To quantify the expression of specific genes, researchers can use a variety of techniques, including arrays, PCR, and high throughput sequencing. However, getting accurate results still depends on precisely carrying out these methods, even with increasingly user-friendly technologies. In fact, as more scientists study gene expression, the standards for analysis are growing more rigorous to ensure that only accurate data are published. Likewise, software has been keeping pace, helping researchers follow protocols and analyze their results.
