What is an array Illumina?
Illumina microarray technology (also known as BeadArray technology) uses silica microbeads. On the surface of each array, or BeadChip, hundreds of thousands to millions of genotypes for a single individual can be assayed at once.
How do the Illumina methylation arrays work?
The Illumina Methylation Assay using the Infinium I platform uses ‘BeadChip’ technology to generate a comprehensive genome-wide profiling of human DNA methylation. Similar to bisulfite sequencing and pyrosequencing, this method quantifies methylation levels at various loci within the genome.
What is Illumina global screening array?
The Infinium Global Screening Array-24 v3. 0 BeadChip is an advanced genotyping array that provides a high-value, scalable, and cost-effective solution for population-scale genetic studies, variant screening, and precision medicine research (Table 1).
How do methylation arrays work?
Methylation arrays enable quantitative interrogation of selected methylation sites across the genome, offering high-throughput capabilities that minimize the cost per sample. Array-based methylation studies can provide valuable insights into the regulation of gene expression.
How do gene arrays work?
Gene arrays are solid supports upon which a collection of gene-specific nucleic acids have been placed at defined locations, either by spotting or direct synthesis. In array analysis, a nucleic acid-containing sample is labeled and then allowed to hybridize with the gene-specific targets on the array.
What is array based sequencing?
Array-based sequence capture expands our capacities to sequence large targeted DNA regions in a less laborious and time-consuming approach. Our array was capable to find the underlying genetic defect in two patients with suspected primary immunodeficiency.
How does methylation microarray work?
The Human DNA Methylation microarrays enable analysis of DNA methylation and a greater understanding of the epigenetic events that regulate gene expression and key biological processes. In addition, we provide a suite of microarray designed to analyze protein, with ChIP on Chip technologies.
How does a SNP array work?
SNP microarray uses known nucleotide sequences as probes to hybridize with the tested DNA sequences, allowing qualitative and quantitative SNP analysis through signal detection.
What is a gene array?
How is microarray different from NGS?
Microarray analysis is limited only by the preparation of sufficient target DNA samples and probe-spotted microarray slides; in contrast, NGS analysis is limited by the number of samples processed in a single run by the physical partitioning or sample-specific barcoding approach utilized.
