Common Mistakes When Using “microarray”
- Misspelling as 'micro array' or 'micro-array' (though the latter is acceptable).
- Using it as a verb (e.g., 'We will microarray the samples' is non-standard; use 'analyse by microarray' or 'hybridise to a microarray').
- Confusing with 'microtiter plate', a different high-throughput tool.
FAQ
Frequently Asked Questions
Essentially, yes. 'DNA chip' and 'gene chip' are common synonyms, though 'microarray' is the more formal and encompassing technical term.
No, it is not standard. The word is a noun. The correct phrasing is to 'analyse by microarray', 'hybridise to a microarray', or 'perform microarray analysis'.
Its primary purpose is to measure the expression levels of a large number of genes simultaneously or to genotype multiple regions of a genome, enabling high-throughput biological analysis.
Yes. Microarrays detect known sequences using pre-designed probes. Sequencing (like Next-Generation Sequencing) determines the actual nucleotide order of DNA/RNA fragments, discovering known and novel sequences.
