Gene Expression Profiling: What It Is and How to Do It

Measuring gene expression is an important part of many life sciences, as the ability to quantify the level at which a particular gene is expressed within a cell, tissue or organism can provide a lot of valuable information. For example, measuring gene expression can: • Identify viral infection of a cell (viral protein expression).
