Tiling arrays


Tiling arrays
ArrayExpress definition: Tiling arrays are a subtype of microarray chips. They differ in the nature of the probes. Short fragments are designed to cover the entire genome or contiguous regions of the genome. Depending on the probe lengths and spacing, different degrees of resolution can be achieved. Traditional DNA microarrays designed to look at gene expression use a few probes for each known or predicted gene. On top of individual gene expression analysis, other uses of tiling arrays are in transcriptome mapping, ChiP-chip, MeDIP-chip and DNase chip studies and array CGH, among others.
