Definition / general
  • Researcher should ask if microarray technology is really necessary for a specific research application because:
    • Microarray is time consuming and slow to setup, difficult to validate, expensive and requires great analytical expertise
    • Microarray can give an enormous amount of irrelevant data
    • Available chip may already have the desired set of gene sequences
    • Multiplex PCR or a custom chip may be a better method of analysis than employing a genome wide array
