Gene expression microarrays
WebOn the older gene expression microarrays, the PM probes are biased to the 3' end of the gene. This was to enhance uniqueness, as well as reduce bias due to mRNA degradation. There are a number of known problems - wrong annotations, probes which do not hybridize well, and missing expression when splice variants do not cover the probes. A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome. Each DNA spot contains picomoles (10 moles) of a specific DNA sequence, known as probes (or reporters or oligos). These can be a short section of a gene or other DNA element that are used to
