PH-Low Insertion Peptide

PH-Low Insertion Peptide (pHLIP) is a short, pH-responsive peptide capable of inserting across a cell membrane to form a transmembrane helix at acidic pH. pH-Low Insertion Peptide targets the acidic tumor microenvironment for tumors at early and metastatic stages with high specificity, used as a specific ligand. pH-Low Insertion Peptide successfully modify polylysine polymers to have the pH-responsive capability. pH-Low Insertion Peptide-based targeting of cancer presents an opportunity to monitor metabolic changes, and to selectively deliver imaging and therapeutic agents to tumors[1][2][3].
