Phospho-Protein Arrays

Phospho-protein arrays are laboratory tools used to study proteins in cells, specifically how they are modified by the addition of phosphate groups, a process called phosphorylation. This modification is crucial for many cellular functions, such as signaling and regulation. In an array, thousands of different proteins are fixed on a surface, allowing researchers to test how they respond to various conditions. By applying samples containing proteins and detecting changes in phosphorylation, scientists can gain insights into disease mechanisms and identify potential targets for new therapies. Essentially, these arrays help unravel complex cellular communication.
