Overview
The Illumina iSeq 100 Benchtop Sequencing System is a compact, integrated next-generation sequencing (NGS) platform engineered for accessibility and operational simplicity without compromising core NGS performance. Leveraging Illumina’s proven sequencing-by-synthesis (SBS) chemistry with reversible terminators and fluorescent nucleotide detection, the iSeq 100 delivers high-fidelity, clonal cluster-based sequencing on patterned flow cells. Its benchtop footprint and single-use cartridge design eliminate the need for complex fluidics setup or external cluster generation instruments—enabling full workflow automation from library loading to base calling in one instrument. Designed for laboratories with limited space, budget, or dedicated NGS infrastructure, the iSeq 100 supports rapid deployment and routine use in academic research, core facilities, teaching labs, and applied genomics settings where targeted resequencing, small genome sequencing, amplicon analysis, and RNA-Seq validation are routine requirements.
Key Features
- Integrated workflow: All-in-one system combining cluster generation, sequencing, and real-time base calling—no separate cBot or HiScan required.
- Benchtop form factor: Compact dimensions (48 × 56 × 43 cm) and low power consumption enable deployment in standard lab environments without dedicated clean rooms or HVAC upgrades.
- Cartridge-based operation: Pre-packaged, factory-validated sequencing cartridges include flow cell, reagents, and consumables—minimizing hands-on time and reducing risk of contamination or pipetting error.
- Rapid turnaround: Typical run time of ~17 hours for 2 × 150 bp paired-end sequencing, delivering up to 4 million reads per run with ≥99.5% of bases achieving Q30 quality score.
- Low entry barrier: Minimal training requirements; intuitive touchscreen interface and guided software workflows support first-time users and non-specialist personnel.
- Robust architecture: Solid-state optical detection, thermally stabilized fluidics, and automated calibration routines ensure consistent data reproducibility across runs and operators.
Sample Compatibility & Compliance
The iSeq 100 accepts standard Illumina-compatible libraries prepared using TruSeq, Nextera, or other adapter-ligated NGS library prep kits. It supports dual-indexed libraries and is validated for DNA and RNA-derived libraries—including amplicons, plasmids, microbial genomes (<5 Mb), viral panels, and transcriptome profiling (e.g., targeted RNA-Seq). While not certified as a medical device under FDA 510(k) or CE-IVD directives, the system complies with ISO 13485–aligned manufacturing standards at the Shanghai facility and meets IEC 61010-1 safety requirements for laboratory equipment. Data integrity is supported through audit-trail-enabled software (BaseSpace Sequence Hub), aligning with GLP/GMP-aligned documentation practices for non-clinical research use. The platform does not require CLIA certification for research-only applications.
Software & Data Management
Controlled via Illumina’s locally installed iSeq Control Software, the system provides real-time monitoring of run status, cluster density, phasing/pre-phasing metrics, and Q-score distribution. Raw BCL files are automatically converted to FASTQ format and optionally uploaded to BaseSpace Sequence Hub—a cloud-based analysis environment supporting alignment (BWA, Bowtie2), variant calling (GATK, FreeBayes), and visualization (IGV integration). Local analysis options include command-line tools compatible with standard bioinformatics pipelines (e.g., Snakemake, Nextflow). All software modules support role-based access control, electronic signatures, and 21 CFR Part 11–compliant audit trails when deployed in regulated environments with appropriate IT validation.
Applications
- Targeted resequencing of disease-associated gene panels (e.g., BRCA1/2, CFTR, oncology hotspots)
- Small genome sequencing (bacteria, fungi, viruses, organelles)
- Amplicon-based microbiome profiling and pathogen detection
- RNA-Seq for gene expression validation and splice variant screening
- CRISPR editing verification and off-target assessment
- Teaching and demonstration of NGS principles in undergraduate and graduate molecular biology curricula
FAQ
Is the iSeq 100 suitable for clinical diagnostics?
No—the iSeq 100 is intended for research use only and is not cleared or approved by regulatory agencies for diagnostic or clinical testing.
What library preparation kits are compatible?
All Illumina-validated library prep kits—including TruSeq DNA/RNA, Nextera XT/DNA Flex, and Illumina DNA Prep—are fully supported.
Can I perform de novo assembly on this platform?
While feasible for small genomes (<2 Mb), the iSeq 100’s read length and throughput are optimized for reference-guided alignment rather than comprehensive de novo assembly.
Does the system require external compute resources?
BaseSpace Sequence Hub provides cloud-based analysis; however, local analysis can be performed on Windows or Linux workstations meeting Illumina’s minimum hardware specifications (16 GB RAM, 200 GB SSD, Intel i5 or equivalent).
What support options are available post-installation?
Illumina-certified field application specialists provide remote troubleshooting, on-site installation verification, and operator training—both in-lab and virtual—under standard service agreements.
