  • C12Q 2565/501 being an array of oligonucleotides
  • C12Q 2565/507 characterised by the density of the capture oligonucleotide
  • C12Q 2565/513 characterised by the pattern of the arrayed oligonucleotides
  • C12Q 2565/514 characterised by the use of the arrayed oligonucleotides as identifier tags, e.g. universal addressable array, anti-tag or tag complement array
