DNA Microarray Spotter – High-Precision Automated Printing
The VERSA™ 1100 35-channel automated microarrayer uses a robotic spot printing technique for cDNA microarray assays, enabling both contact and non-contact dispensing of volumes as low as 30 nL. Designed for DNA and RNA applications, it features a fixed pipetting pin system and is optimized for nylon membrane formats.
Microarray Spotting Highlights:
- Volume: ~300 nL per spot (∅ ~2 mm)
- Sample: nucleic acids
- Surface: nylon membrane, 3 mm spacing
In applications such as DiagCor’s disease differentiation assays, fluorescently labeled cDNA strands hybridize on the array. Non-specific bindings are washed away using ReagentDrop™, leaving behind high-affinity matches. The resulting fluorescence signal is quantified via downstream analyzers for data normalization and interpretation.
Application Areas:
- Gene expression profiling
- SNP detection and polymorphism analysis
- Genetic disease diagnostics
- Non-invasive prenatal testing
- Forensics, oncology, and drug-target discovery
With its precision and flexibility, the VERSA™ DNA Microarray Spotter enables efficient, high-throughput genomic analysis across clinical and research settings.
The VERSA™ 110 Automated Microarrayer simplifies peptide synthesis using Fmoc-based solid-phase chemistry, combined with low-cost porous membrane substrates and intuitive software for easy setup and control.
Optimized for the SPOT technique, VERSA™ 110 enables high-throughput, high-density peptide microarray printing with volumes as low as 40 nL—ideal for precise pipetting of amino acids and reagents.
“Stable and reliable—we’ve had zero breakdowns in years. VERSA™ offers higher density, faster printing, and greater accuracy at a lower cost.”

Background
Solid-phase peptide synthesis (SPPS) links amino acids via peptide bonds on a solid support. This method enables the production of complex or unnatural peptides, backbone modifications, and sequences not easily expressed in biological systems.
At National Taiwan University, the VERSA™ system is used to print cell microarrays onto microscope slides for studying cell signaling pathways and drug binding interactions.
Printing Specifications:
- Spotting volume: 100–300 nL per spot (∅ ~2 mm)
- Sample type: Uniform or varied cell solutions
- Format: 10×10 array on 15×15 mm microscope cover glass
After spotting cells, drug molecules are applied to the array. Following incubation, cell morphology is analyzed under a microscope to assess drug effects and pathway activity.
