Protein Chips: How Tiny Arrays Are Transforming Disease Detection and Drug Research
Protein chips, also known as protein microarrays, are powerful laboratory tools designed to analyze proteins on a large scale. While DNA testing tells us what genes are present, proteins reveal what cells are actively doing at any given moment.
Because proteins control most biological functions — from immune responses to cell signaling — studying them provides direct insight into disease activity, treatment effectiveness, and overall cellular health. Protein chips allow researchers to examine hundreds or even thousands of protein interactions simultaneously using only a small biological sample.
