Frequently Asked Questions
What is a peptide array?
A peptide array is a chip containing thousands of different peptides arranged in a grid. When exposed to tumor proteins, it reveals which peptides interact with which cancer-related molecules — like a massive speed-dating for molecules.
How does this help cancer treatment?
By mapping which peptides bind to tumor-specific proteins, researchers can identify new drug targets, discover cancer biomarkers for early detection, and design targeted peptide therapeutics.
