured magnetic particles with novel surface chemistry to help enable inhibitor removal, improving the overall yield, concentration and purity of DNA isolated from both routine and challenging forensic samples. The PrepFiler kits’ components and protocols have been optimized to help maximize performance at each step in the extraction workflow. This means greater quantities of highly purified DNA for improved downstream success. The kit is available in different kit configurations to meet all your sample throughput needs.

The automated liquid handling robot includes a patented pipette tip technology that creates a tight seal for superior liquid measurement accuracy and precision without tip distortion and aerosol generation during tip pick-up and ejection, thus limiting cross contamination.

The checkerboard pattern in Figure 4, alternating high-level control single-donor DNA input samples with extraction reagent blanks, confirms that the HID NIMBUS Presto System does not introduce cross-contamination during automated extraction (PrepFiler BTA and PrepFiler 500 μL lysis protocols were tested).

Reagent blanks are indicated with pink shading and were placed in a checkerboard pattern around high-level control DNA (500 ng in PrepFiler 500 μL lysis protocol study 300 ng in PrepFiler BTA study,) input samples. (Middle panel) Electropherogram overlay of all 36 reagent blanks, displaying all dye channels, purified on the HID NIMBUS Presto System with PrepFiler 500 μL lysis protocol, then amplified with the GlobalFiler IQC PCR Amplification Kit (15 μL of eluate, 29 cycles). The Y-axis is scaled to 200 RFU, One Out-of-Marker-Range (OMR) doublet, one CE artifact spike and one in-bin peak (51 RFU) at an allele not shared with Donor DNA genotype is present above 50 RFU. Blue-channel peaks at far ends of either side of the EPG are the Internal Quality Control (IQC) peaks which are intrinsic to the kit. (Lower panel) Electropherogram overlay of all 36 reagent blanks, displaying all dye channels, purified on the HID NIMBUS® Presto System with PrepFiler BTA protocol, then amplified with the GlobalFiler IQC PCR Amplification Kit (15 μL of eluate, 29 cycles). The Y-axis is scaled to 200 RFU, One CE artifact spike and one in-bin peak (64 RFU) at an allele not shared with Donor DNA genotype is present above 50 RFU. Blue-channel peaks at far ends of either side of the EPG are the Internal Quality Control (IQC) peaks which are intrinsic to the kit. Absence of cross-contamination during extraction process is evidenced by lack of peaks matching donor DNA genotype in any of the reagent blanks.
