LXY3
Based on 1 Customer Validation
LXY3 (LXY2) is a VLA-3-blocking peptide that inhibits the interaction between integrin α3β1 (VLA-3) on neutrophil surfaces and laminin in the basement membrane, thereby preventing neutrophil migration across the tumor vascular basement membrane barrier. LXY3 is used to block neutrophil-mediated nanoparticle release from perivascular pools into the tumor interstitium. LXY3 is commonly employed for targeted imaging of breast cancer.
