Microarreglos for the laboratory
A massively parallel analysis technology that uses high-resolution imaging scanners to detect fluorescent signals in arrays of DNA, RNA or proteins deposited on a solid support.
microarreglos guide
Simultaneous study of thousands of biomolecules: gene expression, genomics, transcriptomics, proteomics and epigenomics; also genotyping and biomarker profiling in research.
How to choose microarreglos
- It depends on the image resolution required
- The number of laser channels or excitation wavelengths
- The slide or array formats supported
- The scanning speed and load automation. Specific values come from the catalog (Sanity)
Frequently asked questions about microarreglos
What exactly does a microarray scanner measure?
The fluorescence intensity of each spot on the array, where each spot represents a DNA, RNA or protein probe. The result is a massively parallel measurement of thousands of interactions on a single support.
What scanning resolution do I need?
It depends on the density of the array: current commercial formats require resolutions of a few microns per pixel. A scanner with insufficient resolution mixes signals from neighboring spots and invalidates the analysis.
Are microarrays still relevant compared with sequencing?
Yes, in targeted applications: genotyping, expression of defined panels, cytogenetics and protein arrays, where they offer a lower cost per sample, a simple workflow and mature analysis. Sequencing dominates discovery; the array, targeted routine work.
What determines data quality: the scanner or the array?
Both: the array defines the content, but the scanner provides the dynamic range, sensitivity and excitation uniformity that make experiments comparable to each other and over time.
