Protein Arrays

Definition

Protein arrays are experimental platforms used to analyze and detect proteins through a high-throughput format, allowing for the simultaneous examination of multiple protein interactions or functions. These arrays consist of immobilized proteins on a solid surface, which can then interact with various biological samples, making them essential for integrating omics data into metabolic models by providing insights into protein expression, interaction networks, and functional assays.
