Gene expression assays

Gene expression assays are laboratory tests that measure how actively genes are being used in a cell or tissue. They identify which genes are turned "on" or "off" and to what extent, providing insights into biological processes and disease states. These assays help researchers understand cell function, diagnose certain conditions, and develop targeted treatments by examining the patterns of gene activity. Essentially, they reveal the activity level of specific genes, similar to checking how much a particular light in a room is turned on, providing important information about health and biology.
