Overview
The Tecan Spark High-Throughput SNP/INDEL Genotyping System is a fully automated nucleic acid analysis platform engineered for precision, reproducibility, and scalability in molecular breeding and population genomics laboratories. Built upon Tecan’s validated liquid handling architecture and integrated process orchestration, the system implements end-to-end automation of genotype-calling workflows—including sample normalization, DNA extraction (CTAB, column-based, and magnetic bead methods), PCR setup, primer pooling, amplicon-based SNP and INDEL detection, library quantification, pooling, and pre-sequencing quality control. Its core measurement principle relies on fluorescence-based endpoint or real-time detection of allele-specific amplification products—compatible with TaqMan, KASP, and other competitive hybridization or extension chemistries—enabling robust discrimination of biallelic and multiallelic variants across diverse plant and animal genomes.
Key Features
- 384-sample parallel processing: Full walk-away automation from raw tissue or cell lysates to genotyped plates in a single run.
- Reusable stainless-steel 96-channel pipetting probes: Eliminates disposable tips, reducing consumables cost by >60% annually and minimizing plastic waste; integrated wash station ensures carryover-free operation with configurable detergent protocols and waste recovery.
- Modular centrifugation module: Under-bench high-speed centrifuge (up to 4,000 × g) with temperature control (4–25 °C), accommodating up to four 96-well plates simultaneously; extended robotic arm enables seamless plate transfer between deck positions and rotor.
- Barcode-driven sample traceability: Integrated linear barcode scanner reads side-label barcodes on DNA plates and reagent reservoirs, auto-populating LIMS-compatible metadata into instrument logs and audit trails.
- Vertical deck isolation architecture: Optimized spatial layout allows simultaneous access to deck-mounted plates, off-deck centrifuge, and under-deck thermal modules without collision—maximizing deck utilization and enabling multi-step incubation-integrated workflows.
- Flexible nucleic acid purification support: Pre-configured methods for CTAB (optimized for polysaccharide-rich plant tissues), silica-membrane column, and paramagnetic bead chemistries—all validated for yield, purity (A260/A280 ≥1.8), and downstream compatibility with qPCR and NGS library prep.
Sample Compatibility & Compliance
The system accommodates diverse biological inputs—including leaf tissue homogenates, blood lysates, buccal swabs, and cultured cells—with minimal manual intervention. All liquid handling protocols adhere to ISO/IEC 17025–aligned validation frameworks, and the instrument’s electronic logbook supports 21 CFR Part 11–compliant user authentication, audit trail generation, and electronic signature capture. Method files are version-controlled and exportable for GLP/GMP documentation packages. The platform meets ASTM E2524–22 requirements for automated nucleic acid extraction performance verification and is routinely deployed in ISO 13485–certified diagnostic development environments.
Software & Data Management
Controlled via Tecan’s FluentControl™ software suite, the system provides intuitive workflow builder functionality with drag-and-drop step sequencing, real-time run monitoring, and dynamic error recovery. Raw fluorescence data (FAM/HEX/VIC/ROX channels) are exported in standardized .sdmx or .csv formats compatible with Illumina’s GenTrain, LGC’s KlusterCaller, and custom R/Bioconductor pipelines. Instrument logs include timestamped event records for every aspiration, dispense, centrifugation cycle, and wash sequence—fully traceable for internal QA audits or regulatory submissions. Data integrity is enforced through automatic checksum validation and encrypted local storage with optional cloud synchronization (AWS S3 or on-premise NAS).
Applications
- High-density genetic mapping in crop improvement programs (e.g., rice, maize, wheat, soybean).
- Marker-assisted backcrossing (MABC) and genomic selection (GS) pipeline integration.
- Animal breed identification and parentage verification using codominant INDEL panels.
- Pathogen strain typing and antimicrobial resistance (AMR) marker screening in veterinary diagnostics.
- Validation of CRISPR/Cas9 editing outcomes via targeted indel detection in edited cell lines or model organisms.
- Pre-NGS QC of amplicon libraries prior to multiplexed sequencing runs.
FAQ
Does the Spark system support both SNP and INDEL detection in the same run?
Yes—through flexible assay configuration, users can define distinct probe sets and cycling conditions per plate region, enabling concurrent SNP allelic discrimination and INDEL fragment-length analysis within one automated protocol.
Is method transfer from manual KASP assays supported?
Yes—Tecan provides validated protocol templates aligned with LGC Biosearch Technologies’ KASP v4.0 chemistry, including optimized annealing temperatures, probe concentrations, and touchdown cycling parameters.
Can the system integrate with third-party LIMS or ELN platforms?
Yes—via RESTful API and HL7-compliant interface modules, enabling bidirectional data exchange with LabVantage, Thermo Fisher SampleManager, and Benchling.
What maintenance is required for the reusable steel tips?
Daily automated wash cycles using isopropanol/water mixtures are sufficient for routine use; quarterly tip calibration and visual inspection for wear are recommended per Tecan’s PM schedule.
Is the system compliant with EU IVDR or FDA CLIA requirements?
While not an IVD device itself, the Spark platform is widely used in IVDR-aligned R&D labs and CLIA-certified facilities for assay development and verification; full compliance depends on site-specific SOPs and validation documentation.
